First off I have a euro engine map based car. I also have a code for error in MAF or VAF ? Seeing as I dont have a maf im extra confused. Here are the codes , 102, 134, 135. Now 2 of these are for front o2 sensor and didnt come on untill I installed my rear o2 sensor. The other one is the maf vaf code. A little help would be much appreciated

Thanks

Pleeeeese help!

 

remove the rear o2 sensor and plug the hole. Remove the MAF, clean it with electronics or MAF cleaner, then disconnect the battery for 1 minute.

 

Yeh the issue is <u>I DONT HAVE A MAF!!!!</u> Its a euro based MAP engine, I need someone with like a Euro Alldata to tell em what the hell that code is for.

 

Have you reset your ECU?

Regardless of MAF or no MAF, the problem is on the ECU pin 41, or the wiring harness that would go to the MAF.

 

I reset the ECU after getting a new rear o2 sensor, this code came up aswell as a error in the front o2 sensor.

 

I take it you're running a header on your car. The lack of catalytic converter will cause the 2 other faults. The MAF fault is your only real fault.

Have you changed your ECU?

Check around this wiring harness for wires which look like they could be shorting to ground.

I have a cat, My Emissions is good, I DONT HAVE A MAF, I dont have that piece on my intake piping at all.

 

^^ I realize this. Look at the wiring harness. Look at the ECU.

Is your catalytic converter before or after the 2nd o2 sensor?

The MAF wires are most likely either hanging and terminated or tucked away inside the harness.

The cat is before the 2nd o2 sensor, I dont have a cat code, Im getting a code saying my front o2 sensor isnt reading.

Oh no... Well this doesn't make any sense at all, I decided to take a look at my map sensor because of this whole thing. Their isn't one... I am amazed confused and worried all at once, My car has been driving great I have been getting good gas mileage and this doesn't add up.

 

The MAP is on the manifold. The MAF would be on the intake.

I looked at the codes, one is for the front(bank1, sensor 1) the other is for the rear (bank1 sensor 2) Why did you have your rear o2 sensor off?

I think your problem is at the ECU.... It's possible you kicked the connector or something.



The pins that are effected are pins 39,40 and 41.
