P1750 Diagnostic Trouble Code (11 interpretations)

The control module judged the Secondary Pressure Solenoid signal implausible: it stayed inside electrical limits but did not match the value expected for the current operating conditions. This is the manufacturer-specific definition used by BMW.

The control module detected improper operation of the Torque converter clutch (TCC) solenoid/ transmission shift control valve/transmission pressure control solenoid circuit. This is the manufacturer-specific definition used by Dodge.

The control module detected improper operation of the AT - hydraulic system mechanical. This is the manufacturer-specific definition used by Honda.

The control module detected that the monitored Transmission fluid pressure (TFP) - maximum control value reached its permissible limit. This is the manufacturer-specific definition used by Land Rover.

The control module detected that the Transmission shift lever control module - supply voltage stayed below the expected range. This is the manufacturer-specific definition used by Mercedes-Benz.

The control module detected a fault associated with the Voltage Supply Solenoid Valve Pressure Regulators 1 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.

The control module detected that the Steering wheel control information fault is jammed or locked. Documented for the AL4 automatic gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the Gear controls under the steering wheel signal fault was not coherent with related operating data. Documented for the Automated manual gearbox electric control ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected an interruption (open circuit) in the Gear controls at the steering wheel signal fault circuit. Documented for the MCP 6-speed piloted manual gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the Transmission control module (TCM) - supply voltage stayed below the expected range. This is the manufacturer-specific definition used by Audi.

The control module detected that the Power Supply voltage stayed below the expected range. This is the manufacturer-specific definition used by Volkswagen.
