[SOLVED] P1167 Code: Fixing Heated Rear Oxygen Sensor 2 Maximum Voltage

The automobile fault code P1167 indicates a problem with the AirFuel Ratio Sensor 1. This can cause the Engine Light to turn on or the Service Engine Soon Warning Light to illuminate.

The possible causes include a faulty sensor, an open or shorted harness, or a poor electrical connection in the sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors for any damage. Look out for broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this problem is estimated to be around 1.0 hour.

To interpret the fault code, check the “Possible Causes” mentioned above and perform the necessary inspections and repairs.

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1167 fault code.

  • The symptoms of the automobile fault code p1167 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1167 can be caused by a faulty AirFuel Ratio Sensor 1, an open or shorted harness, or a poor electrical connection in the sensor circuit.

  • The fault code P1167 can be caused by a faulty Air/Fuel Ratio Sensor 1, an open or shorted harness for the Air/Fuel Ratio Sensor 1, or a poor electrical connection in the Air/Fuel Ratio Sensor 1 circuit.

To fix the p1167 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p1167, 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 should take approximately 1.0 hour.

The factors influencing the diagnosis and fixing cost of automobile fault code p1167 are the estimated repair time of 1.0 hour and the average hourly rate charged by auto repair shops, which ranges between $75 and $150.

The P1167 fault code refers to the Heated Rear Oxygen Sensor 2 Maximum Voltage Monitoring Bank 2. This sensor is responsible for detecting the oxygen content in the exhaust gas.

It is installed in the exhaust system and transmits output voltage to the Engine Control Module (ECM).

The sensor has a built-in heater that is activated to stabilize and speed up the detection of oxygen content. The current amperage flowing through the heater is proportional to the oxygen content in the exhaust gas, allowing the ECM to determine the airfuel ratio. If the voltage from the sensor is low, it indicates a lean airfuel ratio, and the ECM will issue a Rich command to adjust the fuel injection timing.

On the other hand, if the voltage is high, it indicates a rich airfuel ratio, and the ECM will issue a Lean command.

The P1167 fault code specifically relates to the maximum voltage monitoring of the Heated Rear Oxygen Sensor 2 in Bank 2.

This code indicates that the voltage from the sensor has exceeded the maximum allowable limit, and further diagnosis and repair are required to address the issue.

What are the possible causes of the automobile fault code P1167?

If you see the engine light or service engine soon warning light on, the fault code P1167 could be the culprit. This code is often caused by a faulty air/fuel ratio sensor 1, 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 signs of damage or corrosion, and check if any components are broken or bent. Don’t forget to examine the connector’s pins for any signs of being pushed out or corroded.

How can I visually inspect the wiring harness and connectors to fix the P1167 fault code?

If you’re dealing with the P1167 fault code and your engine light is on, it’s time to take action. The culprit could be a faulty Air/Fuel Ratio Sensor 1 or issues with the sensor’s wiring harness and connectors. To fix this, 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 simple step could be the key to resolving the issue and getting your engine running smoothly again.

What should I look for when checking for damaged components and connector pins to resolve the P1167 fault code?

When resolving the P1167 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 Air/Fuel Ratio Sensor 1 or its circuit connection. By thoroughly examining these areas, you can pinpoint the cause of the fault code and take appropriate action to fix it.
