Error Code P02F3: What It Means & What To Do?

<<See All OBD Codes

The OBD code P02F3 can be described as Cylinder 6 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 P02F3 fault code.

When the conditions are normal, then the engine control module would turn the fuel injectors ON as well as OFF in the fuel injection system. It is the engine control module which would set this trouble code when it would detect that the fuel injector is not working as it is designed.

This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Cylinder 6 Injector Circuit Range/Performance?

• Some faults in the fuel injector 6
• The fuel injector 6 might be dirty
• The fuel injector 6 can be plugged
• The harness of fuel injector 6 might be opened or shorted
• Bad electrical connection in the fuel injector 6
• The engine control module might be malfunctioning

1. Boost Pressure Sensor - Do you remember when was the last time you got your car a Boost Pressure Sensor checked up? A damaged Boost Pressure Sensor can cause a lot of issues like displaying P02F3 code.
2. Turbocharger - Poor Turbocharger can cause a lot of difficulties, so why not get it replaced at time?
3. Knock Sensor - Are there some faults in your Knock Sensor? Don’t waste time and get them replaced or else P02F3 code can turn up.
4. Spark Plug - OBD Code P02F3 can appear because of faulty Spark Plug.
5. Intake Manifold Actuator - Everything is fine with Knock Sensor and still P02F3 code triggering? Then you must get your Intake Manifold Actuator checked.
6. Boost Pressure Gauge - There can be some issues with the Boost Pressure Gauge due to which you may see P02F3 code appearing over and over again. Visit us to buy best quality Boost Pressure Gauge online.
7. Powertrain Control Module - A lot of issues can arise do to defective Powertrain Control Module. Did you just see P02F3 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
8. Wastegate - Faulty Wastegate can be the reason why P02F3 code is flashing. Visit us to purchase top notch Wastegate online.
9. Engine Control Module - It is an important auto part which needs full care. A faulty Engine Control Module can be a reason behind the flashing up of P02F3 code.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P02F3 code by mentioning some major symptoms below:

Common Symptoms

• Illumination in the service engine soon warning light
• The overall engine performance might start decreasing
• There can be an increase in the fuel consumption

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P02F3:

• The first thing which you should do is to check the boost pressure sensor
• If you find out some defaults in the turbocharger/supercharger, then it should be definitely replaced
• Repair or replace the knock sensor
• The defective spark plug should be repaired or replaced
• The faulty engine control module should be replaced

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 shift solenoid, diesel injection, fuel injector tester and many more. Now all your problems would vanish within no time.

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

This serious issue can arise because of either 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 plugged 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 P02F3 Code

• Failure of the fuel injection control module
• The fuel injector might start failing
• There can be some issues related to wiring
