- The 500 manual transmission uses a clutch switch in the panel box to permit the car to start. This video shows you how to replace the clutch switch. Fits 500 pop, sport, lounge, Cabrio and Abarth with a manual transmission uses the switch above the clutch pedal assembly. Covers models from 2007 thru 2019 includes North American manual transmission models. Please read the notes below, you issue may no be the switch but one of the following things you can do yourself and save money and time:
Special notes for North American Fiat 500's: If you are getting a no start situation when you turn the key, before doing this clutch switch replacement review these things. Disconnect the negative (black) ground terminal:
1. Clean the battery connections, especially the negative ground! Often times a poor or corroded connections will cause all kinds of check engine lights and multiple failures that go away as soon as you clean the cable connections. Also, if your battery is more than 3 years old, consider replacing it. Trust me on this, I have sold 2500 new Fiats and this is what is common in older 500's. Battery related issues are the #1 cause of Fiat 500 starting and running problems! The Mopar battery is only 500 cranking amps. The NAPA #7547 Legend series is 650 CCA and fits perfectly. This stronger and better battery is often cheaper too!
2. Put car up on ramps, disconnect battery and take off lower splash shield (6 bolts, use 10mm socket). Find and loosen the 1/2" wide copper mesh ground strap bolt on the lower driver's side under battery tray area, clean and reattach to make sure you are getting good ground. This costs nothing to do.
3. While the battery is disconnected, get under the car and find the starter motor. Loosen the 2 bolts a little, then retightening the starter bolts. They can get a bit of surface corrosion and do not provide a good ground, making for a no start condition. Usually just loosening a bit and then tighten the bolts back up gives gives them good contact surface again. This costs nothing to do.
4. Change the battery in your key fob, it uses a CR2032 button battery. Remember the Fiat key is a transponder key, the CR2032 battery in the key fob has to communicate with the receiver ring antenna located in the ignition switch. You will see a little silver flat head slot screw inside the key fob, turn it 1/4 turn to open the battery door. Make sure you install the battery the same way the old one came out. You can find these CR2032 batteries anywhere and costs less than $3.
5. If your car has been sitting, it may crank but not start right away. This is because the oil has to get to the top of the engine to open the intake valves. Keep your foot OFF the gas so you don't flood it or foul the plugs! So be patient, crank the car for about 15 seconds and then wait 15 seconds and try again. A couple of tries it should fire, might be a bit rough on start and puff of smoke but that is normal. If you do not change the oil often or oil is old and thin it could be hard to start after a long period of non use.
6. Check your oil level. Pull the dipstick out before starting and it will give you the exact read. Remember to use 5w-30 for non turbo, 5w-40 synthetic for turbo... Use 4 Quarts on these, NOT 5! Change oil and filter every 5000 miles for best results. - ยานยนต์และพาหนะ

Thank you so much for this video. I was about to take my Jeep Renegade to the dealership because I could not figure out what was wrong I just knew it had something to do with the clutch safety switch. I had the switch out because I was testing it and it was good so then I was out of ideas. My husband sent me this video I immediately checked and BAM my Renegade started right up. You my friend just saved me hundreds or thousands of dollars of it being at the dealership to get it serviced. Again thank you so much!!!
Great explanation and how to. Here in the UK we have a slightly different clutch switch but the way it connects is exactly the same so thanks!
Thanks Ray glad it helped. I found on my car that the non-starting condition was also related to a corroded ground connection which is under the engine, its a bolt connected to a wire mesh ground strap.
Many thanks for this tip, so easy to get the thing out when you know how! Thanks again.
Hey John, replaced this sensor today and I found it really easy to get to the back of the sensor if you reach around the pedal box from the right. I am trying to fix a p0805 error. I find the information on these cars a bit confusing as my car will just start even when it’s in gear. (2016 model). I cleared the ecu and hope the error doesn’t come back. We’ll see. I also tried fuses but they all seem good. Thanks for the video!
thank you so much for this video! we just came across this issue and now i know what i'm dealing with! thanks!
