What does code P0054 mean?
Heated Oxygen Sensor
What the P0054 code means. This code means the Heated Oxygen Sensor (HO2S) resistance is out of range with engine bank 1 (side of engine with cylinder #1) on the sensor downstream or behind the catalytic converter.
What to do if your OBD code returns p0054?
If the P0054 code returns, then follow the test procedure: Using the OBD-II scanner, reset the code and test the vehicle again to see if the Engine Warning Light comes back on, and the code returns after the engine is at operating temperature.
What causes a p0054 problem on an O2 sensor?
Potential causes of a P0054 trouble code may include: Burnt, broken, or disconnected wiring and/or connectors A faulty O2 sensor Blown fuse or burnt fusible link Defective engine control relay
What does diagnostic trouble code DTC stand for?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Chevrolet, Ford, GMC, Mazda, Pontiac, Isuzu, etc.). Although generic, the specific repair steps may vary depending on make/model.

How to diagnose check engine light diagnostic trouble code?
To diagnose a P0054 check engine light code we will need to test out the oxygen sensor wiring and also test the circuits through the oxygen sensor itself. The internal processor circuits are a possible cause but are much less likely, so the other areas are thoroughly tested first.
