Good news. I think I got the problem that cause the high fuel consumption yesterday. I just want to verify that it was that before I post the video. It is a factory fault. Luckily free to fix it. Our car idles much less noisy now.
The TPS can be set if you look at it, there is a one normal hole and the other is longer as it can be adjusted. Get a multimeter and back prob the center wire for voltage. The tps should be around 0.5v. Open the throttle slowly and if you see and rash jumps in voltage or if it drops down while increasing it its faulty. Fully open it must not be more than 5v. Knock on the sensor as well and if the voltage spikes up and down then its faulty. What is actually happening is once u let go of the accelerator the ECU thinks the throttle body is open hense why it idles high or jerks when changing gears or braking.
To remove the small one you need to use small rashes on small extension and I have been advised not to use a cap cleaner except throttle body cleaner and it it works on me
had a similar issue but on a Nissan, what had happened was oil got in the intake, created sludge and resulted in running rich. solution, clean the intake manifold.
You can set your tps with a t10 torx. Get a multi meter as well. Not all brands have the same spec. eg: euromoto and Sebring, doesn't run on the same spec. The car should idle at 850 rpm not 1000 rpm. The part should put 0.5 volts with the ignition on. Try it! Trust me, that's a battle I can say I triumph!
When changing idling valve take out battery terminals off then instal the sensor the put the battery on again then start the car, it will rev higher then tap the accelerator and then switc it off then back on again then it should be fine. Opel idling valve is not a plug and play guys .
Hi thanks for the video my with my corsa it's computer box was water damage so I bought a 2chand loom with it ignition and computer box so the car starts but doesn't ref up and the manifold gets very hot any suggestions please
The throttle position sensor is just a variable resistor or potentiometer that can be easily checked with a multimeter. Mine changes from about 6.5k to 900 ohm max to min. The idle control sensor is actually a actuator. If it gives problems,take it out, connect plug. Hold the tip so it does not go in, and switch on car. Switch off and let it go out. Continue untill it is all the way out. Then clean with break cleaner/ thinners. Push some grease in to hole. Put back pin. Now switch on ignition and keep pushing the pin in. It should stick out enough when you put it back in throttle body, otherwise you get high idle. To summarize, every time you switch on ignition the idle control valve pulls in a little to increase idle speed. Then it goes back out to lower idle. If it is sticky it mostly pulls in but doesn't go out an cause high idle. A Little cleaner an grease causes many more available parts at the dealers for everyone. Moral of the story, throwing money at problems doesn't solve them.
GM still has original spares. You just won't like the price. All aftermarket parts don't work. That's because they were not specifically made for the Corsa B and the tolerances aren't correct. So if you want the genuine idle valve sensor you will be looking at 5k. And it will work as intended. Sad but true. (Same for tps which genuine part is close to 3k).
@@CedricWyeth I see 3 pipes on the throtle body. I wish I could share the photos. One is going from the back of the trhotle body to the map sensor. The second is going from the top of the trhitle body to the tapet cover. The third is going from the right side of throtle body to the fuel sensor on the injector rail. I think if you watch the Corsa project video where I did the head gasket you might see them in the video as I took alot of video from the top.
I had similar problem and all i did was swap my idling position sensor with a scarp car and my idling was perfect....what you did by unplugging the sensors does not work you have to test with parts of the same car..
7:58 seemed like auto choke on a cold morning but obvs not the issue. Also for excess fuel consumption check two things, clean the airflow sensor and I also found mine was leaking from the fill up rubber tube and breather which I will be replacing shortly as I just did a head and cam job on the fucking bastard lol I'm worn a bit thin 😂
My corsa gives me the same problem.. changing the TPS seems to sort it out for a few months and then i need a new one, maybe because OEM parts are no longer available and the aftermarket parts dont last🤷🏽♂️
OEM spec parts is available at Goldwagen. IDC valve is R320 and better quality, but I don't believe the IDC valve is always the culprit. You trying to put a bandaid on and underlying issue. I'm still trying to figure it out.
@@hhlhcier good day. I don't know. I took it to someone else to check for me. And he used a couple of android apps to analize the computer. And when I asked him what he used or what app he used he told me he is not going to give out that information. I think it was a dick move on his part but what can we do.
