P2822 Pressure Control Solenoid “J” Electrical
OBD-II Trouble Code Technical Description
Pressure Control Solenoid J Electrical
What does that mean?
This is a generic transmission diagnostic trouble code (DTC) and typically applies to OBD-II vehicles equipped with an automatic transmission.
That may include but is not limited to vehicles from BMW, Toyota, Lexus, Nissan, Mitsubishi, Chevrolet, GMC, Mercedes-Benz, etc. Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration.
When the P2822 OBD-II trouble code is set, the Powertrain Control Module (PCM) has detected a problem with the Transmission Pressure Control Solenoid "J". Most automatic transmissions incorporate at least three solenoids that are solenoid A, B and C. However, for this DTC, the transmission contains even more. The trouble codes related to the "J" solenoid are codes P281F, P2820, P2821, P2822, and P2823. The code set is based on the specific malfunction that alerts the PCM and illuminates the Check Engine Light.
The purpose of the Transmission Pressure Control Solenoids is to control the pressure of the fluid for the proper operation of an automatic transmission. The PCM receives an electronic signal based on the pressure within the solenoids. An automatic transmission is controlled by bands and clutches that change gears by having fluid pressure in the right place at the right time. Based on the signals from associated devices monitoring the speed of the vehicle, the PCM controls the pressure solenoids to direct fluid at the appropriate pressure to various hydraulic circuits that change the transmission gear ratio at the correct time.
The code P2822 is set by the PCM when the Pressure Control Solenoid "J" is experiencing an electrical malfunction.

What are some P2822 troubleshooting steps?
Prior to beginning the troubleshooting process for any malfunction you should research the Technical Service Bulletins (TSB’s) for the specific vehicle by year, model and transmission. In some circumstances this can save a lot of time in the long run by pointing you in the right direction. You should also check the vehicle records to verify the last time that the filter and fluid was changed if possible.
Fluid & Wiring Inspections
The first step is to check the fluid level and examine the condition of the fluid for contamination. Prior to changing the fluid, you should check the vehicle records to verify the last time that the filter and fluid was changed.
A detailed visual inspection to check the condition of the wiring for obvious defects is next. Check the connectors and connections for security, corrosion and damaged pins. This should include all wiring and connectors to the transmission pressure control solenoids, the transmission pump and the PCM. Depending on the configuration, the transmission pump may be electrically driven or mechanical driven.
Advanced Steps
The advanced steps always become very vehicle specific and require the appropriate advanced equipment to perform accurately. These procedures require a digital multi meter and the specific technical references for the vehicle. You should obtain the specific troubleshooting guidelines for your vehicle prior to proceeding with the advanced steps. Voltage requirements may very based on the specific model of the vehicle. Fluid pressure requirements will also vary based on the transmission design and configuration.
Continuity Checks
Unless otherwise specified by the technical data, the normal readings for wiring and connections should be 0 ohms of resistance. Continuity checks should always be performed with the power removed from the circuit to avoid shorting the circuit and creating more damage. Resistance or no continuity is an indication of faulty wiring that is open or shorted and must be repaired or replaced.

"Delete Error Code Permanently, Disable DTC Error Code Function for p2822 in the ECU"
In extreme cases, we even have the option to permanently remove the specific DTC p2822 and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.
Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of p2822.
