P282F Pressure Control Solenoid “K” Control Circuit Low
OBD-II Trouble Code Technical Description
Pressure Control Solenoid K Control Circuit Low
What does that mean?
This is a generic transmission diagnostic trouble code (DTC) and applies to OBD-II vehicles with an automatic transmission. That may include but is not limited to vehicles from Ford, GMC, Chevrolet, Honda, BMW, Saturn, Land Rover, Acura, Nissan, Saturn, etc. Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration.
In most circumstances automatic transmissions will incorporate at least three pressure control solenoids know as solenoid A, B and C. Newer transmissions tend to have more gears and more solenoids, giving you solenoids D, E, F, etc. Various trouble codes are associated to the "K" solenoid control circuit and some of the most common include P282D, P282E, P282F, and P2830. When the P282F OBD-II trouble code is set, the Powertrain Control Module (PCM) has detected a problem with the transmission pressure control solenoid "K" control circuit. The specific code set is based on the specific malfunction that is detected by the PCM.
An automatic transmission is controlled by bands and clutches that change gears by having fluid pressure in the right place at the right time. The purpose of the transmission pressure control solenoids is to adjust the pressure of the fluid for the automatic transmission to operate properly and shift smoothly. The PCM monitors the pressure within the solenoids and directs fluid to various hydraulic circuits that change the transmission gear ratio precisely as needed.
Code P282F is set by the PCM when it detects that the pressure control solenoid "K" control circuit is experiencing a low voltage condition and therefore is not functioning properly.

What is the severity of this DTC?
The severity of this code normally begins as moderate, but it can progress to a more severe level rapidly when not corrected in a timely manner. In circumstances that result in the transmission banging into gear permanent internal damage can be caused making the problem a severe issue.
What are some of the symptoms of the code?
Symptoms of a P282F trouble code may include:

What are some P282F 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 situations this can save a lot of time in the long run by pointing you in the right direction.
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 (if possible) 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. Based on the specific configuration, the transmission pump may be driven electrically or mechanically.
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 always obtain the specific troubleshooting data for your vehicle prior to proceeding with the advanced steps. Voltage requirements will vary based on the specific model of the vehicle. Fluid pressure requirements may 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 p282f in the ECU"
In extreme cases, we even have the option to permanently remove the specific DTC p282f 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 p282f.
