wiring problem on gsi dont know what else to do
been having lambda sensor faults come up on bank 1 sensor 1 for a few mth ive bought 2 universal sensors still getting faults so i bought a second hand one still got faults so bite the bullet and bought a proper one and still got fault codes
so took it to paulvectrac as i thought it could be the plug on the loom which connects to sensor paul soildered a another plug on for me (thanks paul for the help) but still fault code (spanner light) and after a little time the eml light comes on
i havent a clue where to go from here
when ive had it linked up to the computer ive noticed the o2 sensor bank 1 sensor one runs at 469mv even when i rev the car and is constantly running rich.
where bank 2 senor one changes from 469mv up to around 700+ and down to 300mv when i rev and is constantly changing from lean to rich
Q1, do the 3.2 gsi have a fuel/air ratio for each bank of cylinders that could be changed
Q2, does anyone think buying a new engine loom could fix the problem and where could i buy one from and how much
Q3, anybodyelse had this problem
thanks to paul who managed to release the o2 sensor on bank 2 for me i couldnt get it undone
im going to swap bank one to bank 2 to see if the fault stays on the same sensor which will also tell me it could be wiring or another part which is causing the 02 sensor to give a fault code any help would be greatful
just to add car run ok with the fault use a bit more fuel but im worried as im sure it will be affecting the cat running rich all the time
