<<See All OBD Codes

OBD error code P229D is a generic powertrain diagnostic trouble code, commonly referred as DTC. It applies to all OBD-II vehicles. In Spite of the fact that it is a generic code but the repair steps may vary depending upon the specific make manufacturer. This code might lead to fall in engine efficiency and a rise in fuel consumption. If you wish to know more about this error code P229D, then you must go through our subsequent sections.

Ever wondered what this P229D code depicts? What is your vehicle trying to convey you? P229D error code is a generic OBD code that indicates that your vehicle’s powertrain control module has detected non performing fuel pressure regulator or in other words it detects fuel pressure regulator 2 exceeding learning limits - too high. To know more about this code and few of it’s common causes, take a look at the following section.

What causes this problem with the Fuel Pressure Regulator 2 Exceeded Learning Limits - Too High?

• Damaged fuel injector that starts leaking
• Defective fuel pressure regulator
• Malfunctioning fuel pump
• Problems with the powertrain control module
• Issues with the fuel pressure regulator wirings

1. Fuel Pressure Regulator - De-acceleration and rough engine running are few of the faulty fuel pressure regulator issues. Do not ignore them and replace the faulty ones with a brand new ones today.
2. Fuel Pump - If your vehicle is facing faults with fuel pump, then now is the time you replace it to avoid engine surging and engine performance issues.
3. Fuel Pressure Sensor - Decrease in power, acceleration and fuel efficiency are another symptom of a potential problem with the vehicle's fuel pressure sensor, so don’t think twice and replace the faulty ones now.
4. Fuel Injector - Is your car suffering from fuel injectors damage? Well, we suggest you not to wait any longer as defective fuel injectors can result in drivability issues especially when the engine is running low on energy. Avoid rough engine functioning and occurence of OBD error code P229D today by replacing the old fuel injectors with a new one today with us.
5. Powertrain Control Module - Also abbreviated as PCM is an integral control unit. So a defective one should be changed immediately replaced to avoid any further damage. If you need one for your car, you can easily find with us for your specific car make and model.

Interested in knowing the symptoms to obd code P229D? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with Fuel Pressure Regulator 2 Exceeded Learning Limits - Too High.

Common Symptoms

• Stalling engine
• Rising vehicle’s fuel consumption

Have a look at some ways with which you can correct the P229D code:

• Repair or replace the faulty fuel pump
• Undergo fuel pressure regulator replacement
• Repair or replace the leaking fuel injector
• Make sure to repair or replace the faulty powertrain control module

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of Fuel Pressure Regulator, Fuel Pump, Fuel Pressure Sensor, Fuel Injector, Powertrain Control Module and many more. Now all your problems would vanish within no time.

In order to diagnose this error code P229D you will need to use a scanner to check for the stored error code.

Next, you will have to connect a scanner to the diagnostic port of the vehicle and recover the codes and freeze frame data. This will help you in further diagnosis. Now you will need to conduct a road test and check what all codes return.

If you come across any other codes related to fuel delivery system we would recommend you to get rid of them first before attempting to solve the error code P229D.

To undergo a complete diagnosis of this error code, you will need few tools such as diagnostic scanner, a digital volt/ohmmeter, and a reliable vehicle information source. While diagnosing make sure that you carefully check the for the pressure to the Fuel pressure regulator 2.

Next, make sure you check all the fuel injection system fuses and relays for any damage. Lastly remove fuel Injector and observe fuel spray pattern for abnormalities.

Common Mistakes When Diagnosing the P229D Code

There are chances that you undergo engine control module replacement, but it might not be needed. This way you will end up spending unnecessary bucks on your car. The code could be solved with a simple computer learn procedure or ecu reprogramming. Therefore a proper diagnosis is always recommended.

• Failing fuel pressure regulator
• Failing fuel pump
• Fuel injector leakage
• Failed powertrain Control Module (PCM)
• Problematic wiring
