U340E AUTOMATIC TRANSMISSION / TRANSAXLE AUTOMATIC TRANSAXLE SYSTEM P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input)
DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.

D input signal ·
2 input signal ·
L input signal (C) All switches are OFF simultaneously for P, R, N, D, 2 and L positions (2-trip detection logic) (D) Both 1 and 2 are met (2-trip detection logic) 1.
One of following is met 1.
NSW input signal 2.
P input signal 3.
R input signal 4.
N input signal 2.
One of following is ON. 1.
3 input signal |

MONITOR DESCRIPTION
The park/neutral position switch detects the gearshift position and sends a signal to the ECM.
For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the shift lever is in P or N.
When the park/neutral position switch sends more than one signal at a time from switch positions P, R, N, D, 3, 2 or L the ECM interprets this as a fault in the switch. The ECM will illuminate the MIL and store this DTC.
