1. DTC

description:

DTC P0707 Shift level position sensor (gear switch): low voltage

DTC P0708 Shift level position sensor (gear switch): high voltage

The gear switch assembly provides gear shifting position data to the transmission control unit (TCU). When the
gear switch is not in position P or N, the system will prohibit the operation of the starter. When putting into the
gear R, the backup lamp circuit accesses. The shift switch has independent circuit with respect to the above
function. The above function can only normally operate after the circuit is correctly connected with the TCU.

The transmission control unit provides a 5V reference signal to the gear position control circuit (gear switch) to
measure the voltage of the circuit and thus determine the position in which the gear is in. The resistance value in
different shift positions is different.

4. Diagnostic

procedures:

Note: Before carrying out this diagnosis step, observe the data list on fault diagnosis tester and analyze the
accuracy of the data, as these will help with quick diagnosis.

1

Read the fault code again after clearing away the fault code to check if fault codes, except DTC
P0707 and P0708 exist in the control system.

A. Connect fault diagnosis tester to the datalink connector.

B. Rotated ignition switch to ON position

C. Switch on fault diagnostic device power supply

D. Clear DTC code.

E. Reset reading fault code, and check if DTCs meet setting condition of fault code in current

Detect the resistance of shift level position sensor (gear switch) under the state of each gear.

A. Turn the ignition switch to the OFF position.

B. Change the shift gear to the “P”, “R”, “N”, “D”

and “M” positions in order to measure the
resistance between Terminals 4 and 5 of the
harness connector J-5 of the gear switch.
