The P0102 is a maf code the other four are heated 02 sensor ground fault codes. Does anyone know where the fuse is for these? I'm still reading but haven't found much about it yet.

Will CRC maf cleaner destroy the MAF or is it worth trying to clean? Hrmmm...

P0102

P0057

P0037

P0031

P0051

After some searching I'm not finding anything specific to the W8 but other models are saying the o2 sensor is on the same fuse as the fuel pump, and that if the wiring harness gets wet it can cause the fuse to blow. Although my car is running fine.

I cleared the codes, and the motor was fluttering on the first start up, i.e. the revs wouldn't level out. I took it across the street to fill up and it purred smooth that time, ran her hard for about an hour and still seems to be running fine. Got 25mpg average at 60mph so if the maf is fouled it's working purty damn good.

On inspection of the intake I noticed one of my clamps on the air box is missing *yay* and the wiring harness for the maf was loose. I secured all of it the best I could.

Discussion on similiar issue

Checked fuse seems OK it is a 10amp fuse I'll look around see if I have another.

After clearing the codes and a trip down the road the mil light came back on. P0102 again. But, no O2 heater codes. I've purchased a can of CRC MAF Cleaner


Any thoughts are always appreciated.

PEACE
Alex

re: CRC MAF Cleaner... can't hurt. I did mine on the weekend. For the two screws that hold the MAF sensor in its housing, you'll either need the proper 5-lobe security bit (it's not Torx), or do what I did and use a dremel to cut a slot in the screw head so you can use a flathead screwdriver.

Give it a good soak all over, and let it dry thoroughly before re-assembly. Doesn't take long.

Yea I thought that was just a torx security bit, I have a set of drivers for those, but it's not a torx bit. Go Figure. Hoping to have enough time to do this today. Will report back.

I had a P0102 MAF code in my old 2001 V6 4motion.
Dealer said to replace the MAF. I bought a brand new one and installed myself: no fix.
Previous owner had cut (?!) the wires for 2 of the O2 sensors causing codes.
Since I could never fix the MAF code it is my opinion that the O2 sensors were effecting the MAF.
Got rid of that car because fixing the sensors would cost more than i paid for the car.

Hope you get it fixed...

It's possible, haven't got a chance to clean the maf yet. As far as I can tell the O2 sensor code is gone.

Well the CEL light shut off the other day on it's own, I never did get a chance to use that CRC cleaner yet. I had the oil and air filter changed. Turned out the old air filter had been jammed into the airbox leaving the fins all F*d up.

This is like the 3rd time my car has seemingly "fixed" itself, clever girl.

Well, I noticed smell of gas after the fuelpump install and shrugged it off as... spilt or something.

It's still there and very strong on a refill. I've been told the mechanic is a good guy and will honor his work. I'm just wondering if anyone would have any thoughts on a place to look.

No gas is leaking, no wet lines, just fumes. Smell dissipates after about a half a tank.

Going to use this as a bump, and a woohoo post.

So left a library today, car was shaking, bad at idle. Pulled out and I thought it was going to stall. sh*t sh*t sh*t was all I could think, I had to travel 33 miles with no cell coverage and no money.

34 tedious minutes later I arrived at an Advanced, borrowed the scanner and boom there is the p0011 Bank A....

Started the car back up , and smooth idle.

Everything went better than expected.


But hey, I still haven't gotten back the mechanic about the gas fumes anyone have a word of wisdom about replacing fuel pumps and then clogging a vent or something?
