The P165A fault code is related to the Electronic Immobilizer system in your vehicle.

Specifically, it indicates a problem with the interface between the Electronic Immobilizer (EWS) and the Engine Control Module (ECM) hardware.

The Digital Motor Electronics (DME) in your vehicle constantly monitors the EWS to ensure it is functioning within the factory specifications. When the DME detects that the EWS is not operating correctly, it sets the P165A fault code. This code serves as a warning that there may be an issue with the communication between the EWS and the ECM hardware.

It is important to address this fault code promptly to ensure proper functioning of the immobilizer system and prevent any potential starting or security issues with your vehicle.

What are the possible causes of the automobile fault code p165a?

If you see the engine light or service engine soon warning light on, the fault code P165A could be the culprit. This code is often caused by a faulty Digital Motor Electronics (DME), an open or shorted DME harness, a poor electrical connection in the DME circuit, or an issue with the Electronic Immobilizer (EWS) data. To fix this problem, 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.

How can I visually inspect the wiring harness and connectors to fix the fault code p165a?

If you’re dealing with the fault code p165a and your engine light is on, it’s time to visually inspect the wiring harness and connectors.
