DTC P1780 PARK/NEUTRAL POSITION SWITCH MALFUNCTIONCIRCUIT DESCRIPTION
DTC Detection Condition:
The park/neutral position switch detects the shift lever position and sends signals to the ECM. The ECM receives signals (P, R, N, D, 4, 3, 2 and L) from the park/neutral position switch. When the signal is not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in D position.
