P0962: Pressure Control Solenoid “A” Control Circuit Low OBD-II Trouble Code

Every time your transmission changes gears, the ECU has to increase or reduce the hydraulic pressure inside the transmission, that way the shifts aren’t too hard or soft. If there is a low voltage signal on the pressure control solenoid A circuit, the ECU may not be able to command the solenoid properly. This will result in a P0962 DTC being saved.

How Serious is the Code?

If your vehicle has a P0962 diagnostic trouble code, you will likely experience a number of drivability issues that include slipping, unusually harsh shifts, and the engine could stall unexpectedly.

Symptoms

Symptoms of a P0962 include:

  • Slipping between gears
  • Harsh shifts
  • Transmission overheats
  • Engine stalls
  • Engine misfire-like symptoms
  • Limp mode

Causes

  • Transmission fluid and filter are dirty
  • Wiring damage
  • Broken or corroded connectors
  • Pressure control solenoid has failed
  • Transmission pump is failed
  • Valve body failure
  • TCM/ECU problems

How to Diagnose the Code?

The first step to figuring out what is causing a P0962 OBDII trouble code, is to see if there’s enough transmission fluid in the gearbox. If the transmission fluid is dirty or low, the transmission should be serviced. If there are no issues here, then the wiring and connectors along the transmission wiring harness should be inspected for signs of damage and corrosion. Beyond that, further mechanical diagnosis may be needed to determine if the problem is caused by a faulty pressure control solenoid, transmission pump, valve body or ECU/TCM problems.
