OBD2 P0969

OBD2P0969
Diagnostic Trouble Code· Standard OBD-II fault code read from the vehicle's onboard diagnostics.

What it means

Pressure Control Solenoid 'C' Control Circuit Range/Performance.

Severity

highThe vehicle may still be drivable, but shifting issues and potential damage to the transmission can occur if not addressed.

Summary

Code P0969 indicates an issue with the electronic pressure control solenoid 'C' in your vehicle's automatic transmission system. This code is related to problems with the solenoid or its circuit, affecting how the transmission regulates hydraulic pressure.

Symptoms

  • Delayed transmission engagement
  • Erratic shifting behavior
  • Transmission failure to shift gears properly
  • Harsh gear shifts
  • Loud whining noise from the torque converter/bell housing area

Common Causes

  • Open or shorted wiring/connectors in the EPCS circuit
  • Defective electronic pressure control solenoid 'C'
  • Transmission pump failure
  • Low or subpar transmission fluid

Diagnosis

  1. Inspect transmission control wiring and connectors for any visible damage or loose connections.
  2. Check the transmission fluid level and condition. Replace burnt-smelling or low fluid.
  3. Use a diagnostic scanner to retrieve all stored codes and freeze frame data.
  4. Test pump pressure using a transmission pressure gauge if fluid levels are normal.
  5. Disconnect controllers before testing circuit resistance with a digital volt/ohmmeter (DVOM).

Fixes

  • Replace the defective electronic pressure control solenoid 'C' or repair faulty wiring/connectors in its circuit.

FAQ

What should I do if my transmission fluid is low?

Refill the transmission with the recommended fluid and test drive to see if the problem persists. If the code resets, further diagnosis may be needed.

Can a P0969 cause damage to other parts of the vehicle?
