The factors that influence the cost of fixing the automobile fault code P3114 are the estimated repair time and the hourly rate charged by the auto repair shop.

The estimated repair time for this fault code is 1.0 hour. The cost of repair is commonly charged between $75 and $150 per hour by most auto repair shops. These factors play a crucial role in determining the overall cost of fixing the P3114 fault code.

The P3114 fault code relates to the solenoid-controlled injection valve in the combustion chamber.

This valve discharges a high-pressure spray of fuel into the chamber. The DME diagnosis monitors the activation of the low voltage side of the fuel injector.

The fault code is detected when there is a short circuit to B+ in the cylinder 4 high-pressure fuel injector low side circuit.

What are the possible causes of the P3114 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P3114 fault code. This code is usually caused by a faulty fuel injector 4, an open or shorted fuel injector 4 harness, a poor electrical connection in the fuel injector 4 circuit, or a faulty digital motor electronics (DME). To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P3114 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P3114 fault code, there are a few possible causes to consider. One of them is a faulty Fuel Injector 4, which could be caused by an open or shorted harness, poor electrical connection, or a faulty Digital Motor Electronics (DME).
