P0750 on Citroen
Shift Solenoid A Malfunction
P0750 on Citroen vehicles indicates shift solenoid a malfunction. Au7o has documented this code across 1 Citroen model — most commonly on C3. This code indicates the transmission control system detected a malfunction in shift solenoid 'A', one of the electrically operated valves that direct hydraulic fluid to engage gears. The computer commands these solenoids to control upshifts and downshifts, and it monitors their circuits and the resulting gear changes. When solenoid A doesn't respond electrically as expected — or the resulting shift doesn't happen correctly — this code is set. You may notice harsh, delayed, or missing shifts, or the transmission may enter a fail-safe (limp) mode. Typical repair costs on Citroen range from $600 to $3,000, depending on the specific model and root cause.
Common Causes of P0750
- •Failed or stuck shift solenoid A
- •Open, shorted, or chafed solenoid wiring
- •Corroded or loose transmission connector
- •Low, dirty, or degraded transmission fluid
- •Clogged solenoid or valve body passages
- •Internal valve body or hydraulic fault
- •Faulty transmission control module (TCM)

Citroen C3(1 issue)
- SensoDrive/EGS/ETG Automated-Manual Gearbox and Clutch Actuator Failure2003-2016
C3s fitted with Citroen's automated-manual gearboxes — SensoDrive on the C3 I, then EGS6/ETG6 on later e-HDi and PureTech cars — suffer well-documented failures of the electronic clutch actuator, gear actuator and gearbox ECU. Worn actuator motors and clutch-position adaptation errors cause violently jerky gearchanges, refusal to select gears, gearbox warning messages with the box locked in gear (limp mode), and in some ECU failures a car that will not start. Specialist rebuilders describe the actuator and ECU faults as inherent design weaknesses, and repairs at a dealer can run from several hundred to several thousand pounds.

What does P0750 mean on Citroen?▼
P0750 stands for "Shift Solenoid A Malfunction." This code indicates the transmission control system detected a malfunction in shift solenoid 'A', one of the electrically operated valves that direct hydraulic fluid to engage gears. The computer commands these solenoids to control upshifts and downshifts, and it monitors their circuits and the resulting gear changes. When solenoid A doesn't respond electrically as expected — or the resulting shift doesn't happen correctly — this code is set. You may notice harsh, delayed, or missing shifts, or the transmission may enter a fail-safe (limp) mode. On Citroen specifically, this code is documented across 1 model.
