Torque Converter Clutch Circuit Short to Battery or Open |
While the vehicle is being driven so that lock-up is requested, a short to +B or open is detected in the solenoid (SL) valve circuit (2-trip detection logic). |
| Comes on |
DTC stored | SAE Code: P2770 |
MONITOR DESCRIPTION
Based on the signals from the throttle position sensor, the air flow meter and the crankshaft position sensor, the ECM sends a signal to solenoid (SL) valve to regulate the hydraulic pressure and provide smoother torque converter engagement. Solenoid (SL) valve responds to commands from the ECM. The valve controls the lock-up relay valve to perform the torque-converter lock-up function. If the ECM detects an open or short to +B in the solenoid (SL) valve circuit, it will illuminate the MIL and store the DTC.
