P0295 Cylinder 12 Injector Circuit High Code

P0295 – OBD-II Trouble Code Technical Description

Cylinder No. 12 Injector Circuit High Signal

What does the fault code mean P0295?

Possible reasons

This DTC P0295 can occur due to the following reasons:

1. The electrical harness from the PCM to the injector is faulty.
2. Defective electrical connector on the fuel injector.
3. Internal shorted fuel injector causing high voltage consumption.
4. Clogged or dirty fuel injector.
5. Malfunction of the fuel injection control module (FICM).
6. Fuel injector malfunction.
7. Malfunction of the powertrain control module (PCM).
8. Wiring problem.
9. Faulty or restricted fuel injector.
10. The fuel injector wiring is damaged.
11. The engine control module is faulty.
12. Loose connection between injector and cylinder 12.

Eliminating the problem requires diagnosing and solving the specific cause based on the identified factors.

What are the symptoms of a fault code? P0295?

Symptoms of a P0295 code include:

1. The malfunction indicator will illuminate and a P0295 code will set.
2. Poor engine idling.
3. Deteriorating fuel economy.
4. Lack of power and poor acceleration.
5. Inconsistent acceleration.
6. Fluctuations in engine speed.
7. Reduced engine performance.
8. Increased fuel consumption.

If you notice these symptoms, it is recommended that you check your engine light and run diagnostics to resolve the issue.

How to diagnose a fault code P0295?

To resolve the P0295 code, follow these steps:

1. Check the electrical connector at the fuel injector, looking for bent or pushed out pins. Apply dielectric grease and make sure the connector is firmly seated.
2. Check the injector for functionality. Start the engine and listen to the injector sound using the long handle of a screwdriver. A good injector should make a clicking sound.
3. Disconnect the fuel injector and check the resistance between the contacts. Normal resistance should be between 0,5 and 2,0 ohms. If the resistance is different, this may indicate an internal shorting of the injector.
4. If the injector is not working properly after cleaning, consider replacing the injector. Use a direct injection cleaning kit for the cleaning procedure.
5. If the P0295 code recurs after all of the above steps, the injector may need to be replaced.
6. Perform a visual inspection of the injector circuit and cylinder 12 injector to ensure proper connection and no damage to the wiring.
7. Check the fuel injectors with an OBD2 scanner to ensure the correct reference voltage.
8. If the cylinder 12 injector readings are abnormal, replace the faulty injector.
9. Check ECM operation and discuss the results with the customer if the fuel injector is operational and the P0295 code is still active.

Diagnostic errors

A common mistake when diagnosing a P0295 code is replacing the fuel injector without first checking it. It is important to look at the problem comprehensively, because despite the injector being mentioned in the code, the most common cause is damaged wiring.

How serious is the fault code? P0295?

The P0295 code can cause serious driving problems, including loss of power and poor acceleration, which can be frustrating and even lead to delays. Therefore, it is important to diagnose and fix this problem as soon as possible.

What repair will help eliminate the code? P0295?

• Replace the fuel injector in cylinder 12.
• Repair or replace the wiring associated with the injector circuit in cylinder 12.
• Replace the ECM (engine control module) if necessary.
• Clean the fuel system.
• Connect the fuel injector connector in cylinder 12 (if it was disconnected).

P0295 – Brand-specific information

Trouble code P0295 can be found on different makes and models of vehicles. Diagnosis and repair of this problem may vary slightly depending on the vehicle manufacturer. If this error occurs, it is recommended to contact certified service centers or specialists who specialize in the brand of your car. They have the experience and knowledge necessary to accurately diagnose and correct the problem. However, it is important to follow the recommendations provided by your vehicle manufacturer regarding diagnosing and repairing the P0295 code.

It is important to be careful when problems arise with your engine fuel system. If repairs are necessary, the mechanic should wear safety glasses and keep all sources of ignition away from the vehicle. This is important because during diagnosis or repair of the fuel system, it may remain open and fuel may leak into the environment.
