Error Code P2815: What It Means & What To Do?

<<See All OBD Codes

The trouble code P2815 can be described as Pressure Control Solenoid "G" Control Circuit High. It is the shift solenoid valve ‘F’ which is turned ON or OFF by the transmission control module in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and engine control module. After that the gears would be shifted to the optimum position.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code. The P2815 trouble code would indicate that a Shift Solenoid F which is not as per the predetermined limit has been detected by the ECM. Now when this would occur, the fault code would be stored and there would be an illumination of the malfunction indicator light.

What causes this problem with the Pressure Control Solenoid "G" Control Circuit High?

• Too little fluid level
• Stained or contaminated fluid
• Dirty or clogged transmission filter
• There can be inoperative transmission valve body
• Constricted hydraulic passages
• There can be distorted transmission
• The pressure control solenoid might be flawed
• Corroded or damaged connector
• Malfunctioning wiring
• Unusable PCM

1. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
2. Transmission Fluid Pump - The first indication of any transmission related problem will the illumination Check Engine Light. Other major symptoms indicating bad transmission fluid pump can be bad shifts, delayed response and fuel burning smell coming from under the hood. Thus, immediate replacement is advisable.
3. Transmission Fluid Pump Harness - Damaged transmission fluid pump harness can cause problematic transmission performance and can lead to transmission slipping, rough shifts, fuel leakages and delayed engagements. Buy new harness now!
4. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
5. Automatic Transmission Module - A defective transmission module will affect the gear shift mechanism and also affected during acceleration and deceleration. This will lead to affected engine performance and fuel delivery system. Thus, replace faulty transmission module now!
6. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.

Here are some steps which you should follow in order to diagnose this fault code:

• Inspect for technical service bulletins which pertain to the vehicle, symptoms, and codes. In some circumstances this can save a lot of time in the long run by pointing you in the right direction. You can always check the vehicle records to verify the last time that the filter and fluid was changed if possible.
• Initial step is to make sure the fluid level is correct and inspect the condition of the fluid for contamination. After that perform visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots should be performed.
• Next is to check the connectors and connections for security, corrosion and damaged pins. This process must include all wiring and connectors to the transmission solenoids, transmission pump and the PCM. It depends upon the configuration; the transmission linkage should be inspected for security and binding issues.
• The advanced steps become very vehicle specific and require the appropriate advanced equipment to perform accurately. These procedures require a digital multimeter and the specific technical references for the vehicle. Voltage requirements will vary based on the specific year and model of the vehicle. You should follow the specific troubleshooting chart for your vehicle.
• Continuity checks should always be performed with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance unless otherwise specified by the technical data. Resistance or no continuity is an indication of faulty wiring that is open or shorted and must be repaired or replaced.

Common Mistakes When Diagnosing The P2815 Code

• Low transmission fluid level
• Quirks in the transmission pressure control solenoid
• Transmission control module might start failing
• Wiring related issues
