Go to an auto part store and have them read the codes with their code reader to get "P" codes. I have no clue how you got that code and don't trust it for diagnosing your vehicle.They scan for codes for free.Source(s): Mitsubishi Master Tech

No power or signal from the O2 sensor.

You will need to check O2 sensor operation with a scanner. Check O2 sensor heater resistance. Check O2 sensor heater wiring integrity with a test light with a scanner with directional control capability. O2 sensor could be bad or there is a wiring problem.
