2003 Olds Engine Light

Have a 2003 Olds Silhouette. The engine light came on so a friend of mine scanned it and we got p141

Can anyone tell me what that is and how to fix?

Thanks

A smoke test will pin point any unmetered air leaks.

PO141 is an Oxygen sensor heater circuit malfunction (downstream sensor)

This points toward a wire heating problem within the circuit on the O2 sensor inserted into the exhaust system after the catalytic converter.

This does not mean the O2 sensor needs replacing. There is a test that is performed to ensure the system is correct or not.

Thanks guys.

Since reading the code, and reseting it, the code has not come back.

Will wait and see what may happen.
