P0932: Hydraulic Pressure Sensor Circuit OBD-II Trouble Code

An automatic transmission changes gears by utilizing pressurized hydraulic fluid/ATF to move transmission parts like valves and gearsets. Different driving conditions require different amounts of pressure, and that pressure is monitored by the transmission hydraulic pressure sensor (a.k.a. transmission line pressure sensor). If the ECU detects a problem with this sensor, a P0932 DTC will be saved.

How Serious is the Code?

The ECU has to know how much hydraulic pressure is currently available inside the transmission, that way it can adjust the shift pattern accordingly. If this information is not available through the hydraulic pressure sensor circuit, a P0932 diagnostic trouble code will be triggered.

Symptoms

Symptoms of a P0932 include:

  • Unusually harsh shifting at low RPM
  • Unusually soft shifting at higher RPM under load
  • Poor acceleration (because the transmission starts in a higher gear)
  • Increased engine RPMs at speed (cause hired gears are locked out)

Causes

  • Damaged wiring or connectors
  • Bad fuses
  • Bad transmission pressure sensor
  • ECU/TCM issues

How to Diagnose the Code?

The P0932 OBDII trouble code is a general electrical fault, so the diagnosis process should begin by checking the wiring and connectors for signs of damage and corrosion. Any fuses or relays related to this circuit should also be checked, along with any ground contacts/wires. The transmission pressure sensor itself may need to be tested, and the ECU and TCM programming may also need to be considered.
