The P130B fault code refers to the Knock Sensor 4 Circuit in an automobile’s engine. The Knock Sensor is equipped with a piezo crystal that detects vibrations caused by combustion knock.

This sensor converts these vibrations into an electrical signal, which is then used by the Engine Control Module (ECM) to adjust ignition timing and restore normal combustion in the affected cylinder. The ECM constantly monitors the Knock Sensor and if it deviates from factory specifications, it triggers the P130B fault code.

This code indicates a potential issue with the Knock Sensor circuit that needs to be addressed.

What are the possible causes of the automobile fault code P130B?

If you see the engine light or service engine soon warning light on, the fault code P130B could be the culprit. This code is often caused by a faulty knock sensor, an open or shorted knock sensor harness, or a poor electrical connection in the knock sensor circuit. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes listed above for a comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the P130B fault code?

To fix the P130B fault code, start by visually inspecting the wiring harness and connectors.
