Code 55 indicates end of codes. If you are retrieving codes, code 55 will indicated that you have reached the end of the code list. Code 55 will always be reported regardless of if there is another code to report or not. If you don’t receive a code 55 when retrieving codes, the power limited light may be burned out (or you may not have done the code checking procedure correctly). Good work and keep me posted for any other questions you may have.

Hi, these codes relate to your passenger side oxygen sensors. The first thing I would do is check the wiring on these sensors to make sure it hasn't come loose and melted its insulation on a hot pipe. I would also check the connections at the sensors to make sure the connectors are not loose. Repair any suspicious connectors or wires. While under the car, I would start it and check for an exhaust leak at the flage between the exhaust pipe and manifold. Repair any leaks. If all that was good, I would check the wires with an ohmmeter. To do this, disconnect the connectors and check the continuity of each wire from the connector at the sensor to the PCM. Disconnect the battery before taking the connector off the PCM. When testing the wires, there should be zero ohms from one end to the other, and each wire should have infinite ohms to chassis or engine ground. If the wires are all good, I would replace the sensors. Please let me know if you have questions and thanks for using FixYa.
