What is the P0965 Fault code? What does it all mean?

If the powertrain controller module (PCM), receives an invalid voltage signal from “B” the transmission pressure control solenoid, it will set a malfunction code of P0965.

Automatic transmissions typically have three pressure control solenoids A, C, and B. Newer transmissions have more solenoids but more gears. P0965 fault code B is related to the pressure controller solenoid circuit. If this code is set on your vehicle, it could be due to a problem in the solenoid, sensor, wiring, transmission, or both.

Hydraulic pressure is needed to move the clutches and gears in the transmission. This pressure is controlled by the PCM using tiny components known as pressure control solenoids. The solenoids are responsible for adjusting the fluid pressure in order to maintain smooth operation and smooth shifting. The PCM monitors and controls the fluid pressure in the solenoids. It then directs fluid to different hydraulic circuits which change the transmission gear ratio as required. A P0965 fault code will be stored if the pressure control solenoid B is not functioning properly. Other transmission problems can occur, such as difficult gear changes.

Only vehicles with an automatic transmission will have this code. There are many models that are susceptible to the P0965 fault code, including Opel, Suzuki and Opel as well as Opel, GMCs, Chevrolets, Honda, Opel, Suzuki, Opel, Opel, Opel, Opel, Opel, Opel, Opel, Opel, Opel, Suzuki, Opel, Opel, Opel, Honda, GMCs, Chevrolets, Honda, Opel, Saturn, Land Rovers, Acura, Ford, Ford, and Opel.

What is the P0965 Fault Code?

Below are some reasons to set fault code P0965:

  • – The pressure control solenoid “B”, shorted, opened, damaged, fused wires or loose connectors
  • – Defective pressure control solenoid
  • – Missing or dirty transmission oil
  • – Blockage of transmission filter
  • – Defective transmission pump
  • – Congested transmission fluid passages
  • – Defective PCM / TCM (transmission control module)

 

What are the symptoms of the P0965 Fault code?

You may experience the following symptoms if your vehicle has the code P0965:

  • – Illumination for the check engine light
  • – An increase in fuel consumption
  • – Gearbox overheating
  • – Gear shifting during gear changes
  • – Difficulty shifting gears
  • – Misfire-like symptoms
  • PCM can reduce vehicle speed and enter safe mode

 

How do I fix the P0965 fault code?

Depending on the reason for the fault, the P0965 fault code repair procedure may differ. Other codes that are associated with this code should also be repaired. There are several repairs that could fix the problem.

  • Repair and replacement of damaged, burnt, or broken wiring and connectors that are connected to the “B” pressure control solenoid
  • – Check the transmission fluid and replace any that is missing or dirty.
  • – Clean the transmission filter
  • – Cleaning the transmission and repairing fuel lines that are clogged
  • – Repair or replacement for a faulty transmission pump
  • – Replacing a defective pressure control solenoid
  • – Resolving TCM or PCM related problems

If the fault has not been corrected, you should drive the vehicle for at least 20 second at 40 km/h to verify. If repairs fail, the code is returned.

 

How serious is the P0965 fault code?

Although this code is moderately severe, if it isn’t addressed promptly, the severity will rise and the vehicle could become undriveable. This can cause internal damage to the transmission. It’s best to get your vehicle repaired immediately if you find P0965.
