Question

Got the code P0141 on my camry 2002. But it went off after replacing car battery. Does it mean the issue is resolved?

Answer 1

P0141 02 sensor heater circuit malfunction Bank 1 Sensor 2

Just by disconnecting the battery you reset the ECM and cleared the code. To truly know if the code is resolved is by normal driving until the 02 sensor monitors runs. If a fault is detected the CK ENG LT will return. If the 02 sensor monitor runs and clears the issue is resolved.
