Code 95, Change Oil Light: Notes
PCM monitors driving conditions and determines when to turn on change oil light. Maximum possible mileage accumulation is 7500 miles; however, PCM may turn on light sooner depending upon driving conditions (i.e. temperature and engine load history). Code will set and PCM will turn on light if wrong monitored voltage is present on light circuit for 26 seconds or more. PCM will not turn on SERVICE ENGINE SOON light.
- Unplugging PCM will determine if circuit is shorted to ground or if PCM is at fault.
