P2818 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2818 can be elucidated as Pressure Control Solenoid "H" Stuck On. 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. This code is a generic trouble code, meaning it applies to all vehicles equipped with the OBD-II system, especially those made from 1996 up to present. It’s also more common among Audi, Citroen, Chevrolet, Ford, Hyundai, Nissan, Peugeot, and Volkswagen vehicles. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model, powertrain configuration type, to another.

Want to learn something more about the P2818 fault code? 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 P2818 fault code.

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

• There can be distorted pressure control solenoid
• Mucky or contaminated fluid
• Grimy or clogged transmission filter
• Unusable transmission pump
• The transmission valve body might not be functioning properly
• Constricted hydraulic passages
• Erode or damaged connector
• There can be inoperative wiring
• Malfunctioning PCM

1. Engine Control Module - Want to know the most common reason behind the failure in the engine control module? Corrosion or damage because of moisture can cause ECM failure. Corrosion might enter the ECM through the wiring harness and moisture can enter by a failure in the seals in the ECM itself.
2. Automatic Transmission Module - If the transmission module is faulty, then the vehicle might experience erratic gear shifts and throttle response. The engine might also stall will be accelerating and slowing down. Thus, replace faulty automatic transmission module, if required.
3. Powertrain Control Module - The PCM makes the engine and transmission work in tandem. Any issue with the powertrain control module will cause major problems with the efficient running of the vehicle.
4. Transmission Fluid Pump - A failed transmission fluid pump can cause the fluid not being able to circulate in the transmission and the driver may smell the fuel burning. Thus, it might need immediate replacement.
5. Car Battery & Cables - Most of the time the battery cables and connectors are at fault for a particular component not functioning properly. Thus, the battery cable and connector should be checked for and replace in time.
6. Electronic Control Unit - If your vehicle fails to start for no apparent reason, this is also a good indicator that there can be some issues with the ECU. If you check the car battery, starter and other common electrical components, and the vehicle still does not start, a quirky electronic control unit should be the next logical thing to consider.
7. Transmission Fluid Pump Harness - Damaged pump harness can lead to problematic transmission performance and can cause transmission slipping, rough shifts, fuel leakages and delayed engagements. Buy new fluid pump harness now!
8. Diagnostic Tool - In order to fix these errors, you need a few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come in handy to do so and resolve all your vehicle problems. Visit today!

Common Symptoms

• The service engine soon light can start lighting up
• Vehicle might enter limp mode
• Transmission might slip when shifting
• Transmission might start overheating
• Transmission catches in gear
• Decreasing fuel economy
• Some possible misfire-like symptoms

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:

• You must fix the defective PCM
• Make sure to clean the corrosion from connectors
• It is essential to restore the flawed transmission valve body
• Repair or replace the quirky change the fluid and filter

Have a look at our superior variety of transmission control module, powertrain control module, transmission filter, transmission valve body, pressure control solenoid, transmission pump, auto transmission filter, pcm module, ecm module and many more. Now all your problems would vanish within no time.

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

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 inspections related to fluid & wiring

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.

Here are some 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.

Have a look at some 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 P2818 Code

• There can be some faults in the transmission control module
• Negligence in the transmission pressure control solenoid
• Transmission fluid level might be low
• Wiring problems
