Code P0795 2006 Nissan Altima Sedan Description

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.

Code 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.
