To fix the p1163 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1163, 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 p1163 are the estimated repair time of 1.0 hour and the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

The P1163 fault code refers to the Heated Oxygen Sensor 1 Lean Shift Monitoring Bank 2.

This sensor is located in the front tube of the exhaust system and is responsible for detecting the amount of oxygen in the exhaust gas compared to the outside air.

The Heated Oxygen Sensor 1 is equipped with a closed-end tube made of ceramic zirconia.

This zirconia generates voltage ranging from approximately 1V in richer conditions to 0V in leaner conditions. The sensor sends its signal to the Engine Control Module (ECM), which then adjusts the injection pulse duration to achieve the ideal air-fuel ratio.

The ideal air-fuel ratio is achieved when there is a radical change in voltage from 1V to 0V. The P1163 fault code indicates that the ECM has detected a lean shift in the Heated Oxygen Sensor 1 in Bank 2.

This means that the sensor is reporting a lean air-fuel mixture, which may require further investigation and potential repairs to ensure optimal engine performance.

What are the possible causes of the automobile fault code p1163?

If you see the engine light on or the service engine soon warning light, the fault code P1163 could be the culprit. This code is often caused by a faulty front heated oxygen sensor in bank 2, a faulty front heated oxygen sensor 1 heater, fuel pressure issues, faulty fuel injectors, or intake air leaks. To fix the problem, start by checking the possible causes mentioned above. Take a close look at the wiring harness and connectors, inspect for any damage, and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the fault code p1163?

If you’re dealing with the fault code p1163 and your engine light is on, it’s time to take action. The possible causes include a faulty front heated oxygen sensor, fuel pressure issues, faulty fuel injectors, or intake air leaks. To fix the problem, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This step is crucial in identifying any issues that may be causing the fault code.

What should I look for when checking for damaged components and corroded connector’s pins to resolve the fault code p1163?

When troubleshooting the fault code p1163, start by checking for damaged components and corroded connector’s 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 pins. By addressing these issues, you can resolve the problem and turn off the Engine Light or Service Engine Soon Warning Light. Don’t forget to also consider other possible causes such as a faulty front heated oxygen sensor, fuel pressure, faulty fuel injectors, or intake air leaks.

p1163 error fault code explained

If your engine light is on and you’re seeing the P1163 fault code, it could be due to a faulty front heated oxygen sensor bank 2, a faulty front heated oxygen sensor 1 heater, fuel pressure issues, faulty fuel injectors, or intake air leaks.

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.
