Transmission Control System

P1780 - Park/Neutral Position Switch Malfunction

CIRCUIT DESCRIPTION

DTC Detection Condition:

The park/neutral position switch detects the shift lever position and sends signals to the ECM.

The ECM receives signals (NSW, R, 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.
