DTC P0761 Shift Solenoid "C" Performance (Shift Solenoid Valve S3)

SYSTEM DESCRIPTION

DTC Detecting Condition:

The ECM uses signals from the vehicle speed sensor and input turbine speed sensor to detect the actual gear position (1st, 2nd, 3rd, 4th or 5th gear). The ECM then compares the actual gear with the shift schedule in the ECM memory to detect mechanical trouble of the shift solenoid valves, valve body and automatic transmission (clutch, brake or gear etc.).

P0761
The ECM commands transmission gearshifts by turning the shift-solenoid valve "ON/OFF". Using the signals from the Input Speed sensor (Input shaft speed) and the Output Speed sensor (Output shaft speed or Counter shaft speed), the ECM calculates the actual gear position (1st, 2nd, 3rd, 4th, 5th, or 6th gear position). When the gear position indicated by the ECM and the actual gear position are not the same, the ECM illuminates the MIL and stores the DTC.
