What does a p0156 code on a PCM mean?
The o2 sensors are very important for the proper operation of the engine. Innacurate or faulty o2 sensors can cause the PCM to add or take away fuel based on the faulty o2 sensor voltage which can cause a host of problems. A P0156 code refers to the Bank 2,2 o2 sensor or the downstream (post-cat) o2 sensor on Bank 2.
What causes a p0156 code on an O2 sensor?
Potential causes of an P0156 code include: 1 Bad O2 sensor 2 Signal shorted to voltage 3 Wiring problems due to contact with exhaust components 4 Holes in exhaust near o2 sensor
