The automobile fault code P3105 can be diagnosed and fixed in an estimated repair time of 1.0 hour. The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of fixing the P3105 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P3105 fault code is related to the solenoid-controlled injection valve in the combustion chamber. This valve discharges a high-pressure spray of fuel into the chamber.

The fault code is triggered when there is a short circuit to ground in the low voltage side of the fuel injector for cylinder 2. This fault code can cause issues with fuel consumption and pollutant emissions.

It is important to address this issue promptly to ensure proper functioning of the fuel injection system.

What are the possible causes of the P3105 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P3105 fault code. This code is usually caused by a faulty fuel injector 2, an open or shorted fuel injector 2 harness, a poor electrical connection in the fuel injector 2 circuit, or a faulty digital motor electronics (DME). To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
