The P06A8 fault code refers to a problem with the Sensor Reference Voltage ‘C’ Circuit RangePerformance. This code indicates that there is an issue with the control module’s internal 5-volt reference buses.

These reference buses provide a 5-volt reference circuit for multiple sensors. If there is a fault condition on one 5-volt reference circuit, it can affect the other circuits connected to the reference bus. The control module constantly monitors the voltage on these reference buses to ensure they are functioning properly.

What are the possible causes for the automobile fault code P06A8?

If you see the engine light on or the service engine soon warning light, the fault code P06A8 could be the culprit. This code is often caused by a faulty Engine Control Module (ECM), an open or shorted ECM harness, a poor electrical connection in the ECM circuit, or a shorted sensor on the 5 volt circuit. To fix this 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 mentioned above.

How can I visually inspect the wiring harness and connectors to fix the P06A8 fault code?

If you’re dealing with the P06A8 fault code and your engine light is on, it’s time to visually inspect the wiring harness and connectors. This fault code can be caused by a faulty Engine Control Module (ECM), an open or shorted ECM harness, a poor electrical connection in the ECM circuit, or a shorted sensor on the 5 volt circuit. To fix it, check the possible causes mentioned earlier and visually inspect the wiring harness and connectors. Look out for damaged components and check for broken, bent, pushed out, or corroded connector pins.

What should I look for when checking for damaged components and connector pins to resolve the P06A8 fault code?
