The P16C5 fault code refers to a problem with the engine mount actuator control power circuit.

This circuit is responsible for controlling the engine mounts electronically.

The engine mount control system consists of the engine mount actuators, the engine mount control unit, and the Powertrain Control Module (PCM).

The engine mount control unit uses sensor outputs from the crankshaft and camshaft position sensors to estimate engine vibration. It then sends signals to the engine mount actuators to counteract this vibration by pushing and pulling on the engine. If the engine mount control unit voltage falls below a certain value for a set period of time, it indicates a malfunction and triggers the P16C5 fault code.

This code is stored as a diagnostic trouble code (DTC) for further analysis and repair.

What are the possible causes for the automobile fault code p16c5?

If you see the engine light on or the service engine soon warning light, the fault code P16C5 could be the culprit. This code is often caused by a faulty engine mount actuator, an open or shorted harness, a poor electrical connection in the actuator circuit, or a faulty engine mount control unit. 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 mentioned above.

How can I visually inspect the wiring harness and connectors to fix the issue?

To fix the issue of the Engine Light being ON, 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 will help identify if the issue lies with a faulty Engine Mount Actuator, an open or shorted harness, a poor electrical connection in the circuit, or a faulty Engine Mount Control Unit. Take note of the possible causes mentioned and proceed with the necessary repairs.

What should I look for when checking for damaged components or corroded connector pins?

When troubleshooting a symptom like the Engine Light ON, it’s important to consider potential causes like a faulty Engine Mount Actuator or poor electrical connections. To check for damaged components or corroded connector pins, visually inspect the related wiring harness and connectors. Look for any signs of broken, bent, pushed out, or corroded pins. This step is crucial in identifying and resolving the issue effectively.
