Error Code P2811: What It Means & What To Do?

<<See All OBD Codes

The trouble code P2811 can be explained as Pressure Control Solenoid "G" Intermittent. The pressure control solenoids are used by the transmission control module (TCM) to control the hydraulic pressure in the transmission which is required to apply the various clutch packs in the transmission that provide the different gear ratios required to efficiently propel the vehicle down the roadways.

If the transmission control module would detect a variation in the voltage coming from the pressure control solenoid "G" circuit that is outside the parameters set by the automobile manufacturer, then it would store the P2811 error code. This would also give rise to the illumination of the check engine light.

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

• Polluted fluid
• The transmission filter might be grubby or clogged
• Inadequate fluid level
• Unsound PCM
• Faults in the transmission valve body
• The shift solenoid might not be working properly
• Corroded or shivered connector
• Some defects in the wiring
• Cramped hydraulic passages
• There can be an internal failure in the transmission

1. Engine Control Module - It is not always the components, but the ECM that can also be faulty. It can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
2. Transmission Fluid Pump - Faulty transmission fluid pump can cause harsh shifts and audible transmission noise. This leads to decreased performance and chances of increased physical damages to the transmission components. Thus, replace it immediately.
3. Powertrain Control Module - Powertrain Control Module can also be faulty in rare cases and thus needs through checks for system and software errors. Thus, check and replace it, if required.
4. Car Battery - Faulty car battery can have the problem of overheating and fast discharging. Thus, it can affect the motor performance as well as damaged major components. Replace it immediately.
5. Electronic Control Unit - The ECU manages the cooling system to control the battery operating temperatures and thus must be replaced if found faulty. Thus, buy new ECU modules and components from us!

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2811 code to be stored:

First of all, you should research the Technical Service Bulletins (TSBs) for the specific vehicle by year, model and transmission before you start with the troubleshooting process for any malfunction.

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.

The fluid level should be 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.

Then inspect 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.

The checks for continuity 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. Make sure that you get it repaired or replaced as per the requirements.

Common Mistakes When Diagnosing The P2811 Code

• Malfunctioning transmission pressure control solenoid
• Wiring related issues
• There can be a failure in the transmission control module
• Diminishing transmission fluid level
