P0795 2005 NISSAN ALTIMA SEDAN - Pressure Control Solenoid Valve 'C'
P0795 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
P0795 2005 Nissan Altima Sedan Tech Notes
When 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.
When is the code detected?
The P0795 code is detected when the when normal voltage is not applied to solenoid due to open or short or when TCM detects as irregular by comparing target value with monitor value.
P0795 2005 Nissan Altima Sedan Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Shift shock
P0795 2005 Nissan Altima Sedan Meaning
The pressure control solenoid valve 'C' is normally low pressure control solenoid. The solenoid is activated to control the apply and release of the 2nd brake and 1st and reverse brake, and torque converter clutch. Lock-up operation, however, is prohibited when A/T fluid temperature is too low. When the accelerator pedal is depressed (less than 1/8) in lockup condition, the engine speed should not change abruptly. If there is a big jump in engine speed, there is no lock-up.
