Answer 1

Hi there

The sensor may not be the actual problem. With this code you have to check and make sure there aren't any reasons for the system to be lean on that bank. Intake manifold gasket or a bad mass air flow sensor can cause this. Also, if you have an exhaust leak before the front O2 sensor you can get this code.
