Answer 1

Hi there,

The code is for the bank 1 A/F sensor. This is the front O2 sensor, usually mounted in the exhaust manifold. The problem is the computer is seeing to much voltage. This is normally caused by a short in the heater element inside the sensor. usually replacing the sensor will solve the problem.
