  • The fault code P118A can be caused by several factors, including exhaust leaks, a faulty oxygen sensor, an open or shorted oxygen sensor harness, and a poor electrical connection in the oxygen sensor circuit.

To fix the automobile fault code p118a, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P118A, first, check 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 P118A 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 P118A fault code is related to the Oxygen Sensor in the engine. The Engine Control Module (ECM) constantly monitors the Oxygen Sensor to ensure it is functioning properly.

When the Oxygen Sensor does not meet the factory specifications, the ECM sets the P118A code. This code specifically refers to Bank 3 Probe 1, indicating that there is an issue with the voltage being too low. This low voltage can result in a leakage problem.

It is important to address this fault code promptly to ensure optimal engine performance and fuel efficiency.

What are the possible causes of the automobile fault code P118A?

If you see the engine light or service engine soon warning light on, the fault code P118A could be the culprit. This code can be caused by a few different things, including exhaust leaks, a faulty oxygen sensor, an open or shorted oxygen sensor harness, or a poor electrical connection in the oxygen sensor circuit. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damage or signs of corrosion, and check for broken, bent, pushed out, or corroded pins on the connectors.

How can I visually inspect the wiring harness and connectors to fix the P118A fault code?

If you’re dealing with the P118A fault code and your engine light is on, it’s time to take action. The cause could be exhaust leaks, a faulty oxygen sensor, an open or shorted oxygen sensor harness, or a poor electrical connection in the oxygen sensor circuit. To fix this 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 delay, get to the bottom of this problem and ensure your engine is running smoothly.

What should I look for when checking for damaged components and connector’s pins to resolve the P118A fault code?

When resolving the P118A fault code, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. By doing so, you can identify any issues that may be causing the fault code. Remember to also consider other possible causes such as exhaust leaks, a faulty oxygen sensor, or a poor electrical connection in the oxygen sensor circuit.

p118a error fault code explained

If you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to a few reasons. It might be because of exhaust leaks, a faulty oxygen sensor, an open or shorted oxygen sensor harness, or a poor electrical connection in the oxygen sensor circuit.

To fix this, visually inspect the wiring harness and connectors, check for damaged components, and look for any broken, bent, pushed out, or corroded connector pins.
