This is one of the best explanatory Auto repair videos I've seen from Nigerian TH-cam and I'm proud. I'm a DIY enthusiast and do basic repairs on my machine myself and this definitely explains my inconsistent fuel economy and this is the only code on my Ford. Thanks for making this
@@DIYAutoworksNG the map sensor is together with the EGR valve and I could not find it here in Nigeria so far but already ordered and expecting delivery. The car is kinda scarce though despite being a Ford. Many don't even know the model exists until I send pictures as evidence. I will appreciate if you have a place I can get original parts and sure to have for my car. It's Ford Five Hundred
I feel you. Being Ford 500 would have something to do with the difficulty finding parts. Not common. I've seen it maybe once or twice. If you've gone to the major used parts markets in your state, then it's to import as you've already done. I used a combination of Amazon, Rockauto and authorized distributor sites.
I have some of the symptoms, especially sluggishness, bad fuel efficiency, low idle - to stall, when I reset cel codes (intermittent P0325) I assumed the MAP was having issues that were compensated by the ECU after driving some distance. No MAP codes though.
I drove with the mechanic forgetting to install the intake tube to the airbox for hundreds of miles.. p0171 and left at 50%! I installed it back and the trim is now near zero and runs good again but I'm worried I hurt my car. 2004 highlander v6
I'll say just monitor your oil level for the next couple of weeks.. If you're in a region with sandstorms, then the risk of damage would be certainly higher.
it would be good if you showed the actual values on a diagnostic scanner, showing the engine operation with a damaged map sensor and then with a new or replaced map sensor. Great video bro, best regards.
Great suggestion. I wish TH-cam allows the addition of content to an uploaded video; would have done this. Thanks for the compliment too. All the best.
@@DIYAutoworksNG Thanks for Your answear. I have a one question. Are You from India? In every Yours video I Heard traffic sounds typical of this Country.
Checking the wiring involves confirming the following at the MAP connector: 1. Good ground (power probe will help) 2. 5v at the reference line 3. Checking for voltage on the signal line. Also check for bent/flux/corrosion on the pins. If all these checkout. It maybe a bad PCM especially if the reference voltage is off.
My Ford explorer 2015 keep showing this code p0107 even wen I have replace another new map air sensor but it's still continue showing that same code,.. which I don't even know what to do..pls I need a solution
Check that the electrical connection is tight. Also that the contacts are clean. You may clean the contacts on the connector with electric contact cleaner. Also check that there's no short or open in the wiring.
Could a dirty map sensor cause me to get bad readings for other sensors? My Intake air temp sensor was off, throttle position sensor was giving bad readings, and my absolute manifold pressure was low on the scan tool.
I would say in some instances yes, however, intake air temp and MAP are 2 different things. I don't see a connection. Do you have DTC's on the car? What car is it?
I only get a P00BC code - 2009 X5 - Did find some oil in the MAP sensor??? No vacuum leaks, never a miss fire, ALL has been super checked, all sensors are up to par; so; what could be the matter? Could the MAP sensor be bad? None of the codes you mentioned, EVER. I have no lack of power, hesitation is at idling, and some sort of sleeping (sometimes) as if is transmission related but I don't think so.
Most references I saw online with the P00BC is to do with the MAF sensor not the MAP. Is it different with BMW? Check for dirt, poor connection and lastly if its bad.
@@DIYAutoworksNG thanks but this code is not specific as it should be. All sensors are new, some, checked the others. I wonder is through the engine pulley gasket/seal. I had the serpentine belt snapped but only drove 2 miles home at 40 mph. Did check the valvetronic and the two screws required some tightening but no oil leaks or in spark plugs tube. Is insane! I’ve EVERYTHING imaginable and keep the car top notch; only 108K and immaculate all around. I don’t trust dealers; they will get you for every penny and you come out empty and additional issues you never had. Curious is that I have no oil leaks from pulley engine seal.
Could this cause a P0171 system too lean and a P430 catalyst efficiency below threshold, so far installed brand new exhaust manifolds, put in a brand new mass air flow sensor, brand new bank 2 downstream o2 sensor and codes still come back after being cleared and even checked for vacuum leaks and found none. This is on a 2007 Cadillac Escalade ESV with a 165,xxx miles on her.. been trying everything
Since your car has 2 banks, you have something occurring just on bank 1. I see you changed the bank 2 sensor 2 downstream O2 sensor. Its the bank 1 downstream sensor that could be the culprit. A dirty MAF can cause this, but I would expect to have the same code for bank 2 (P0174) if it were air supply related. Same goes for the MAP. Since this is not the case, think of things local to bank 1. Anything offsetting the air-fuel ratio towards the lean end will cause this. I am not familiar with this brand, but does it have 2 fuel pumps or PCV valves? Low fuel pressure or cracked or stuck open PCV valve, vacuum leaks on bank 1 are other potential culprits. Reviewing short and long term fuel trims will help give a sense of where the problem lies. E.g. If you're having a reduced fuel supply issue, the STFT may be normal at idle but will go lean when you snap the gas pedal and hold at about 3000RPM. Is the car having any other symptoms?
