Few weeks ago, my service engine soon light came on. Brought it to the mechanic and found it was the P0146 error code. Found and replace a faulty oxygen sensor and rear cat converter with flex pipe. They also checked the wiring harness and found no
problem. While driving the car, the service engine soon light came back on and is still on. My mechanic suspects the ECM module. Is there any way to verify this and how do I fix this issue. Thanks
