[SOLVED] P117F Code: Oxygen Sensor Rich Control Limit Exceeded – Fix It Now!

If you see the engine light on or the service engine soon warning light, it could be due to the automobile fault code: p117f. This code is typically caused by a faulty oxygen sensor, an open or shorted oxygen sensor harness, a poor electrical connection in the oxygen sensor circuit, a cylinder misfire, or a richlean air fuel ratio.

To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damaged components or broken, bent, pushed out, or corroded connector pins. The repair time for this code is estimated to be around 1.0.

Make sure to check the “Possible Causes” listed above and take appropriate action.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p117f fault code.

  • The symptoms of the automobile fault code p117f include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p117f can be caused by a faulty oxygen sensor, open or shorted sensor harness, poor electrical connection, cylinder misfire, or richlean air fuel ratio.

  • The fault code P117F can be caused by a faulty oxygen sensor, an open or shorted oxygen sensor harness, a poor electrical connection in the oxygen sensor circuit, a cylinder misfire, or a rich/lean air fuel ratio.

To fix the automobile fault code p117f, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p117f, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded pins in the connectors.
  • This fix should take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p117f 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 P117F fault code refers to the Bank 4 Oxygen Sensor Correction Behind Converter Rich Control Limit Ex.

This means that the Engine Control Module (ECM) is monitoring the oxygen sensor in Bank 4 of the vehicle’s engine. If the oxygen sensor is not operating within the factory specifications, the ECM will set this fault code. The purpose of the oxygen sensor is to measure the amount of oxygen in the exhaust gases.

This information is used by the ECM to adjust the air-fuel mixture for optimal engine performance and fuel efficiency.

When the oxygen sensor in Bank 4 is not functioning properly, it can lead to a rich air-fuel mixture, meaning there is too much fuel and not enough oxygen.

This can result in decreased fuel efficiency and increased emissions. To fix this issue, the oxygen sensor in Bank 4 will need to be inspected and potentially replaced if it is found to be faulty. It is important to address this fault code promptly to ensure the engine is running at its best and to prevent further damage to the vehicle’s emissions system.

What are the possible causes of the automobile fault code P117F?

If you see the engine light or service engine soon warning light on, the fault code P117F could be the culprit. This code is often caused by a faulty oxygen sensor, an open or shorted oxygen sensor harness, a poor electrical connection in the oxygen sensor circuit, a cylinder misfire, or a rich/lean air fuel ratio. 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.

How can I visually inspect the wiring harness and connectors to fix the P117F fault code?

To fix the P117F fault code, start by checking the possible causes mentioned above. Then, visually inspect the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins in the connectors. This thorough inspection will help identify any issues with the oxygen sensor or its circuit, cylinder misfire, or air fuel ratio.

What should I look for when checking for damaged components and connector pins to resolve the P117F fault code?

To resolve the P117F 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 pins. This can help identify any issues with the oxygen sensor or its circuit. Additionally, check for cylinder misfires and a rich/lean air fuel ratio, as these can also be potential causes. By thoroughly examining these possible causes, you can effectively address the issue and clear the engine light or service engine soon warning light.

p117f error fault code explained

If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to a faulty Oxygen Sensor, open or shorted Oxygen Sensor harness, poor electrical connection in the Oxygen Sensor circuit, cylinder misfire, or a richlean air fuel ratio. To fix this, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