@@DIYAutoworksNG i even sprayed down every where too looking for a leak for change in rpm, around intake, throttle body and all hoses, vacuum lines, brake booster and did see or hear no surge with rpms but another strange thing is ever since the P0171 code i get for a lean running i also get a the message on dash that also says service stabilitrak and service traction control but only at idle but once i step on the gas or on motion it goes away till i stop again
@@DIYAutoworksNG Ahhh okak which my short fuel trim sits around 0 and and 5 while my long trim sits at 24 percent and goes down when i rev it up, but now i did buy a new map sensor and replaced, old one I pulled had a coating of oil but that wasn't it either so today i bought a new purge valve and going to change purge valve of that doesn't do it then I'm going to try to put in a new coolant sensor. But you think i should change my bank 1 o2 sensors then or will i onow they are all original except the one on bank 2 sensor 2 i changed last weekend.
@@DIYAutoworksNG And as for other issues she seems to drive pretty good, doesn't idle or shake or anything, sounds a bit loud and can hear exhaust on driver side right about at catalytic converter when im giving it gas to get up to speed but she seems drive pretty good other then that but the i was contributing the to the stainless steel performance exhaust manifolds i had a shop install to replace old rusted cracked one that had broken studs and wanted stainless steel so i wouldn't have to worry about it rusting away again like the oem one
@@DIYAutoworksNG Too bad i couldn't send you a screenshot shot pf the data scan tool, i use the bluedriver and the MX+ scan tools even monotoring the o2s one side looks good but other side it shows the same data from sensor 1 to sensor 2 up and down on the graph equally
Hi, can you tell me if the pressure reading from a MAP should be dead steady or can there be some variation? I have three pressure sensor in a bmw m235i ( ambient pressure, intake charge pressure and manifold pressure). Two ( ambient pressure and manifold pressure sensors) are dead steady at 1030 hpa whereas the intake charge pressure sensor varies between 1027-1033 hpa when using a ODB scanner . All readings are before starting the engine. I'm experiencing a fault code (Throttle valve opening angle absolute pressure intake pipe comparison pressure too high) on startup and was wondering is the MAP sensor which is showing a variating value could be the issue.
Hello, MAP readings are meant to vary with the degree of opening of the throttle. It should be equivalent to ambient barometer readings in the 'engine off key on position' before starting the car. After starting it should vary based on the first reason given above. I am not too familiar with this BMW setup, but think that that 3rd pressure sensor should read ambient too before start. Could be wrong though. Have you checked vacuum lines?
@@DIYAutoworksNG Actually what I meant by variation was that the reading from the charge inlet MAP was moving between 1029-1033 hpa (very quickly) before the car was started whereas the other two MAP were not changing at 1030 hpa. Basically wanted to know if a MAP sensor was 'bad' if it was showing changing values with no change in conditions.
Hello. Its usually in very close proximity to the throttle body. I don't know Hyundai very well but this is the standard position on most vehicles if it has a MAP sensor equipped.
This was the mist thorough an easily understood explanation of how a sensor operates and what to look for when not properly working.
Many thanks!
That was VERY helpful and informative! Thank you! I am a woman doing my own mechanical work! I appreciate you!
You are so welcome! Hats off to you!

The P0325 points to a knock sensor issue which can cause all the problems you stated.
Well that was a simple repair.
Yep

Good you caught it. Guess you'd know if the engine was hurt if it starts burning oil. Finger crossed nothing happened.
@@DIYAutoworksNG you think I'm ok? :(
I'll say just monitor your oil level for the next couple of weeks.. If you're in a region with sandstorms, then the risk of damage would be certainly higher.

No.
The cars I work on are parked quite close to a busy road. Lol. Similar sights and sounds 😁. I film mostly from Nigeria.
@@DIYAutoworksNG what time is it now in Nigeria?
9:39am on the dot!
I got the same code for P0107 run every diag change the sensor still no solution check wiring and everything is good

1. Good ground (power probe will help)
2. 5v at the reference line
3. Checking for voltage on the signal line.

Where can I get that 10mm bolt from?
I usually get from Amazon or hondapartsnow.com

@@DIYAutoworksNGcould it trigger a crankshaft position sensor code ? Or could the crank shaft position sensor code trigger the map sensor codes ?
Why can My 2002 Honda Odyssey not rev past 3000 rpm?
It's in limp mode. You need to have the car scanned to identify the diagnostic trouble codes.

It should be steady with the engine off.
