[SOLVED] P1613 Code: Mil Request Signal Circuit High Input – How To Fix It!

Are you wondering what the automobile fault code P1613 means?

Well, when you see the Engine Light ON or the Service Engine Soon Warning Light, it could be indicating a faulty Malfunction Indicator Light (MIL).

Other possible causes include an open or shorted MIL harness, poor electrical connection in the MIL circuit, or a faulty Engine Control Module (ECM). To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Look out for broken, bent, pushed out, or corroded connector pins.

The repair time for this problem is estimated to be around 1.0. So, if you encounter this fault code, make sure to address it promptly to avoid any further complications.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1613 fault code.

  • The symptoms of the automobile fault code p1613 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1613 can be caused by a faulty Malfunction Indicator Light (MIL), an open or shorted MIL harness, a poor electrical connection in the MIL circuit, or a faulty Engine Control Module (ECM).

  • The fault code p1613 can be caused by a faulty Malfunction Indicator Light (MIL), an open or shorted MIL harness, a poor electrical connection in the MIL circuit, or a faulty Engine Control Module (ECM).

To fix the p1613 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1613, you need to follow these steps: 1.
  • Check the possible causes mentioned above.
  • 2.
  • Visually inspect the wiring harness and connectors related to the fault code.
  • 3.
  • Look for any damaged components.
  • 4.
  • Check for broken, bent, pushed out, or corroded pins in the connectors.
  • The estimated repair time for this fix is 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p1613 are the estimated repair time of 1.0 hour and the typical auto repair shop charges of $75 to $150 per hour.

The P1613 fault code is triggered when the Engine Control Module (ECM) receives a request to turn on the engine light and sets this code.

This happens when there is an issue with a system other than the engine control. The code specifically refers to the MIL (Malfunction Indicator Lamp) Request Signal Circuit having a high input. In simpler terms, it means that there is a problem with the communication between the ECM and other control units in the vehicle.

This fault code helps identify and diagnose issues in non-engine control systems.

What are the possible causes for the automobile fault code p1613 and how can I visually inspect them?

If you’re seeing the fault code P1613 and your engine light is on, there are a few possible causes to consider. It could be a faulty Malfunction Indicator Light (MIL), an open or shorted MIL harness, a poor electrical connection in the MIL circuit, or even a faulty Engine Control Module (ECM). To visually inspect these potential issues, check the wiring harness and connectors related to the MIL. Look for any damaged components and examine the connector’s pins for any signs of being broken, bent, pushed out, or corroded.

How can a faulty Malfunction Indicator Light (MIL) lead to the engine light being ON and what steps can I take to fix it?

If you notice that your engine light is ON or you see a Service Engine Soon Warning Light, it could be due to a faulty Malfunction Indicator Light (MIL). This can happen if the MIL harness is open or shorted, there is a poor electrical connection in the MIL circuit, or if the Engine Control Module (ECM) is faulty. To fix this issue, you should check the possible causes mentioned above. Take a close look at the wiring harness and connectors, inspect for any damage or broken components, and check for any bent, pushed out, or corroded pins in the connectors.

What should I do if I suspect a poor electrical connection in the MIL circuit causing the p1613 fault code and how can I check for damaged components or connector issues?

If you suspect a poor electrical connection in the MIL circuit causing the p1613 fault code, there are a few steps you can take to check for damaged components or connector issues. First, visually inspect the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded connector pins. This can often be the cause of a poor electrical connection. By checking these possible causes, you can identify and fix the issue, ensuring that your engine light stays off and your vehicle runs smoothly.
