A friend is having trouble with his astra H. 1.9cdti engine Z19DTH
He has been getting intermittent limp mode, and reports the ABS light and TC lights come on at the same time as engine MIL.
I've tested the car a few times myself, but have not been able to get it to fault during my testing.
First time I plugged in, there where absolutely no stored codes in ECM, with TEXA, opcom, autel, EOBD, nothing.
After the next time it went wrong I got, P1120 AND P1122 from ECM. Along with C0237 AND C0242 from ABS.
I'm having difficulty nailing down the correct description for P1120 AND P1122, Op-com says APP sensor, but other sources are saying TPS.
Has anybody got a 100% accurate description?
