    My 2008 Jeep grand Cherokee engine light keeps coming on. The engine was scanned and code for O2 sensors kept coming up. The O2 sensor bank one was replaced and the O2 sensor bank two has been replaced twice. Now the light has come back on again. I have a feeling it’s going to read 02 sensor again. Is this a computer issue?What do you think?

    Welcome @Dan ....using OEM quality O2 sensors? check connections? any cu anti-seize on the sensor tip? Auto parts stores like Advance/Autozone can scan for codes

    It was brought to a mechanic who replaced the sensors. I don’t want to back a third time for them to tell me it’s an O2 sensor again.

    Well the shop should remedy the problem if its within the warranty period. If it's the O2 sensor again triggering the CEL changing the O2 sensors ought to be super ez since they won't be extremely rusted or welded on.
