P0750

SYSTEM DESCRIPTION

DTC Detecting Condition:

The ECM uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D gear).

Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical troubles of the shift solenoid valves and valve body.

HINT:
- Check the shift solenoid valve SL1 when DTC P0750 is output.
- Check the shift solenoid valve SL2 when DTC P0755 is output.
- Check the shift solenoid valve S4 when DTC P0765 is output.
