  • The automobile fault code P3158 can be caused by a faulty fuel injector 4.
  • It can also be caused by an open or shorted fuel injector 4 harness.
  • Another cause can be a poor electrical connection in the fuel injector 4 circuit.
  • Lastly, a faulty digital motor electronics (DME) can also trigger this fault code.

Below are the possible fixes for the automobile fault code p3158, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p3158, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P3158 can be diagnosed and fixed within 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 P3158 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The P3158 fault code indicates a problem with the high-pressure fuel injector in cylinder 4. The solenoid-controlled injection valve discharges a high-pressure spray into the combustion chamber.

The fuel is injected into the combustion chambers under high pressure during the intake and compression strokes. The DME diagnosis monitors the activation of the high voltage side of the fuel injector. The DTC is detected when there is a short circuit to ground.

What are the possible causes of the P3158 automobile fault code?

The P3158 automobile fault code is triggered when the Engine Light or Service Engine Soon Warning Light turns on. The possible causes of this fault code include 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, one 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.
