Code P1755 Description
The Transmission Throttle Valve Actuator (TTVA) does not require any mechanical adjustments. All changes in throttle valve position are controlled by the Engine Control Module (ECM).
The TTVA does require an initialization period after the actuator has been removed or replaced. After the actuator has been removed or replaced, move the ignition to the ON position for thirty (30) seconds. This will allow the ECM sufficient time to perform the internal calibration procedures to learn the TTVA's current zero position.

- Faulty Transmission Throttle Valve Actuator (TTVA)
- Transmission Throttle Valve Actuator (TTVA) harness is open or shorted
