Insufficient Coolant Temperature for Stable Operation, Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature). ETAX RPM pulse generator signal for Misfire detection does not correlate with expected value. It is the only time the PCM output voltage can be controlled using the P1389 without the use of an auto shutdown feature (ASD). Energizing Heated Air Intake does not change intake air temperature sensor an acceptable amount. Injector # 6 output driver stage does not respond properly to the control signal. Leak Detection Pump Sw or Mechanical Fault. PCM error P1696. By incorporating an OBD-II port, which was introduced on January 1, 1996, almost all of the engine controls in cars built prior to January 1, 1996 are provided. Within the last 50 starts, the majority of them have been successful. Mark helpful 30 Guru92PWHC answered 6 months ago I found a ground short.