@@CriPtZoNe Thank you for your reply! I have misfire and the engine runs not smooth, also problem with starting. I've changed the spark plugs, connectors idle valve, map sensor, ignition coil pack it's better, but the engine is still not running with full power. I could see that the new spark plugs are all very black, but not full of oil, and just test drive the car around the corner. Now it's difficult for me to find the problem.
Been having the same problem with my corsa for months now. Spent a shitload of money to replace everything from sensors to fuel pump. Nothing works. Time to scrap the shit.
My corsa does the same thing and I have changed all the sensors but the problem does not get fixed. It starts well and idling less 1000rpms but it changes after some time and sometimes it waits for me to put it on gear and it would start idling over 2000rpm. I am not even of buying a new throttle body or doing an engine swap because this corsa engine is giving me headaches with this idling thing.
Before you do anything else look at the timing gear at the bottom. Sometimes the key way gets worn. It moves half or one tooth out of time as you drive. That will also cause loss of power.
@@CriPtZoNe Thank you. Mine has power, it is the idling problem that I am facing and just the otherday it got worse, before I used to switch the car off and start it again and idling would be gone but now nothing works. I got the throttle body cleaned sensors replaced but still does the same thing
hi, i would like to know what diagnostics tool your friend used to run the diagnostics. i have trouble getting someone with the right tool to run diagnostics
@@CriPtZoNe I'm having the exact same issue as shown in this video. Also, battling to find an app to use with the OBD2. It reads the OBD unit but it says it's not connecting to the ECU..
Would really appreciate that. I changed my spark plugs and leads today.. still misfiring and even worse now. Cleaned my Idle control valve and it's also revving even higher now, up to 3k. I am SO confused.. but like you said, the TPS may be causing all the problems. Really appreciate this video, I feel like it's giving me a lot of answers @@CriPtZoNe
Hie , i have a corsalite which after you rev it stalls or switch off even when driving as soon as you want to change gear it switches off the engine, on the corners if you stops it doesnt idle and stops again . I have changed twice the idle and throttle sensors still no changes. I changed the map sensor too but still have the same problem. The mechanic is also confuses pliz help me diagnost this problem ..
Look at the timing gear on the crank. Remove timing belt and see if the key way is worn. Just one tooth out will spoil the entire idelimg, performanse and fuel consumption.
Mine revs fine at 1000rpm problem is sluggish acceleration,i cleaned throttle body, changed tps ,spark plugs and wires but still the same 😢and chows fuel like crazy .
Or map sensor, my Opel Corsa utility does the same and I changed what you changed, but after I cleaned a map sensor was fine for about 10km drive for the first time and then it came back but occasionally this time so I'm changing the map sensor this week then from there I check the key way as my last resort, but let's see who wins first and share the part replaced nhee? On this comment deal!
Hi I'm in need of advice...I have a opel corsa lite 1.4i and been giving me some problems.okay once driving about 3-4 km then the car starts to jerk n losing power,sometimes it comes right after few minutes and most of the time it take about 15-20 mins to come right whilst driving.so now got a mechanic and so we started trying to find the fault we tried new plugs new bougi cords new fuel pump and filter cleaned the injectors cleaned the fuel tank cos it was very dirty checked the timing it was off, new water pump and fan belt put in. But the car still has the same problem that jerking and losing power. I was told by another guy who had the same problem, it's the idle valve sensor or the fuel pump relay ...which I recently bought both the mechanic said no it could be the throttle body sensor or the coil so anyone had this problem with their corsa any suggestions or advice will be greatly appreciated.thanks
Sounds like something is failing. Could be the petrol sencor. The ideling control sensor will make the car idle verry high or verry low. And the engine check light will come on. Tps sensor high ideling but no engine light. Could be an injector messing around.
Check map sensor as well. Otherwise you have to check the timing gear at the bottem pully to see of the key way is worn. That will effect your timing with one tooth causing power loss.
When u install a new idle control valve the rerv will be extremely high, dont panic its normal let it run it will come down to normal in a matter of minutes, i knw its normal to panic wen it happens😂😂😂 buy a carb cleaner for control valves dont buy sensor immediately wen u experience a an idling problem...and with regards to the petrol this car has a problem with the petrol pump sending unit which will give u false petrol reading
if you cant see it, ill tell you what i noticed in this video, the accelerator cable is too tight!! you need some slack at the cable end, otherwise it will interfere(confuse) the idle stepper motor, in this case, higher revs. the cable is adjusted at the pedal end, if need be? The spring you forced NEVER was/is an issue, you just making matters worse
