The P145C fault code indicates a problem with the fuel tank pressure sensor.

This sensor is responsible for monitoring the pressure in the fuel tank. When the fuel vapor is stored in the evaporative emission (EVAP) system, it is introduced into the engine through the EVAP canister purge valve. The PCM controls the amount of vapor introduced by adjusting the duty cycle to the EVAP canister purge valve based on the engine’s condition.

However, if the fuel tank pressure sensor detects a range or performance issue, it means that there is a problem with accurately measuring the pressure in the fuel tank. This can lead to issues with fuel efficiency and emissions.

It is important to address this fault code promptly to ensure proper functioning of the EVAP system and overall engine performance.

What are the possible causes for the automobile fault code p145c?

If you see the engine light or service engine soon warning light on, the fault code P145C could be the culprit. This code is often caused by a faulty fuel tank pressure (FTP) 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.

How can I visually inspect the wiring harness and connectors to fix the p145c fault code?

If you’re dealing with the p145c fault code and your engine light is on, it’s time to take action. The most likely cause is a faulty Fuel Tank Pressure (FTP) Sensor or issues with the sensor’s wiring harness and connectors. To fix this, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This simple step can help you identify and resolve the issue.

What should I look for when checking for damaged components and corroded connector’s pins to resolve the p145c fault code?

When resolving the P145C fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins. These issues can cause a poor electrical connection or an open/short circuit in the Fuel Tank Pressure (FTP) Sensor. By thoroughly examining these areas, you can identify and address any problems that may be triggering the engine light or service engine soon warning light.
