If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to the p0965 fault code.

  • The symptoms of the automobile fault code P0965 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p0965 can be caused by a faulty Pressure Control Solenoid ‘B’, an open or shorted harness, or a poor electrical connection in the circuit.

  • The fault code P0965 can be caused by: a faulty Pressure Control Solenoid ‘B’, an open or shorted harness for the Pressure Control Solenoid ‘B’, and a poor electrical connection in the circuit of the Pressure Control Solenoid ‘B’.

To fix the p0965 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p0965, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • The estimated repair time for this fix is 1.0 hour.

The factors influencing the diagnosis and fixing cost of the automobile fault code p0965 are the estimated repair time of 1.0 hour and the typical auto repair shop charges of $75 to $150 per hour.

The P0965 fault code refers to a problem with the Pressure Control (PC) Solenoid Valve in the transmission system. This solenoid valve is responsible for regulating the transmission line pressure based on the current flowing through its coil windings.

By adjusting the current flow, the solenoid valve controls the magnetic field and moves its plunger away from the exhaust port.

This action opens the exhaust port, reducing the output fluid pressure regulated by the PC solenoid valve, which in turn decreases the line pressure.

The P0965 fault code specifically indicates an issue with the control circuit range or performance of the Pressure Control Solenoid ‘B’. This means that there is a problem with the electrical circuitry or the functioning of the solenoid valve itself.

It is important to address this fault code promptly as it can affect the proper regulation of line pressure in the transmission system, potentially leading to shifting issues or other transmission problems.

What are the possible causes of the automobile fault code P0965?

If you’re seeing the engine light or service engine soon warning light on your dashboard, it could be due to the fault code P0965. This code is often caused by a faulty pressure control solenoid ‘B’, an open or shorted harness for the pressure control solenoid ‘B’, or a poor electrical connection in the pressure control solenoid ‘B’ circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the issue?

To fix the issue of the Engine Light being ON or the Service Engine Soon Warning Light, start by visually inspecting the wiring harness and connectors. This can help identify the cause, such as a faulty Pressure Control Solenoid ‘B’ or an open or shorted harness. Look for any damaged components and check for broken, bent, pushed out, or corroded pins on the connectors. This step is crucial in troubleshooting and finding a solution.

What should I look for when checking for damaged components or corroded connector pins?

When checking for damaged components or corroded connector pins, there are a few key things to look out for. Start by visually inspecting the related wiring harness and connectors. Check for any signs of damage, such as broken or bent components. Additionally, pay close attention to the connector pins – make sure they are not pushed out or corroded. These issues can often be the cause of a faulty pressure control solenoid or poor electrical connection. So, it’s important to thoroughly examine these areas to ensure everything is in proper working order.
