The factors that influence the cost of fixing the automobile fault code P3102 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 hourly rate charged by most auto repair shops ranges between $75 and $150 per hour. These factors will determine the total cost of fixing the P3102 fault code.

The P3102 fault code relates to the solenoid-controlled injection valve in cylinder 1.

This valve discharges a high-pressure spray into the combustion 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+.

This can cause issues with fuel injection and lead to problems with emissions and fuel consumption.

What are the possible causes of the P3102 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P3102 fault code. This code is usually caused by a faulty fuel injector 1, an open or shorted fuel injector 1 harness, a poor electrical connection in the fuel injector 1 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.
