P0960 is a diagnostic trouble code (DTC) for "Pressure Control Solenoid A Control Circuit/Open". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
The P0960 code is a generic powertrain code related to the transmission, including pressure faults and sensor failures. In this case, the engine control module (ECM) has received a signal noting that the pressure control solenoid for the A control circuit is open.
Electronically controlled valves shift and maintain the correct gears needed for optimal performance. The valve body contains both the shift solenoid valves and pressure control solenoid valves. The shift solenoid valves control the activation (or deactivation) of such items as the clutch, brakes, and engaging/disengaging the gears.
A vehicle will use one or more pressure control solenoid valves to control the hydraulic pressure in a vehicle’s automatic transmission. Hydraulic pressure is generated at the pump, which is driven by the engine through the torque converter housing.
A code P0960 will be stored when the transmission control module sees a fault with one of the valves, including a voltage signal stating that the A control circuit is remaining open, or not receiving the reference voltage needed to operate. .
Several problems may cause a P0960 code including:
Symptoms of a P0960 code may include:
A mechanic may use several methods to diagnose a P0960 trouble code, including:
At times, the pressure control solenoid or transmission control module may be replaced when the fault lies in a defective harness or poor electrical connection. It is recommended to thoroughly diagnose a P0960 trouble code for all possible causes before replacing more expensive components.
Because a vehicle’s safe driving operation most likely will be impacted due to faults that store a P0960 code, this code is considered a potentially serious code. When this code appears, it is recommended to immediately take your vehicle to your local service center or mechanic for repair and diagnosis.
Several repairs can fix a P0960 trouble code and include:
As with any transmission-related trouble code, be sure to check the transmission fluid level and quality prior to any repairs.
