<<See All OBD Codes

Is your engine stalling or are you struggling with lowered fuel efficiency? Is your vehicle eating up too much fuel? If your answer to any of these questions is “YES” then there are chances that your car has developed the obd error code P2157. Wondering what is an obd error code P2157 indicates? Well, OBD Code P2157 is a generic OBD-II code that Indicates that your fuel injector group D circuit is high.

Your vehicle’s ECM is responsible for monitoring the fuel injectors learning values and if it notices that they are beyond normal operating parameters, it sets P216C. Most of the time, this code is set when the car’s engine control module detects that one or both of the fuel injectors in that group are not functioning properly. To know more about its few common causes, take a look at the section below.

What causes this problem with the Fuel Injector Group D Circuit High?

• Bad fuel injector or injectors
• Malfunctioning engine control module
• Faulty fuel injector wiring harness
• Internal issues with the fuel injector wiring
• Problems with the fuel injector connector

1. Engine Control Module - Engine control module of your vehicle is your vehicle’s engine computer. If it happens to be damaged or corroded then it can lead to creating a short within the ECM, or corrosion can enter the ECM and then move to the wiring harness. This can happen even when being exposed to a wide range of elements when the car is in certain environments. If you are looking for Engine Control Module then have a look at our collection. You will easily find one for your vehicle make & model.
2. Powertrain Control Module - Error code P2157 flashing? Yes? Then you must check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
3. Fuel Injector - Faulty fuel injectors? Facing error code P2157? Are you experiencing rough idles and difficulty in starting. If yes, then you must undergo faulty fuel injectors replacement. Remember that fuel injector can also crack or break leading to leakages and should be replaced immediately
4. Fuel Injection Harness - We have in stock high end fuel injection harness and all related parts for every make and model on the Canadian road. All you need to do to get them is to browse through our website and order your needed parts.
5. Fuel Injection Connector - When OBD code P2157 flashes on your instrument panel, chances are that there is a problem not only with your fuel injector circuit but also with the connectors. Replace the damaged connectors with brand new ones only at Parts Avatar Canada.
6. Ohmmeter - In order to be that DIY guy, you need to few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come handy to do so, So why not have a look?

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• 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 injector system we would recommend you to get rid of them first before attempting to solve the error code P2157.
• 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 constant power supply to the Fuel Injector Group D using ohmmeter. Next, make sure you check all the fuel injection system fuses and relays for any damage. Also conduct a continuity and resistance test for circuits related to Fuel Injector Group D. Lastly remove fuel Injector and observe fuel spray pattern for abnormalities.

Common Mistakes When Diagnosing the P2157 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.

• Bad fuel injector
• Failing car’s PCM
• Issues with the wiring
