Guide To P2719 OBD Error Code Solutions

If you feel a sudden drop in the engine performance and continuous stalling and hard idles along with flashing of check engine lights on the dashboard, this may be an indication of OBD Code P2719 being stored in the PCM/ECM. OBD code P2719 means Pressure Control Solenoid D Control Circuit Range/Performance Issue.

On most shift solenoids, the passage is normally open; that is, when you energize the solenoid, the shaft closes the hydraulic circuit, which shuts off the flow of oil. Pressure control solenoids work exactly the opposite way: They’re normally closed, and open when energized. This is so that, if the system fails, pressures go high automatically. If they worked the other way, a simple blown fuse would allow pressures to drop, and could cause catastrophic transmission damage. Other than that, pressure control solenoids are identical to any other transmission solenoid, especially on the operational front.

OBD code P2719 gets stored in the PCM if the pressure control solenoid “D” is not performing accurately.

What causes this problem with the Pressure Control Solenoid "D" Control Circuit Range/Performance?

• Pressure control solenoid “D” failure
• Pressure control solenoid wiring and harness damaged or broken
• Loose connections to the solenoid circuit
• Low transmission fluid levels
• Transmission fluid pump leakage
• Transmission torque converter problematic
• TCM error

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. Engine Wiring Harness - Your car ECM would not operate properly if there are some cracks or break in the engine wiring harness. Corrosion as well as physical damage are the most common reasons why you should replace an engine wiring harness. Purchase high grade engine wiring harness online from Parts Avatar Canada.
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. 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.
5. 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.
6. 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!
7. Automatic Transmission Solenoid – If you are experiencing roughness during shifting of gears, it is most likely because of too much fluid pressure in the hydraulics or because of a malfunctioning transmission solenoid.
8. Automatic Transmission Sensor – If the signals are lost from the transmission speed sensors, the PCM will set a DTC and illuminate the Check Engine Light on the vehicle dashboard. It also can indicate that there is an increase in tailpipe emissions is occurring that surpasses acceptable limits for environmental contaminants from motor vehicles. Thus, replace it immediately.
9. Auto Transmission Torque Converter – A bad torque converter will take the transmission longer to engage the engine, resulting in higher than normal stall speeds. Thus, replace the faulty component now!
10. Transmission Fluid – Low transmission fluid symptoms also include the slipping of the engaged gear. It does not let the gear to stay in the mode you have selected. If the fluid level is right, the culprit must be the residue build up that impedes the fluid to flow freely.

Interested in knowing the symptoms to obd code P2719? If yes, then you have arrived at the right place. We at PartsAvatar have listed out few common symptoms associated with this fuel injector problem.

Common Symptoms

You can easily find all these parts with us. Not only that you can get these parts shipped to your door free, if your cart value happens to exceed $99.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2719 code to be stored:

• Install a scan tool in vehicles OBD-II port to check if P2719 is present or not.
• Freeze frame data and test drive to check if the code reappears under same conditions.
• If the Check Engine Light returns upon test, then the code is confirmed.
• Search technical service bulletins (TSB) in your vehicle information source. If you find one that matches the symptoms and code/s presented by the vehicle in question, it will very likely aid you in your diagnosis. TSB listings are compiled from thousands of successful repairs.
• Check the transmission fluid for low levels and contamination and replace it immediately.
• Perform a visual inspection of wiring and connectors for any damage, breaks, or shorted wiring.
• If the wiring is okay, the solenoid itself will be tested to confirm operation. Perform a continuity test to check for and open or short in the solenoid circuit and wiring.
• Check for the voltage of pressure solenoid control circuit “D” and make sure it is not excessively low. If low voltage is confirmed, transmission pressure solenoid is faulty.
• A diagnostic of the ECU (Engine Control Unit) will be performed, if the voltage is not low and sensors are fine.

Common mistakes when diagnosing the P2719 code

P2719 is an uncommon code and following all diagnostic steps is important so nothing is overlooked. Transmission pressure solenoid should be properly examined and replaced if faulty. Always confirm low voltage for solenoids before any replacement is performed and avoid going to the ECU straightaway.
