Error Code P02F7: What It Means & What To Do?

<<See All OBD Codes

The OBD Code decreased engine performance can be defined as cylinder 10 injector circuit range/performance. There are special transistors known as “drivers” in the engine control module to turn the fuel injectors on and off in the fuel injection system. If the powertrain control module would not be able to control the fuel injector for cylinder number three, then it would start triggering the P02F7 fault code.

This error code would imply that the powertrain control module might have experienced an out of range or some issues related to the problem where fuel injector for the #10 cylinder has been involved. The malfunctioning of the fuel injector can be because of a lot of reasons. That’s the reason why it is essential to diagnose and repair this issue as soon as possible. If there is some fault in the fuel injector, then it would cause ripples down the line, which would mean that the engine’s operating parameters would change due to mixed signals at the powertrain control module.

Make sure that you address this problem to prevent damage to other internal components. A fuel injector which is faulty might affect the spark plug, can cause detonation, oxygen sensor and other components as well. You can always refer to the vehicle specific repair manual so that you can determine the location of the #10 cylinder for the application.

What causes this problem with the Cylinder 10 Injector Circuit Range/Performance?

• Some faults in the fuel injector 10
• The fuel injector 10 can be dirty
• The fuel injector 10 can be plugged
• The harness of fuel injector 10 might be opened or shorted
• Bad electrical connection in the fuel injector 10
• The engine control module might be malfunctioning

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P02F7 here:

Common Symptoms

• Illumination in the service engine soon warning light
• Decrease in the overall engine performance
• There can be an increase in the fuel consumption

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• Carry out a visual inspection to check the wiring
• Carefully inspect the fuel injector control module supply voltage circuit
• After that you must test the control module ground circuits with battery ground

Here are some steps which you should follow in order to diagnose this fault code:

This issue can arise due to a loose or corroded electrical connector on the injector, a fouled injector which can be dirty or plugged or a bad injector needing replacement. It is the loose or corroded connectors which are the cause of the electrical fault. There are a few cases where low voltage wiring can become shorted or open. The majority of electrical problems can be alternator related, starter solenoid wiring, oxygen sensor wiring due to the close proximity to the exhaust and battery related. The majority of electrical work connects customer-installed items such as high-power stereos and other parts or equipment installed incorrectly.

The connector on the fuel injector should be checked properly. It is a plastic connector secured to the injector with a wire clip around the connector. Pull on the connector to see if it comes off easily. Then you must remove the wire clip and pull the connector off the injector.

The harness connector should be inspected for corrosion or pushed out pins. Make sure the two blades are not bent in the injector itself. Correct any defect and apply dielectric grease and install the electrical connector.

Then you must start the car engine and listen to the injector to ensure it is working. Use a long screwdriver to the injector and the handle to your ear and you can hear it clearly. If it isn't making a highly audible 'clicking' noise, it either has no electrical power to it or it has failed.

If it is not clicking, pull the connector off the injector and check for power with a voltmeter. If there is no power, then it would mean the wiring to the fuel pump relay is at fault or has a loose connection. If it has power, probe both terminals on the harness connector and if the PCM injector driver is operating, the voltmeter will indicate rapid pulses. If you notice the pulses, then you must replace the injector.

If the injector was operating, then it is either clogged or dirty. First of all you must clean it. The kit to flush the injectors is inexpensive and will benefit the remaining injectors, possibly preventing a recurrence. If the flushing fails to solve the problem, then there is a need to replace the injector.

Common Mistakes When Diagnosing The P02F7 Code

• Problems related to wiring
• The fuel injection control module might start failing
• Failure in the fuel injector
