at first my 2001 grand jeep cherokee Ltd had an overheating problem. The electrician claimed that the fan hydrolic switch may be faulty. He fixed the overheating problem by bypassing the fan hydrolic switch. Consequently the oxygen sensor light went on. After about 10 days the car is stalling and misbehaving. I suspect that the car electrician may have done something with the wiring system. I am not stucked with a stalled car and can't find a jeep specialist as I am in a remote city in West Africa. Please advise

 

Welcome to CF.

Check the fuses , o2 sensor has it's own fuse.

 

Take the negative from battery off for 10 sec and put it back. That my reset your fault code in computer.
