HELP - dont know what this code means!
 

Hello. I just recently replaced a couple things on my car that were throwing codes. I hooked up the vag com that i got working today for the first time and cleared the codes. The things i replaced were the front (pre-cat) o2 sensor, and an ignition coil (which wasnt actually bad, it had just popped up.)

I didnt get a check engine light until i started the car back up again. The code this time, i cant find anything on this one and dont know what to do. Perhaps you can help me, i have searched all around but dont know...


P1118 O2 Sensor Heater Circ.,Bank1-Sensor2 Open


I just replaced this sensor. How would I use VAG COM to log it and see what it is doing? Any help would be appriciated. Thanks.

Anybody? Cincy?

Did I stump everybody?

RE: HELP - dont know what this code means!
 

its either the mass air flow or the after cat o2.

real stumper.....

RE: HELP - dont know what this code means!
 

Thr after cat o2 is disabled, or blocked, using the apr testpipe program. I am running a cat again but decided to leave the program on there... one less o2 sensor to worry about. Why would this be a MAF? I replaced that as well!... I dont noticed a power loss at all, like i did before when the MAF took a crap.

RE: HELP - dont know what this code means!
 

the post cat sensor needs replaced.

the testpipe file just eliminates the cat below effeincy code, thats all.

Why would both my o2s need replaced? Could it be from running seafoam through my car? I am thinking that after blowing out all that smoke it might have killed both my o2 sensors. How sure are you cincy? (why do i question you? lol)

RE: HELP - dont know what this code means!
 

could of been the seafoam, you may have used just a tad to much. And im sure it needs replaced.

btw, the code is p1116 not 8

RE: HELP - dont know what this code means!
 

VAG COM told me it was p1118. I am sure of that.


P1116 O2 Sensor Heater Circ.,Bank1-Sensor1 Open

Different o2 sensor. Sure I should replace the post cat? (Want to confirm before i spend $65)

RE: HELP - dont know what this code means!
 

just looked up the code again and it is listed both as p1116 and 8. Not sure if years have differnt codes or what, but both have the same "O2 Sensor Heater Circ.,Bank1-Sensor2 Open" with it

RE: HELP - dont know what this code means!
 

look to the mass air if the voltage levels are correct for the post cat o2.
