P0060 HO2S Heater Resistance (Bank 2 Sensor 2)

The OBD2 code P0060 indicates a problem with the heater resistance of the oxygen sensor located in Bank 2, Sensor 2, which may affect the sensor's ability to heat up properly for accurate readings

Definition

The OBD2 code P0060 indicates a problem with the heater resistance of the oxygen sensor located in Bank 2, Sensor 2, which may affect the sensor's ability to heat up properly for accurate readings

Common causes

  • Faulty oxygen sensor (Bank 2, Sensor 2)
  • Open or shorted wiring in the heater circuit
  • Poor electrical connections or corroded connectors
  • Blown fuse related to the oxygen sensor heater circuit
  • Faulty engine control module (ECM) or powertrain control module (PCM)
  • Exhaust leaks near the sensor
  • Incorrect sensor installation or aftermarket sensor issues

Common misdiagnoses

  • Faulty oxygen sensor
  • Wiring issues or shorts in the sensor circuit
  • Engine control module (ECM) failure
  • Exhaust leaks
  • Fuel system problems
  • Air intake issues
  • Incorrectly installed or damaged sensor
  • Other sensor failures (e.g., MAF or MAP sensors)

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other trouble codes that may be present. This can help identify if there are related issues that need to be addressed

  2. 2. Inspect the Oxygen Sensor

    Visual Inspection: Check the wiring and connector for the Bank 2, Sensor 2 oxygen sensor. Look for signs of damage, corrosion, or loose connections

  3. 3. Sensor Condition

    Inspect the sensor itself for any signs of contamination or physical damage

  4. 4. Test the Oxygen Sensor

    Resistance Test: Disconnect the sensor and use a multimeter to measure the resistance of the heater element. Compare the reading to the specifications provided by the manufacturer. If the resistance is out of range, the sensor may need to be replaced

  5. 5. Voltage Test

    With the engine running, check the voltage at the sensor connector to ensure that the heater circuit is receiving the correct voltage (usually around 12V)

  6. 6. Check the Heater Circuit

    Wiring Inspection: Inspect the wiring harness for any breaks, shorts, or corrosion that could affect the heater circuit

  7. 7. Fuse Check

    Check the fuse related to the oxygen sensor heater circuit. If the fuse is blown, replace it and see if the code returns

  8. 8. Test the Engine Control Module (ECM)

    Ensure that the ECM is functioning properly. If the ECM is not sending the correct signals to the oxygen sensor heater, it may need to be reprogrammed or replaced

  9. 9. Check for Exhaust Leaks

    Inspect the exhaust system for any leaks that could affect the readings of the oxygen sensor. Exhaust leaks can lead to incorrect sensor readings and may trigger codes

  10. 10. Clear the Codes and Test Drive

    After performing the necessary repairs or replacements, clear the trouble codes using the OBD-II scanner. Take the vehicle for a test drive to see if the code returns

  11. 11. Consult Repair Manual

    If the issue persists, consult the vehicle’s repair manual for specific diagnostic procedures and specifications related to the oxygen sensor and its circuit

  12. 12. Professional Diagnosis

    If you are unable to resolve the issue after following these steps, consider seeking help from a professional mechanic who can perform more advanced diagnostics. By following these troubleshooting steps, you should be able to identify and resolve the issue related to the P0060 code
