What is the OBDII code on a GMC Sierra?

P0161 is a very common OBDII code that occurs in the GMC Sierra. It is typically caused by a failure in one of the elements that heat the oxygen sensors, specifically bank 2 sensor 2. Replacing the Oxygen sensor will fix the problem a majority of the time.

Where is mil.bank 1 sensor 2 located?

This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 2 is located to the rear of the catalytic converter and should produce an output signal relative to oxygen storage capacity of the catalytic converter. This rear (sensor 2) sensor is less active than the signal produced by the front sensor.

Where is sensor Bank 2 on a GMC?

Bank 2 is closer to the radiator, (also referred to as LH or left hand). UP Refers to Sensor 1 or “front sensor”. It is located closer to the exhaust manifold and before the catalytic converter. DOWN Refers to Sensor 2 or “rear sensor.” It is located after the catalytic converter.

What does the 02 sensor code on a GM Truck mean?

This code basically means that the Bank 2, Sensor 2 (or second o2 sensor back on bank 2) signal voltage is below what is considered normal for that sensor. It’s a four wire sensor being supplied a 0.5 volt reference voltage (usually on the signal wire) and a ground, as well as a power and ground circuit for the o2 sensor heater element.
