Error Code P0932 is defined as Hydraulic Pressure Sensor Circuit. This is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made since 1996 up to the present. Of course, specifications on the definition, troubleshooting, and repairs vary from one make and model to another.

Error Code P0932 refers to a problem with the hydraulic pressure sensor. Hydraulic pressure system works by helping the gear shift in vehicles with automatic transmission. If the vehicle needs to upshift or downshift, the hydraulic circuit associated with the gears will engage or disengage to facilitate the shift. The powertrain control module (PCM) and transmission control module (TCM) controls the hydraulic pressure, which depends on numerous engine factors to determine shift strategy. The PCM also monitors the pressure through the hydraulic pressure sensor.

When the PCM detects a problem with the signal coming from the hydraulic pressure sensor, it registers the Error Code P0932.

Common Symptoms

  • Transmission problems; harsh shifting, inability to shift at certain gears
  • Hesitant acceleration
  • Increase in fuel consumption

Possible Causes

  • Shorted wires, loss of ground, open or corroded cables, blown fuses
  • Faulty hydraulic pressure sensor
  • Defective PCM or TCM (rare)

How to Check

Start the diagnosis by connecting the OBD-II error code scanner to retrieve freeze frame data of the code and other trouble codes. If there are multiple codes present, address the codes in the order they appear on the scanner.

Next, reset the codes and restart the vehicle to see if the code comes back. If the code does not return, the problem is either an intermittent error or triggered erroneously.

If the code comes back, proceed with the diagnosis by inspecting the electrical component system further. Check for any damages on the connectors, fuses, and wires. Repair and replace as needed.

Next, check the ground voltage. If there is no ground found, then proceed on checking the hydraulic pressure sensor.

Make sure to reset the trouble code and restart the vehicle each time you replace a component. This will help determine whether the repair has fixed the problem or not.

How to Fix

  • Repair or replacement of faulty or broken connectors, fuses, and wires
  • Replacement of defective hydraulic pressure sensor
  • Replacement of defective PCM or TCM (rare)

Vehicles with this error code are still drivable, though they may exhibit transmission problems that affect drivability. Continuing to drive the vehicle with this code may lead to more serious issues in the transmission. Thus, it is important to address it as soon as possible.
