P0295 Code Definition

Cylinder 12 Injector Circuit High

What the P0295 code means

The P0295 trouble code means that the Engine Control Module (ECM) detects resistance in the cylinder 12 fuel injector circuit as falling outside the normal range of specifications set by the manufacturer. This excessive resistance causes the reference voltage of the injector on cylinder 12 to change and therefore causes the injector to perform improperly.

What are the causes of the P0295 code?

  • A faulty or restricted fuel injector
  • Damaged fuel injector wiring
  • A faulty Engine Control Module
  • A loose connection to the cylinder 12 fuel injector

What are the symptoms of the P0295 code?

  • Inconsistent acceleration
  • Loss of power
  • Hesitation
  • Check Engine Light illumination
  • Rough idle

How does a mechanic diagnose the P0295 code?

  • Performs a visual inspection of the cylinder 12 injector circuit while making sure that the injector on cylinder 12 is properly connected and the wiring is not damaged

  • Checks the fuel injector itself for any visual damages

  • If nothing is visibly wrong with the fuel injector, uses an OBD2 scanner to check the fuel injectors to verify whether they are producing the correct reference voltage (particular attention paid to the cylinder 12 injector)

If the cylinder 12 injector is not reading correctly but all other injectors seem fine, the signs are pointing towards a faulty injector.

  • Uses the manufacturer’s recommended procedure for testing a fuel injector

  • If the fuel injector fails this test, replaces it at the customer’s request

If the fuel injector is not clogged or faulty, the mechanic should test the ECM for proper function and discuss the data that was found with the customer

Common mistakes when diagnosing the P0295 code

A common mistake that could be made when diagnosing the P0295 trouble code would be to replace the fuel injector without checking it first. It is very important to see the issue at hand from all angles when determining the correct repair. Although the fuel injector in the cylinder 12 circuit is mentioned in the trouble code, the most common cause of this trouble code is actually damaged wiring.

How serious is the P0295 code?

The P0295 code is relatively high on the seriousness scale. This code can cause serious drivability issues that would be quite unpleasant to the driver, such as causing a person to be late to work due to loss of power. It would be wise to have this issue diagnosed and repaired as soon as possible.

What repairs can fix the P0295 code?

  • Replacing the fuel injector on the cylinder 12 circuit
  • Repairing or replacing wiring that is associated with the cylinder 12 injector circuit
  • Replacing the ECM
  • Performing a fuel system cleaning
  • Reconnecting the connector to the fuel injector on cylinder 12 (if only unplugged)

Additional comments regarding the P0295 code?

It is always a good idea to be very cautious when dealing with fuel issues on an engine. If a driver would like to watch the mechanic fix this issue, it is very important to wear safety glasses and keep all sources of ignition away from the vehicle during the repair. This is due to the fact that the fuel system may be opened up during the diagnosis or repair, and fuel can become airborne.
