It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2147 code to be stored:

Start with connecting the vehicle OBD scanner to the diagnostic port and retrieving all the codes stores and freeze frame the data. All the codes set before the P2147 will have to be checked and resolved first. Once this is done the car should be taking on a test drive and see if the code resets. If it doesn’t then it was most likely an issue with the previous codes, if it sets you can continue your diagnostics.

Carry out a thorough visual inspection of the wiring and circuitry. All the electrical components should be observed for any signs of damage like corrosion of pins, broken or shorted circuits, burned or broken wires etc. All these issues will have to be resolved and then the codes should be cleared. Another test drive is run to see if the code returns, if it doesn’t then the issue was with the electrical components and has been successfully resolved. If the code does return then the next step is to monitor the injector operation using the scan tool. For doing this a multimeter will have to be used to check the voltage at the fuel injector groups and also the fuel injectors separately. All readings found should be as per the manufacturer's requirements, if they’re not then necessary repairs will have to be made or replacements. If all this isn’t helping resolve the code, then the ECU will be tested to check for any malfunction and accordingly be repaired or replaced. In case of ECU replacement, some reprogramming will be needed, for this it is very important that an experienced professional is approached.

Common Mistakes When Diagnosing the P2147 Code

• Not following the diagnostic steps in order
• Replacing the ECU overlooking the issues with the wiring and other electrical components
