DTC P0850 Park/Neutral Switch Input Circuit

CIRCUIT DESCRIPTION

DTC Detecting 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 the D position.
