If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of u0116 fault code. Here are the symptoms to look out for:

  • The automobile fault code u0116 has the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The u0116 fault code can be caused by a faulty module, open or shorted harness, or poor electrical connection.

  • The automobile fault code u0116 can be caused by a faulty Coolant Temperature Control Module.
  • It can also be caused by an open or shorted Coolant Temperature Control Module harness.
  • Additionally, a poor electrical connection in the Coolant Temperature Control Module circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code u0116, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u0116, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code U0116 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the U0116 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The U0116 fault code is related to the Controller Area Network (CAN) in a vehicle. CAN is a bus standard that connects automotive devices without a host computer.

CAN uses two wires for communication, CAN high and CAN low. When the CAN bus is idle, both lines carry 2.5V.

The U0116 code sets when the Coolant Temperature Control Module does not send a periodic message.

This code indicates that there is a communication problem between the module and the CAN bus. The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise, so the problem is likely related to the module or the wiring.

What are the possible causes of the u0116 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u0116 fault code. This code is usually caused by a faulty coolant temperature control module, an open or shorted harness, or poor electrical connection in the coolant temperature control module circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the u0116 fault code?

If you’re experiencing the u0116 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Coolant Temperature Control Module or an open or shorted harness. To fix this issue, you should visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify any issues and allow you to take the necessary steps to fix the problem.

What are the signs of damaged components or broken, bent, pushed out, or corroded connector’s pins that I should look for when fixing the u0116 fault code?

If you’re fixing the u0116 fault code, keep an eye out for the engine light being on or the service engine soon warning light. The cause could be a faulty coolant temperature control module, an open or shorted harness, or a poor electrical connection. To fix it, check the possible causes and visually inspect the wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
