Error Code P2819: What It Means & What To Do?

<<See All OBD Codes

The trouble code P2819 can be explicated as Pressure Control Solenoid "H" Electrical. The pressure control solenoid is 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 various gear ratios which are required to efficiently propel the automobile down the roadways. Now when the transmission control module would detect a pressure control solenoid which is not performing as per the requirement, then it would set up the P2819 error code. This would give rise to the flashing up of the check engine light.

Do you want to gain some more knowledge about the P2819 trouble code? The vehicle speed signal is utilized by the transmission control module (TCM) to decide the real gear position (1st, 2nd, 3rd, 4th. 5th or 6th gear). Then the transmission control module would compare the actual gear with the shift schedule in the TCM memory to detect shift solenoid valves and valve body mechanical issues. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Pressure Control Solenoid "H" Electrical?

• There can be distorted pressure control solenoid
• Stained or contaminated fluid
• Grimy or clogged transmission filter
• Imperfect transmission pump
• Broken transmission valve body
• Confined hydraulic passages
• Abrade or damaged connector
• The wiring might be flawed
• Quirks in the PCM

1. Electronic Control Unit - ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
2. Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
3. 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.
4. Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
5. Car Battery & Cables - Most of the time it is the cables and connectors that are at fault and are a cheap and easy way to diagnose this error. Thus, replace faulty wiring and connectors immediately.
6. Diagnostic Tool - In order to be that DIY guy, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come in handy to do so, so why not have a look?

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2819 here:

Common Symptoms

• Check engine light might come into signal
• Vehicle entering limp mode
• Transmission might start slipping when shifting
• Excessive heat in the transmission
• Transmission catches in gear
• Fall in fuel economy
• Misfire-like symptoms may exist

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• It is essential to clean the corrosion from connectors
• Repair or replace the quirky wiring
• Rehabilitate the defaults in the pressure control solenoid
• The malfunctioning transmission pump should be repaired or replaced as per the need
• Carefully adjust the faults in the change the fluid and filter
• The transmission valve body should be restored to working order
• It is necessary to perform proper service of the unsound PCM/ECM

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

• Check for technical service bulletins which pertain to the vehicle, symptoms, and codes prior to beginning 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. Here are some steps:
• 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.
• 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 P2819 Code

• Flaws in the transmission control module
• There can be some issues in the transmission pressure control solenoid
• There might be less transmission fluid level
• Failure in the car wiring
