When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p118f fault code.

  • The symptoms of the automobile fault code P118F include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code P118F can be 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).

  • The fault code P118F can be caused by: a faulty exhaust gas temperature sensor, an open or shorted harness for the exhaust gas temperature sensor, a poor electrical connection in the exhaust gas temperature sensor circuit, or a faulty engine control module (ECM).

To fix the automobile fault code p118f, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P118F, 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 automobile fault code P118F can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of the repair will depend on the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

The P118F fault code refers to the performance of the exhaust gas temperature sensor 2 while the engine is running.

Exhaust gas temperature sensors are variable resistors that measure the temperature of the exhaust gas.

The first exhaust temperature sensor is located at the engine outlet, and subsequent sensors are counted upwards towards the end of the exhaust system. The Engine Control Module (ECM) supplies 5V to the exhaust gas temperature signal circuit and provides a ground to the low reference circuit. During the exhaust gas particulate filter cleaning process, the ECM uses the temperature information from the exhaust gas temperature sensor.

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, the P118F fault code will be set. This fault code indicates a potential issue with the performance of the exhaust gas temperature sensor 2 while the engine is running.

What are the possible causes of the automobile fault code P118F?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P118F might 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 even a faulty engine control module (ECM). To fix this issue, start by visually inspecting the wiring harness and connectors. Look out for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the P118F fault code?

To fix the P118F 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 P118F fault code?

When resolving the P118F fault code, start by checking for damaged components and connector pins. Visually inspect the wiring harness and connectors for any signs of damage. Look for broken, bent, pushed out, or corroded pins on the connectors. This can help identify any issues with the Exhaust Gas Temperature Sensor or its circuit. By addressing these potential causes, you can effectively fix the problem and clear the Engine Light or Service Engine Soon Warning Light.

p118f error fault code explained

If your engine light is on, it could be due to a faulty Exhaust Gas Temperature Sensor or issues with the sensor’s wiring. To fix this, visually inspect the wiring harness and connectors for any damage.

Check for broken, bent, pushed out, or corroded pins on the connectors.
