Engine coolant temperature sensor
Engine oil temperature sensor
Filtered fuel temperature sensor
Left intake manifold air temperature sensor
Right intake manifold air temperature sensor (No 2)
High pressure fuel temperature sensorThe sensor signal for the passive sensors is routed to terminal 1 of each sensor connector. The analog return for the passive sensors is routed from the ECM to terminal 2 of each sensor connector.The following components can cause these codes:
Electrical connector or wiring
Sensor
ECMThe most likely cause of a code is a problem with an electrical connector or wiring. The least likely cause of a code is the ECM.
