P2096, P2098 Fault codes


Recommended Posts

My friend's 2002 ROW C2 Manual Cab had its CEL come on yesterday evening. On my fault code reader, it read P2096 and P2098 which is the Post Catalytic Fuel Trim Bank 1 and 2 System Too Lean code respectively. It would be pretty unlucky to have both lambda sensors fail together especially only 1 year and 10000 miles ago he had all 4 replaced by the Porsche centre. Could it be the MAF? I've cleared the code and it hasn't returned so far.

Also, on the same day he was driving, the interior lights came on by themselves and then later when he parked the car, as he was walking away, the roof folded itself. Obviously not good on the street. Its now done that twice. All control units under both seats are dry. Any ideas?

My information comes from the Porsche DME 7.8/OBD II service manual for MY2002 996 Carrera.

Where are you getting your information?

Its from the fault code reader. I should have looked up the service manual that I have to cross-check the code. Just goes to show how lazy one can become when presented with tools that give you extra features like code definitions. Doesn't mean that they are always right.
