What Does P0932 Mean?
The PCM or TCM has detected a fault in the hydraulic pressure sensor circuit. This sensor measures the hydraulic pressure within the transmission or power steering system and provides critical feedback to the control module. A circuit fault means the control module cannot read the pressure value, which impairs its ability to properly manage hydraulic system operation and adapt to varying load conditions.
Common Causes
30%
Faulty hydraulic pressure sensor with degraded internal circuitry
25%
Open or shorted wiring in the hydraulic pressure sensor circuit
20%
Corroded or damaged connector at the pressure sensor or control module
15%
Poor ground connection for the pressure sensor reference circuit
10%
Control module internal fault on the sensor input circuit
Diagnostic Steps
1
Check the hydraulic pressure sensor connector for corrosion, bent pins, or water intrusion; clean and reseat the connector.
2
Measure the voltage on the pressure sensor signal wire at the control module connector with the key on; compare to the expected range (typically 0.5V to 4.5V for a 5V reference sensor).
3
Verify the sensor has proper 5V reference voltage and ground by measuring at the sensor connector with it disconnected from the sensor.
4
If the reference voltage and ground are present, the sensor itself is likely faulty; measure its resistance or output through its operating range if accessible.
5
If voltage readings are normal at the sensor but abnormal at the control module, check for wiring damage between the two points.

The most common cause of P0932 (Hydraulic Pressure Sensor Circuit) is: Faulty hydraulic pressure sensor with degraded internal circuitry
Typical repair costs for P0932 range from $150 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Without accurate hydraulic pressure feedback, the control module may apply default pressure values that could result in harsh or soft shifts, and it cannot detect low-pressure conditions that would warn of impending hydraulic failure.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0932 to identify the root cause.
