[SOLVED] P114C Code: Fixing Rich Fuel Trim In Bank 2 Oxygen Sensor System

The automobile fault code P114C indicates a potential issue with the exhaust system or oxygen sensors. The symptom is an illuminated Engine Light or Service Engine Soon Warning Light.

Possible causes include a leak in the exhaust system, faulty pre or post-catalyst oxygen sensors, open or shorted sensor harness, poor electrical connection, or a faulty Digital Motor Electronics (DME). To fix the problem, visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Look for broken, bent, pushed out, or corroded pins in the connectors. The repair time for this issue is estimated at 1.0.

It is important to address this fault code promptly to prevent further damage to the vehicle.

If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to the p114c fault code.

  • The symptoms of the automobile fault code P114C include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p114c can be caused by a leak in the exhaust system, faulty oxygen sensors, or issues with the electrical connections or Digital Motor Electronics (DME).

  • The fault code P114C can be caused by a leak in the exhaust system, a faulty pre-catalyst or post-catalyst oxygen sensor, an open or shorted harness for the oxygen sensor, a poor electrical connection in the oxygen sensor circuit, or a faulty digital motor electronics (DME).

To fix the automobile fault code p114c, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p114c, 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.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the cost of diagnosing and fixing the automobile fault code p114c 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 P114C fault code is related to the lambda closed-loop mixture control in your vehicle. The Engine Control Module (ECM) sets this code when the mixture control is not within the factory specifications.

Specifically, the code indicates that the post-catalyst fuel trim via the oxygen sensor system is too rich in Bank 2 of the engine. This fault code suggests that there is an issue with the fuel mixture after the catalytic converter in one of the engine banks.

The ECM detects that the fuel trim is too rich, meaning there is an excess of fuel in the mixture. This can lead to poor fuel efficiency and increased emissions. It is important to address this issue promptly to ensure optimal engine performance and reduce environmental impact.

A qualified mechanic can diagnose the exact cause of the problem and recommend the necessary repairs or adjustments to resolve the P114C fault code.

What are the possible causes of the automobile fault code p114c?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P114C could be the culprit. This code can be caused by a few different things, including a leak in the exhaust system, a faulty pre-catalyst or post-catalyst oxygen 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 accurate diagnosis.