Greets, from Germany, have to change that switch now. Perfecto explained ❤️
Love it. Great ideia. Um Portugal there is no vídeo of This. Thanks
Great video - Thank you
I tried and tried to replace this without removing anything. So I needed to remove the dash for something else and it's so nice to get to the switch from the top😂
Thank you so much I guess my switch had enough after 160k miles lol thank you
Thanks Jerry, since I made this video there’s a few other things to check. One of the most important is the positive cable connection to the starter solenoid which can get a little corroded. The other things are the ground strap at the engine to frame itself web strap made out of copper.
Thank you SO much for this video!!! I have a 2012 Fiat 500 Abarth and I love it, I went out to start it the other day and it just wouldn't work, but pop the clutch while rolling to jump start it.
(As an aside, waaaaaayyyyy back in the day when I still lived in the Carolinas, I went in Benson Fiat and test drove a 500C Lounge in the summer of 2012 and fell in love with the car after wanting on I saw on BBC's Top Gear. I was never able to make the purchase I planned on because I ended up getting laid off a few weeks later, but everyone was so nice. Good to see you guys are still around!)
I just disconected the small yellow snap-arm from the clutchpedal and let the spring in the swtch go back to the bottom .No more startproblems. But you have to let the electric 3 pin cable be still in place.
ty, very detailed
Thanks for All information I don’t know I can use it or not my Start stop light turning around after five minutes I drive the car
Nice one
This video was so helpful. Thank you!
Be sure to check and clean the wire mesh ground strap points also and slightly loosen and the two starter bolts and then retighten them to make sure that you’re getting a good ground there. I discovered that it is important for a reliable operation.
Hi
Is it work as a start and stop ?
When you have a start stop light on
That clutch switch is responsible only for a start up the engine or something more? For example for giving an information to the ecu while switching gears about clutch position to reduce shakes etc. ?
Is it possible to simply bypass this switch? I hate having to press the clutch all the way to the floor in order to start the engine.
Hi
Can you help me ?
hi i have p0725-66 in transmission and between 2 and 3 car slipping fiat 500 dialogic gearbox
Thanks for sharing. Any advise you can give me for my fiat abarth 2013 gear. its hard to put in 1st and 2nd and reverse. very notchy. feels like its going to break is I force it in. thank you
The shifter is cable actuated, they make a replacement repair kit sold on E bay. First be sure the cables under the shift boot are not binding and well lubricated. If they are kinked you may need to replace. www.ebay.com/itm/125041147617?fits=Submodel%3AAbarth%7CModel%3A500%7CMake%3AFiat&hash=item1d1d087ee1:g:VqsAAOSwIBRhsMek
@@fiatofgreenville thank you good sir. I’m now a subscriber
Hello. This is the closest I have seen to a solution to my problem. I am trying to get the clutch/brake pedal out on my 2015 Fiat 500. I have all the bolts loose and I think everything else. I don't want to pry to hard and it seems mostly loose but no give. I live pretty far from a Fiat repair shop. Any one that can help me get the thing out would be helpful. After a stroke life is a very interesting place. It looks like everything is disconnected and still the assembly refuses to come out. Anyway, hope the description is enough to give you an idea.
Hi John - greetings from the UK! Many thanks for your video - very helpful. We have a 2014 500 Lounge which is throwing a P080A fault code regarding the clutch position sensor / switch. I cannot find any more detail on this, but it seems to point to the switch. The weird thing is that the car starts whether or not we depress the clutch, and I'm guessing this isn't supposed to happen, which also points to the switch, or...?
I’m not sure about the UK models, if they can be started without the clutch being depressed. In the USA the clutch pedal has to be toward the floor no matter if the transmission is a neutral or in gear. It’s possible that lever switch maybe stuck. One thing to make sure that the pin is making the switch move. There are cases where the pin breaks off. The other thing I learned it’s very important that the mesh ground strap mount points are clean from engine to the chassis and starter motor bolts are free of corrosion too.
@@fiatofgreenville Thanks John - I'll check the earth strap. I had a look at the pedal and it is operating the switch. Chris
To my astonishment when I changed out the clutch switch, just a couple months later it wouldn’t start again till I cleaned the mesh ground strap from engine at both ends as well as the starter bolts. Now it works fine.
