P2763 Possible Causes
- Faulty torque converter clutch pressure control solenoid
- Torque converter clutch pressure control solenoid circuit open or shorted
- Poor electrical connection in torque converter clutch control solenoid circuit
- Clogged valve body oil passages
How to Fix Code P2763
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
When is the Code Detected?
When the Powertrain Control Module (PCM) detects a short to voltage in the Torque Converter Clutch (TCC) solenoid control circuit, code P2763 is set.
Possible Symptoms
Illuminated engine light (or service engine soon warning light)
Transmission shifting problems
P2763 Meaning
Ignition voltage is supplied to the Torque Converter Clutch (TCC) Pulse Width Modulated (PWM) solenoid. The Powertrain Control Module (PCM) controls the TCC PWM solenoid on and off times by controlling the ground side of the TCC solenoid control circuit. The PCM uses a PWM duty cycle to control TCC application and release. When the solenoid is commanded OFF, the PCM detects high voltage. When the solenoid is commanded ON, the PCM detects low voltage.
