Powertrain Codes

P0755 - MAZDA - Shift Solenoid 2 Circuit failure

Symptoms

- Engine Light ON (or Service Engine Soon Warning Light) - Transmission will not shift gears.

Possible Causes

- Low transmission fluid level - Dirty transmission fluid - Faulty shift solenoid 2 valve - Shift solenoid 2 valve harness or connectors - Shift solenoid 2 valve circuit is open or shorted

When Detected

The P0755 code is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.

Description

Shift solenoid valve 2 is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position.
