  • The PCM doesn't even see the O2 sensor until engine temp has reached operating temp,the vehicle goes from open loop when cold,to closed loop when warm,where the PCM uses the O2 sensor to measure the rich/lean of the exhaust content,and from that,adjust fuel richness to achieve 14.7 to 1 air/fuel ratio.So when cold,the O2 sensor is out of the picture anyways.When unplugging sensors,it can be deceitful.The PCM has a program whereas,if a critical sensor (such as the mass air flow) is somehow damaged and out of the picture,the PCM will substitue a generic value that will allow the engine to stay running.So,by unplugging the MAF,it did try to run on it's own better than plugged in,there's the problem area.The vehicle is running better with the MAF unplugged,because the MAF is likely bad,and the PCM is substituting it's generic value when it IS unplugged.Something to recheckThe PROM update is a newer program for the PCM,and likely won't fix it unless the PCM is bad.I would try a good used PCM as a last or later resort,because i have seen my fair share of defective PCM's too.I have taken some PCM's apart,and found capacitors that had gone bad and leaked all over the circuit board,mostly Honda and Mitsubishi and Chrysler though.Good luck,keep me posted.

SOURCE: Cleaning the Mass Air Flow Sensor

i will try to help. 171/174 indicates lean condition in engine. the mass air flow sensor is located in the rubber tube going to throttlebody. you can try to clean it. using mild carb cleaner safe for sensors, remove sensor from tube. spray clean the tiny wires located in the cylinder. do not touch them, they are very delicate. these engines are also notorious for leaking intake gaskets and faulty pcv valves. these will all set these 2 codes. feel free with anymore questions.

SOURCE: mass air flow sensor bad on 2002 monte carlo ss

It's should be a simple remove and replace. Just make sure the engine is off. Also do not touch any of the filament wires on the sensor, just the plastic housing. Also after you install it drive the car for a little while (city speeds, cruising speeds and inbetween). That way the computer will be able to readjust its setting since it is a new sensor.

SOURCE: 000 NISSAN Xterra -- after warming up, loses RPM by 500-1000..... have replaced ignition wires and distributor, checked mass air flow sensor and OK.....

I had a problem on my Nissan Xterra 2000. Symptons sound similar. In my case, it ran fine for a while and then suddenly the engine starts to stumble and lose output. At one point it did not even have enough HP to move. Irregular idling too. Thought it was water in my fuel. Bought water remover from the store and added to gas tank. Problem did not go away. Instead, "Service Engine Soon" light came on. Had to have it towed to the dealer as there was no way the engine could keep up with traffic. Dealer replaced the "Crank Position Sensor" today. Parts $33.00, Labor: $300 (about 3 hrs worth of work). Seems to work fine now but I will wait and see. Dealer also stated that Distributor bearing appears to be noisy and will need to be replaced sooner or later. I will wait for it to go before I fix that.

Can the camshaft causes the 2002 Mitsubishi space wagon GDI 4g64 not to accelerate over 40 MPH ?


The engine control module is most likely in the limp in mode. This can be caused by a defective engine sensor or the module itself. I would have a diagnostic test done to pinpoint the cause.

Garage replaced O2 sensor TWICE check engine light keeps coming back on


My sister just finally passed inspection with her 2002 Elantra. Same exact problem and the sensor was replaced twice. Here's what you need to do. I know it doesn't make sense but I found it in a tech bulletin. You need to remove the alternator bracket that connects to the block as well as the engine ground and body grounds near the battery. Clean them off with a wire brush and also clean off where they connect to the body of the car. Reconnect them and clear the engine light. My sister's finally passed after that. It did not pass for 2 years until this was done.

I have a 2002 hyundai accent in which the check engine light keeps coming on. I replaced the o2 sensor twice because I was told it was a bad o2 sensor and now the light is on again. any ideas---my...


Thats why you dont take advice from ottozone. First you may really have had an oxygen sensor problem, then you bought one from ottozone, ( who brag about how cheap their parts are) then you put in another cheap sensor. Have your car looked at by well equipped repair shop thats not trying to sell you car parts.
