What Does Code P0965 Mean?
If your vehicle has exhibited an illuminated malfunction indicator lamp (MIL), and has stored a code P0965, it means that the powertrain control module (PCM) has detected a problem with a specific electronic pressure control solenoid (EPCS) or solenoid circuit for the automatic transmission. The designation B usually refers to a secondary EPCS/circuit. This code is used exclusively in vehicles equipped with automatic transmissions. Automatic transmissions in OBD-II vehicles are controlled electronically by the PCM or a stand-alone controller, called a transmission control module (TCM). Most transmission controllers are integrated into the PCM. The major components of the transmission control system are:- Control module
- Controller area network (CAN)
- Numerous sensors and solenoids
- A powerful hydraulic pump
- One or more electronic pressure control solenoid/s
- An assortment of shift solenoids
- A torque converter clutch solenoid
- A hydraulic valve body


What are the common causes of code P0965 ?
- Transmission (front) pump failure
- Open or shorted wiring or connectors in the EPCS circuit
- Defective electronic pressure control solenoid
- Low or subpar transmission fluid
What are the symptoms of code P0965 ?
- Delayed transmission engagement
- Erratic transmission shifting
- The transmission may fail to shift
- Harsh transmission shifting
- A loud whining noise from the transmission torque converter/bell housing area
How do you troubleshoot code P0965 ?
To accurately diagnose a code P0965, you will need a diagnostic scanner (scan tool), a digital volt/ohmmeter (DVOM), a transmission pressure gauge, and vehicle factory digrams and information (All Data DIY). I like to begin my diagnosis with a visual inspection of transmission control wiring and connectors. Remember that a large segment of the transmission control harness is inside the transmission hosing.

Hi, I have a nissan sentra 2016.and I ran over a pumper on the fwy at carpool line. And highway patrol told me to drive it out to the nearest exit. I was on 91fwy. About to pass 605 fwy .so I was on carpool line and had to drive to the right hand side to go in to the 605 get and drive to the nearest exit that was a long drive like maybe like a 5 minute drive to the nearest gastation. That when the highway patrol rocked my car for about 4 hours.till they broke the pumper in to one little peace .I have pictures. then like about a couple of day my car didnt want to drive from the brakes it broke then it was the alignment and was holding after then once it gets hot it doesn’t want to drive but the insurance wants me to pay for it too bring it down and open it and see what’s going on with it if it’s related to the accident so they can reimburse me.
I want to see if these codes are related to this accident so the insurance could pay my car
Hi Laura,
Since the code was never an issue before the incident, it must have been caused by damage from the incident. You can likely find a shop to work with you on collecting payment from the insurance company. Get on the phone and be charming. Best wishes.
