<<See All OBD Codes

OBD error code P229B troubling you? Can’t understand what it means and how it relates to your vehicle’s fall in engine performance? Well, error code P229B is concerned with fuel pressure regulator 2 pressure too high issue. It is a generic error code and applies to all OBD-II vehicles. To know more about this error code, have a look at the sections below.

OBD error code P229B indicates problems with the fuel delivery system. The PCM, also known as the powertrain control module is responsible for monitoring the fuel pressure. This issue of error code P229B can be caused by a leaking injector, causing the PCM to set OBD error code P229B after detecting exceeding control limits from the fuel pressure regulator.

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

• Bad fuel pressure regulator
• Non-operative fuel pump
• Malfunctioning fuel pressure sensor
• Fuel injector being damaged or leaking
• Problems with the powertrain control module

1. Fuel Pressure Regulator - You really can’t have a healthy EFI system if your fuel pressure regulator is not in good shape, and we are sure that is something that you really don’t want to face as it can also lead to problems like OBD error code P229B. Don’t take chances and replace the faulty ones today.
2. Fuel Pump - Did you know that the fuel pump is responsible for delivering fuel from the gas tank to the engine at the appropriate pressure required for performance demands and if that goes wrong you can have a serious vehicle breakdown. Don’t let that happen to your vehicle and replace the bad one today with brand new Delphi fuel pumps or Holley fuel pumps or any such top brand fuel pumps from us.
3. Fuel Pressure Sensor - Remember that if the sensor the faulty, it will not read the air pressure correctly thus affecting the air to fuel ratio. Buy new pressure sensor from us to avoid such issues.
4. Fuel Injector - If your vehicle’s fuel injector is corroded it will not only lead to problems while driving, but the effects will continue even as the engine runs low on energy. To avoid all these issues, it is advisable to replace the faulty fuel injector with a new one. This might help you to get rid of this error code P229B.
5. Powertrain Control Module - A faulty powertrain control module can be very detrimental for your vehicle’s health. It can create issues such as stalling while running or failing to start condition. If you need to get rid of these issues you can replace your bad PCM with a new one today with us.

Interested in knowing the symptoms to obd code P229B? 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 Control Limits - Pressure Too High.

Common Symptoms

• Steep fall in engine efficiency
• Stalling engine
• Rise in fuel consumption

Have a look at some ways with which you can correct the P229B code:

• Start by repairing or replacing the faulty fuel pump
• Next, undergo fixing or replacement for the leaking fuel injector
• Replacement of the faulty fuel pressure regulator is also important
• Also, make sure that powertrain control module and fuel pressure sensor are working well, otherwise undergo their replacement too

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 P229B 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 P229B. 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. Also 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 P229B 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
