The factors influencing the cost of diagnosing and fixing the automobile fault code P10C9 are the estimated repair time of 1.0 hour and the typical hourly rate charged by auto repair shops, which ranges from $75 to $150.

The P10C9 fault code refers to a problem with the Intake-Air Temperature Sensor in the engine. The Engine Control Module (ECM) is responsible for monitoring this sensor. When the Intake-Air Temperature Sensor is not functioning within the factory specifications, the ECM will set the P10C9 code.

This code specifically indicates that the intake air temperature during a cold start is too high on a particular bank of the engine. In simpler terms, the P10C9 fault code means that there is an issue with the sensor that measures the temperature of the air entering the engine. This problem occurs specifically during a cold start, when the engine is just being turned on.

The code indicates that the temperature reading on one side of the engine is higher than it should be.

This can affect the engine’s performance and may require attention to prevent further damage.

What are the possible causes for the automobile fault code P10C9?

If you see the engine light or service engine soon warning light on, the fault code P10C9 could be the culprit. This code is often caused by a faulty intake-air temperature sensor, an open or shorted sensor harness, or a poor electrical connection in the 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 more comprehensive solution.
