OBD2P0936
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Hydraulic Pressure Sensor Circuit Intermittent.

Severity

moderateCan drive, but shifting issues may occur and worsen over time.

Summary

P0936 indicates an intermittent issue with the hydraulic pressure sensor circuit in the transmission control system. This can affect how the transmission adjusts hydraulic pressure based on driving conditions.

Symptoms

  • Malfunction Indicator Light (MIL) illuminated
  • Harsh shifting under light acceleration
  • Delayed or soft shifting during hard acceleration
  • Transmission may lock out certain gears

Common Causes

  • Poor connection in wiring harness
  • Water damage to connectors
  • Bent pins in electrical connector
  • Faulty hydraulic pressure sensor
  • Over-sensitive ECM rejecting minor variations in signal voltage

Diagnosis

  1. Check for TSBs related to the issue
  2. Inspect wiring harnesses for damage or water entry
  3. Verify proper voltage and ground at sensor connector
  4. Disconnect LPS and check circuit resistance

Fixes

  • Repair damaged wiring or connectors, replace faulty sensor if necessary

FAQ

What should I do if the MIL is on?

Check for TSBs, inspect wiring harnesses, and verify proper voltage at the sensor connector.
