A340E (2JZ—GTE) AUTOMATIC TRANSMISSION – TROUBLESHOOTING
Park Neutral Position Switch Circuit
— CIRCUIT DESCRIPTION —
The park/neutral position switch detects the shift lever position and sends signal to ECM.
The ECM receives signals (R, NSW, 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.
