P0707

DTC P0707 Range SW system A circuit (Low)
DTC P0708 Range SW system A circuit (High)

Circuit description

Shift position is detected by inputting the signal from the neutral start switch ASSY to the transmission control computer ASSY. Engine can start only when the select lever is in P or N position.





Monitor description

These diagnostic codes indicate problems of the wiring harness in the park/neutral position switch and park/neutral position switch circuit.
The park/neutral position switch detects the select lever position and sends signals to TCM.
For safety, the park/neutral position switch detects the select lever position. It is to allow the engine to start only when the select lever is in P or N position.
The park/neutral position switch sends signals corresponding to shift positions (P, R, N, D, or M) to TCM. When receiving 2 or more position signals at one time, TCM determines that the switch or related parts have a problem. TCM turns on MIL and records the diagnostic codes.
