What does P0964 Mean? The Pressure Control (PC) Solenoid Valve an electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As current flow is increased, the magnetic field produced by the coil moves the solenoid’s plunger further away from the exhaust port. Opening the exhaust port decreases the output fluid pressure regulated by the PC solenoid valve, which ultimately decreases line pressure. The line pressure solenoid valve regulates the oil pump discharge pressure to suit the driving condition in response to a signal sent from the Transmission Control Module (TCM). engine code P0964P0964 fixobd P0964dtc P0964obd code P0964obd2 P0964P0964 car codediagnostic code P0964car code P0964check engine code P0964fehlercode P0964P0964 fiatcodigo P0964codigo falla P0964P0964 kody b??dówcodigo de falla P0964 What are the common causes of P0964 ? In the majority of cases, a faulty cooling fan motor or relay is to blame for a P0694 trouble code. However, the code may also be the result of electrical issues, including corroded or faulty electrical connectors and shorted wiring. It is also possible that the engine coolant temperature sensor itself is faulty, and may be reporting false information to the PCM as a result. How do you troubleshoot P0964 ? The valves of each cylinder are kept closed using a pair of arms that replace the conventional engine's roller-type rocker arm. P0964 code one of these arms follows the cam profile while the second arm connects to the valves. During normal engine operation the two arms are joined by a locking pin.
