What this code means

Torque Converter Clutch Pressure Control Solenoid Control Circuit High.

P2763 is a generic code: it means the same thing on every make. P2763 belongs to family P27xx — Transmission. Its page explains how to read a code and groups all its codes by part.

Type of fault

The control unit reads a voltage on this circuit above its expected range. Usual causes: a broken wire or a poor ground, a short to a supply voltage, or the component itself. As with a low signal, check the wiring and connector before the part.

Torque converter lock-up clutch

The torque converter links the engine to an automatic gearbox through fluid. At steady speed, a clutch locks it to avoid slipping and save fuel. The control unit engages it with a solenoid and checks that the engine speed matches the gearbox speed.

What you notice

Engine speed slightly too high at steady speed, higher consumption, shudder as if driving over rumble strips, or the engine stalling when stopping if the clutch stays engaged.

How to check it

Check the fluid level and condition, then the lock-up solenoid's connector and resistance. At steady speed in top gear, Klaro's engine speed should drop by a few hundred rpm when the converter locks.

What to do

Have it checked this week. The car remains usable, but the fault will not clear itself and will fail the roadworthiness test.

Clearing a code switches the light off but repairs nothing: if the fault remains, the code comes back. Clearing a fault code yourself →
