Where is the heater control sensor & heater oxygen sensor

Question

Where is the oxygen sensor & heater control sensor located?

Answer 1

Hi there,

Both of these codes are for the Bank #2 O2 sensor, #1 sensor.

This is located ahead of the catalytic converter on the passenger side of the vehicle. Either in the exhaust manifold or in the exhaust pipe ahead of the converter. Generally it means the heater circuit inside the sensor is no good and replacement will generally resolve the problem.
