If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to the p118e fault code.

  • The symptoms of the automobile fault code P118E include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code P118E can be caused by a faulty exhaust gas temperature sensor, open or shorted sensor harness, poor electrical connection in the sensor circuit, or a faulty engine control module (ECM).

  • The fault code P118E can be caused by: a faulty Exhaust Gas Temperature Sensor, an open or shorted Exhaust Gas Temperature Sensor harness, a poor electrical connection in the Exhaust Gas Temperature Sensor circuit, or a faulty Engine Control Module (ECM).

To fix the automobile fault code p118e, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P118E, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • The estimated repair time for this fix is 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code P118E based on the estimated repair time of 1.0 hour include the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P118E fault code refers to the performance of the exhaust gas temperature sensor 1 while the engine is running.

This sensor is a variable resistor that measures the temperature of the exhaust gas. It is the first sensor on the exhaust system, with subsequent sensors counted from the engine outlet to the end of the exhaust system.

The Engine Control Module (ECM) supplies 5 V to the exhaust gas temperature signal circuit and provides a ground to the low reference circuit.

The information from the exhaust gas temperature sensor is used by the ECM during the exhaust gas particulate filter cleaning process.

If the ECM detects that the difference between the measured exhaust gas temperature and the estimated exhaust gas temperature is greater than a calibrated amount for more than 1 second, it will set the Diagnostic Trouble Code (DTC) P118E. This code indicates a performance issue with the exhaust gas temperature sensor 1 while the engine is running.

What are the possible causes of the automobile fault code P118E?

If you’re seeing the engine light or service engine soon warning light, the fault code P118E could be the culprit. This code is often caused by a faulty exhaust gas temperature sensor, an open or shorted sensor harness, a poor electrical connection in the sensor circuit, or a faulty engine control module (ECM). 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 P118E fault code?

To fix the P118E fault code, 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 can help identify any issues with the Exhaust Gas Temperature Sensor or poor electrical connections. Don’t forget to also check the other possible causes listed above.

What should I look for when checking for damaged components and connector pins to resolve the P118E fault code?

When resolving the P118E fault code, start by checking for damaged components and connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded connector pins. By doing this, you can identify any issues that may be causing the fault code and take the necessary steps to fix them.
