T4 fault codes - help!

ctsracing · Sep 24th, 2008, 20:56

Hi all,

Was filling the car up last Saturday, and when restarted the car to leave, the engine mgt light came on. Decoded and reset codes when I got home, and all seems fine. However, just wondering if there should be anything I need to change for these:

P0138 - 02 sensor, high voltage bank 1 sensor 1
P0172 - System rich, bank 1
P0335 - Crank sensor (this was replaced early this year, so should be fine?)

Is there a common link between these, and if so what should I be looking at changing?

Any help greatly appreciated

Dave

ike the car is running rich from the first two codes so my gues is its the crankshaft sensor again. Is the engine running lumpy on tickover?

Engine seems fine on tickover, both when intially starting the engine and if returning to idle when running.

I will unbolt the sensor and give it a clean, and check no gunk or anything there that could be affecting it! Strange it's only ever when re-starting the car, if stopped for fuel, or the car didn't engage on the first attempt, that the light would come on...

Many thanks.
