What is P0796 fault code? What is the Pressure Control Solenoid Performance / Stuck Closed description? How can I fix the P0796 fault? What are the symptoms, causes, and solutions for the P0796 fault code?
What is the P0796 Fault code? What does it signify?
When the powertrain control module, or PCM, receives an abnormal voltage from the circuit’s electronic pressure control solenoid/circuit, a code P0796 will be set.
The electronic pressure control solenoid, which is used to monitor and facilitate transmission gear changes, is one of the parts. The PCM regulates transmission oil pressure by using information from circuit “C”. Incorrect gear changes will be caused if the transmission oil pressure is not as high as expected. In this instance, the fault code P0796 will be applied.
Most automatic transmissions include at least three solenoids. These solenoids are A, B, or C.
Transmission pressure control solenoids are responsible for controlling the fluid pressure to ensure that the automatic transmission works properly. The solenoids convert the fluid pressure into an electronic signal that is sent to the PCM. The fluid pressure is at the correct place at the right moment to allow for gear changes to be controlled by belts or clutches. Based on vehicle speed data, the PCM controls the pressure control solenoids. It then directs fluid pressure through various hydraulic circuits in order to shift the vehicle into the desired gear. If the “C” pressure solenoid fails to work properly or is stuck in an off position, a P0796 code will be triggered.
The P0796 fault code can affect vehicles of various makes and models, including Ford, Mercury, Lincoln Jaguar, Chevrolet Toyota, Nissan, Allison/Duramax Dodge Jeep Honda Acura, Acura, Acura, Acura, Acura, Acura, Toyota and Audi.
Note: Do not confuse pressure control solenoids with shift solenoids. They are both used for different purposes.
What causes the P0796 Fault code?
Here are some reasons why P0796 should be set.
- – Defective electronic pressure control solenoid “C”
- – Blockage of transmission fluid passage lines
- – Low or dirty transmission oil
- – Very dirty and clogged transmission filters
- – Broken cables, loose or corroded connectors
- – Electric components that cause open circuit or short circuit
- – Defective transmission pump
- – A defective hydraulic control unit (also known by valve body or transmission system)
- – Gearbox mechanical failures
- – Faulty transmission control module or PCM (rarely).
What are the P0796 Malfunction Code Symptoms
You may experience the following symptoms if your vehicle has the code P0796:
- – Illumination at the check engine lights
- – The transmission warning light is on
- – Incorrect gear changes
- – Difficulty with gear changes
- Transmission may be stuck in a particular gear
- – Torque converter clutch may not engage or disengage
- – Gear shifting during gear shifts
- – The gearbox is overheated
- – Increased fuel consumption
- – Misfire-like symptoms
- PCM can reduce vehicle acceleration and enter safe mode
How do I fix the P0796 fault code?
The following repairs may be able to resolve the P0796 fault code:
- – Replacing the “C” electronic pressure control solenoid
- Cleaning blocked transmission fluid passage lines
- – Replacing dirty transmission oils and filters
- – Filling in the gaps with transmission oil
- – Repair of short circuit-producing electrical components
- – Replacing damaged cables or connectors
- – Repair of or replacement of the transmission pump
- – Replacing a defective hydraulic control unit (valve head / transmission computer).
- – Repair of internal mechanical faults in transmissions
How serious is the P0796 Fault code?
This code is crucial to the operation the shift function. You should fix it as soon as you can. Code P0796 cannot be fixed immediately. If you drive this way, it may lead to further malfunctions.
