P2814 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2814 can be explained as Pressure Control Solenoid "G" Control Circuit Low. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

If the engine control module would detect a variation in the voltage coming from the shift solenoid F that is outside the parameters set by the automobile manufacturer, then it would store the P2814 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" Control Circuit Low?

• The fluid level might not be enough
• Unwashed or contaminated fluid
• Soiled or clogged transmission filter
• Unusable transmission valve body
• Confined hydraulic passages
• Transmission has internal failure
• There can be distorted pressure control solenoid
• Corroded or damaged connector
• Broken wiring
• The PCM might not be functioning properly

1. Transmission Fluid Pump Harness - The fluid pump harness can also be faulty causing transmission to underperform due to transmission slipping and harsh shift. Thus, check for harness faults and replace it now!
2. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have the best auto parts for our customers.
3. Automatic Transmission Module - Faulty transmission module can cause problematic down shifts and upshifts, leading to stalling while accelerating or slowing down. This can also hamper many transmission system parts. Thus, replace it now!
4. 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.
5. Automatic Transmission Filter - A faulty Automatic Transmission Filter can be troublesome. You can always rely on us as we have the best auto parts for our customers.
6. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
7. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2814 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.

Fluid & Wiring Inspections

The first 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.

Advanced Steps

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

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 P2814 Code

• Transmission control module might start failing
• Low transmission fluid level
• Some issues related to the wiring
• Faults in the transmission pressure control solenoid
