DTC P0751 Shift Solenoid "A" Malfunction (Shift Solenoid Valve S1)

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 trouble of the shift solenoid valves and valve body.

HINT: Check the shift solenoid valve No.1 when DTC P0751 is output and check the shift solenoid valve No.2 when DTC P0756 is output.
