P0932 Hydraulic Pressure Sensor Circuit

P0932 indicates a hydraulic pressure sensor circuit fault. The controller cannot trust the hydraulic pressure feedback used for transmission control.

Code details

Generic OBD-II · P0

System: Transmission
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not diagnose pump or valve-body faults until the pressure sensor circuit is verified.

Symptoms of P0932

Harsh, delayed, or slipping shifts, or being stuck in one gear.
Check-engine light, sometimes with limp-home mode.
Flaring RPM or a shudder under load.

Common causes of P0932

Low or degraded transmission fluid.
A failing speed sensor, shift solenoid, or pressure-control circuit.
Wiring, connector, or internal hydraulic/mechanical faults.

Useful checks before replacing parts

Check hydraulic pressure sensor signal, reference voltage, ground, connector condition, and continuity through the transmission harness.
Compare pressure data with commanded pressure, actuator or pump command, gear state, shift timing, and fluid temperature.
Inspect fluid contamination at connectors, internal harness routing, sensor mounting, and related pressure unit or pump relay codes.
