MIL has come on. OBD reader shows oxygen sensor problem. I’ll check the wiring but looks like a new sensor (s) needed.
Engine is a 4litre with Gems management. Sensors before and after the cats. Anyone know the sensor part number in case I need to replace. Engine is running ok and it looks like the post cat sensor is the cause. Fluctuating voltage seen on live running check. Hoping it is the sensor not the cat itself ( or both £££
Fault code is P1193. Possibly sensor heater issue.
Cold start and no light. Light on a few miles down the road when things have warmed up.
