Throttle Position Sensor/Switch: Description and Operation
CIRCUIT DESCRIPTION
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.
