Error Code P0272: What It Means & What To Do?

<<See All OBD Codes

The definition of P0272 fault code is that there is a contribution/balance problem with cylinder #4. This code would be triggered in when the engine control module detects that the acceleration rate of the crankshaft for cylinder 4 was less than a calibrated amount. When the conditions are normal, then the engine control module would turn the fuel injectors ON and OFF in the fuel injection system.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

This fault code would mean that the powertrain control module has identified that the reference voltage in the cylinder #4’s is out of range. Generally, there is an acceptable range for this voltage in every vehicle make and model which has been already determined by the manufacturer of the vehicle. Now if the voltage would turn out to be an unacceptable amount, which would mean that either it is too high or too low.

Due to this reason, the P0272 fault code would be stored in. But yes! The problem is a lot bigger than this. If the fuel injector is not able to get the power as per it need, this would mean that its cylinder is not being given the fuel it needs. It would mean a leaner mix of the fuel. The powertrain control module would then create a mix which is much richer in the rest of the car engine. This would turn out to be a temporary solution as the overall fuel efficiency would suffer.

What causes this problem with the Cylinder 4 Contribution/Balance Fault?

• There can be some damage in the fuel injector
• Some faults in the wiring or connectors that run to cylinder #12’s fuel injector.
• Defects in the powertrain control module
