  • 4.
  • Check for broken, bent, pushed out, or corroded pins in the connectors.
  • 5.
  • Repairing this fault code is estimated to take approximately 1.0 hour.

The factors influencing the diagnosis and fixing cost of the automobile fault code p1318 are the estimated repair time and the hourly rate charged by auto repair shops. The estimated repair time for this fault code is 1.0 hour.

Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p1318 fault code.

The P1318 fault code refers to a problem with the Anti-Lock Brake System (ABS).

The ABS uses sensors to detect if the vehicle is on a rough surface that could cause a false misfire detection. When the Engine Control Module (ECM) determines that the surface is rough enough to potentially create a misfire signal, it disables the misfire detection to prevent false Diagnostic Trouble Codes (DTCs).

Specifically, the P1318 code indicates that the ABS rough road signal line is stuck at battery voltage.

This means that there is an issue with the signal line that is responsible for transmitting information about rough road conditions to the ECM. The line is stuck at battery voltage, which can prevent the ECM from accurately determining if the vehicle is on a rough surface. This can lead to false misfire detections and potentially trigger the P1318 fault code.

What are the possible causes of the automobile fault code P1318?

If you see the engine light or service engine soon warning light on, the fault code P1318 could be the culprit. This code is often caused by a faulty ABS speed sensor, an open or shorted ABS speed sensor harness, a poor electrical connection in the ABS speed sensor circuit, or a faulty Engine Control Module (ECM). To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or broken, bent, pushed out, or corroded pins. Don’t forget to also address the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the P1318 fault code?

To fix the P1318 fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify any issues with the ABS Speed Sensor or poor electrical connections. Don’t forget to check the other possible causes listed above as well.

What should I look for when checking for damaged components and connector’s pins to resolve the P1318 fault code?

When resolving the P1318 fault code, start by checking for damaged components and connector’s pins. Visually inspect the related wiring harness and connectors, looking for any signs of damage such as broken, bent, pushed out, or corroded pins. This can help identify if there is a faulty ABS Speed Sensor, an open or shorted ABS Speed Sensor harness, a poor electrical connection in the ABS Speed Sensor circuit, or a faulty Engine Control Module (ECM). By addressing these possible causes, you can effectively fix the issue and clear the Engine Light or Service Engine Soon Warning Light.

p1318 error fault code explained

If your engine light is on and you’re seeing the P1318 fault code, it could be due to a faulty ABS speed sensor, an open or shorted ABS speed sensor harness, a poor electrical connection in the ABS speed sensor circuit, or a faulty Engine Control Module (ECM). To fix this issue, visually inspect the wiring harness and connectors, check for damaged components, and look for any broken, bent, pushed out, or corroded connector pins.
