<<See All OBD Codes

The P0278 is a trouble code which can be defined as Cylinder 6 Contribution/Balance Fault. This code would represent an unusual amount of voltage being detected in the vehicle’s fuel injector circuit.

The P0278 is a fault code which would start appearing when the powertrain control module would detect an amount of voltage in the fuel injector circuit which is outside the specifications of the manufacturer. This fault code would only apply to the V6 vehicles. The voltage variations which would exceed the voltage which has been specified by the manufacturer which is 10% will cause the P0278 fault code to get stored in the powertrain control module and will cause the check engine light to start illuminating.

What causes this problem with the Cylinder 6 Contribution/Balance Fault?

• Some faults in the vehicle’s fuel injector. If the fifth cylinder isn’t creating as much power as the others, then it’s probably due to a lack of fuel.
• An electrical problem can cause the fuel injector to lack power
• Dirt, debris or some other contaminant could have gotten on the fuel injector inlet filter too

1. Fuel Injector - Defective car Fuel Injector can be a major reason why P0278 code depicts. So make sure to replace it with new fuel injector online so that you don’t have to face any further issues.
2. Fuel System - Everything is okay with the Crankshaft Sensor and still OBD code P0278 triggering? Then there must be some defects in Fuel System. Replace them as soon as possible.
3. Crankshaft Sensor - P0278 code flashing? Get your Crankshaft Sensor inspected from a mechanic.
4. Lifters - If everything is alright with Fuel Injector, then there is surely some defect in Lifters. Get it replaced before the situation gets worse.
5. Camshaft Sensor - P0278 code can display due to some issues in the Camshaft Sensor. So it is very important to replace the Cam with us at equitable prices.
6. Piston Rings - Do you remember when was the last time you got your car Rings checked up? A faulty Piston Ring can cause a lot of issues like displaying P0278 code.
7. Cylinder Head Gasket - Are there some faults in your Cylinder Head Gasket? Don’t waste time and get them replaced or else P0278 code can turn up.
8. Engine Control Module - OBD Code P0278 can appear because of faulty Engine Control Module. 

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• The vehicle might sustain a rough idle
• There can be bad fuel economy
• The vehicle might start suffering from poor acceleration or power
• The check engine light might be turned on
• Powertrain control module might be defective

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:

• Cleaning the fuel injector may be all it takes to fix this problem
• You can always replace the fuel injector if it’s become too damaged to repair

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 rims, fuel wheels, hydraulic cylinder 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:

• The mechanic should use an OBD-II scanner should so that he can download all codes that have been stored by the powertrain control module
•  You must address all these problems, not just P0278, as they could be related
• After that the fuel injector should be inspected by the mechanic. The harness side may be corroded or have pins that have been pushed out. The pins which are bent would also indicate problem
• The next step would be to start the car engine
• You can put the end of a long screwdriver to the injector and then place your ear on the handle to listen for the characteristic “ticking” sound which would indicate that the engine is running normally.
• On the other hand, if you are not able to hear this sound, then there is definitely some issue with the injector as it might have failed

Common Mistakes When Diagnosing The P0278 Code

• Failure in the fuel injection control module
• The fuel injector can start to fail
• Issues in the powertrain control module
• Some issues related to the wiring
