P0797 2005 NISSAN ALTIMA SEDAN - Pressure Control Solenoid 'C' Stuck On
P0797 2005 NISSAN ALTIMA SEDAN Possible Causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty pressure control solenoid valve 'C'
- Pressure control solenoid valve 'C' harness is open or shorted
- Pressure control solenoid valve 'C' circuit poor electrical connection
First diagnose P0797 2005 NISSAN ALTIMA SEDAN code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
P0797 2005 NISSAN ALTIMA SEDAN Tech NotesWhen a transmission solenoid is malfunctioned, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure and that the transmission will need to be rebuilt or replaced.
Cost of diagnosing the P0797 2005 NISSAN ALTIMA SEDAN code
Labor: 1.0The cost of diagnosing the P0797 2005 NISSAN ALTIMA SEDAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P0797 2005 NISSAN ALTIMA SEDAN code detected?The gear required by the ECM does not match the actual gear when driving
P0797 2005 NISSAN ALTIMA SEDAN Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Shift shock
P0797 2005 NISSAN ALTIMA SEDAN MeaningThe 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).