@@Showing_the_car_ did u find the issue in the end? Same thing here, everything seems ok just get the error code
@@IsaacPevy Yep, it wasn't the switch - just needed the error reset
My 500 is now a driveway decoration for a week...
i replace the switch.. still no crank.
check the T20 relay nothing (switch to other relay, pull the relay and tested ouside given 12v and see if the relay is activated and i have connection in the other 2 pins)
change the engine ground and clean the contact
could be a problem in the wire of the switch. I know that is posible to scan it and check if the clutch position switch is activated or not.
could be a problem with the ground on the starter? but if is the case the t20 relay should be activated?
Thanks for your time...
Hi Alonso, after I replaced mine everything worked great for quite a while and then it started doing it again. So I cleaned the grounds including the mesh ground strap but one thing that I did not clean was the positive cable that goes to the starter solenoid. It is inside a little black plastic case. I think sometimes water gets in that case and causes a little corrosion. So disconnect the solenoid post, use a 13 mm socket to loosen the positive wire, clean it tighten it back down reconnect the ground and try again.
My clutch pedal shaft bushing came off from the metal ball, lost the clutch in traffic
Great video , does it need some sort of calibration? Or just plug back in?
Does it need some sort of calibration ?
@@omeraltn2819 it did not needed ;)
Merci heureusement que je suis tombé sur cette vidéo j’ai pu changer ce capteur sur un 3008 sans aucun problème et sans outil .Sinon j’aurai cassé un morceau c’est sûr
I got stranded a few days ago in my 2012 Fiat 500c when I engine-braked at a red light and my clutch pedal mysteriously rescinded (seemed to just disappear from under my left foot). I got it towed to a Fiat dealer service dept. But, it'll be a couple of weeks before they can look at it... Any theory about what broke? A little more than a year ago, the shifter cable itself had to be replaced..
I love my Fiat; it's fun to drive. But, the manual shifter/transmission seems to be the weak link in an otherwise great car.
Hi Harry... the clutch is hydraulic and uses brake fluid from the brake reservoir to make the clutch work. Check the fluid level under the hood near the battery, it its very low it could be a leaking hydraulic line or the throwout bearing assy. The fluid could be collecting inside the transmission case, so it may not be dripping out on the driveway.
@@fiatofgreenville Thank you, Mr. Montgomery! Whenever I call the dealership service dept., they jabber about how long it takes to get parts in... Meanwhile, they haven't even looked at my car yet and close to two weeks have gone by.... A fellow at work today heard me describe the phenomenon and he spit out about it being a hydraulic issue. So, it's likely you're exactly right.... Now to get the dealer's people to stop jerkin' me around. I left them a phone message with what you suggested to look at...
Turns out this was the cause for my car reading a message stop start unavailable, also the Anti stall wasn’t working, I thought I need a new battery but turns out my switch has just come loose reconnected it everything was okay
Can you replace this part without having to take the pedal box out?
Hi Tony yes you can certainly replace it with the pedal box in there but I recommend taking out the seat to give you more room. Not sure what’s happening with your car but one thing to check is to make sure that the starter bolts don’t have a little corrosion on them. I slightly loosened them and tightened it back up and it seem to work very reliably. Typically this clutch switches don’t go bad a lot but you can get some corrosion at the ground strap near the starter and the starter bolts and that could be the source of your prissue
@@fiatofgreenville Hey John, thanks for the quick response. I've actually managed to take the clutch safety out and cleaned the contact points on the PCB inside the safety, which were quite dirty. However it still doesn't start, so I'm going to give your advice regarding the ground strap. Any idea if there's a diagram available I can look at to help me locate it?
@@tony_ypnar Just put the car up on ramps if possible, disconnect battery first and pull off the splash shield. Make sure there is no power to the vehicle since you are working with the starter. Find the starter, which is above the drivers side drive shaft on back of the engine. You will see a mesh ground strap in same area, loosen bolt and clean it up. Then you'll see a bolts fastening the starter motor to the block. Loosen those just a bit and retighten, which will clear any corrosion. While you're up there make sure the cables to the starter is tight. This is a good practice as over the years we have seen starters that have high resistance and especially when hot, won't start.
