P0060 is an OBD-II generic code that indicates a problem with the HO2S (Heated Oxygen Sensor) heater circuit for Bank 2, Sensor 2. This refers to the downstream oxygen sensor on the second bank of cylinders in the engine.

The purpose of the HO2S heater circuit is to ensure that the oxygen sensor reaches its operating temperature quickly. This allows for more accurate readings and better fuel control. When the heater circuit malfunctions, the sensor may not heat up properly or at all, leading to inaccurate readings and potentially causing issues with engine performance and emissions.

The most common cause of the P0060 code is a faulty oxygen sensor heater element. This could be due to a short circuit in the heater circuit or a problem with the sensor itself. However, other possible causes may include issues with the wiring or connectors in the heater circuit, a blown fuse, or a problem with the engine control module (ECM).

To diagnose and repair the P0060 code, a mechanic will typically perform the following steps:

1. Use an OBD-II scanner to check for any additional fault codes and to ensure that the P0060 code is accurate.
2. Inspect the wiring and connectors of the HO2S heater circuit for any damage, loose connections, or corrosion. Repair or replace as necessary.
3. Test the oxygen sensor heater element for resistance using a multimeter. If the resistance value is out of the specified range, the sensor will need to be replaced.
4. If the wiring and sensor check out, test the ECM to ensure it is sending the proper voltage to the sensor.
5. Clear the fault codes and test drive the vehicle to see if the code returns. If it does not return, the issue has likely been resolved.

It is important to address the P0060 code promptly as it can affect fuel efficiency, emissions, and overall engine performance. If you are not experienced with automotive diagnostics and repairs, it is recommended to have the issue diagnosed and repaired by a qualified mechanic.

What are the symptoms of the P0060 code?

The P0060 fault code refers to a problem with the HO2S (Heated Oxygen Sensor) heater resistance on Bank 2, Sensor 2. This code usually indicates a malfunction in the electrical circuit or resistance of the oxygen sensor.

Symptoms of P0060 may include:

• Check Engine Light (CEL) illumination
• Decreased fuel efficiency
• Rough idling or engine misfires
• Hesitation or lack of power during acceleration
• Failed emissions test

It is recommended to have the issue diagnosed and repaired by a qualified mechanic to ensure proper functioning of the oxygen sensor and the vehicle's emission control system.

What causes the P0060 code?

The P0060 fault code refers to the HO2S (Heated Oxygen Sensor) Heater Resistance for Bank 2, Sensor 2. This code indicates a problem with the heater circuit of the oxygen sensor located in the second bank of cylinders, typically on the downstream side of the catalytic converter.

There are several possible causes for this fault code, including:

1. Faulty oxygen sensor: The oxygen sensor itself may be malfunctioning and not heating up properly.
2. Open or short in the sensor wiring: There may be a break or short circuit in the wiring harness connecting the sensor to the vehicle's electrical system.
3. Faulty sensor heater relay: The relay that controls the power supply to the sensor's heater circuit may be faulty, leading to insufficient heating.
4. Defective PCM (Powertrain Control Module): The vehicle's main computer that controls engine functions may be malfunctioning and not providing the necessary voltage to the sensor.

To diagnose the exact cause of the P0060 fault code, it is recommended to use a diagnostic scan tool to retrieve any additional codes and data from the vehicle's computer system. A thorough inspection of the sensor and its wiring should be performed to check for any visible signs of damage or corrosion. Additionally, electrical tests should be carried out to determine if the sensor is receiving the proper voltage and if there are any faults in the wiring or relay.

Once the cause of the fault code is determined, the necessary repairs or replacements can be made to rectify the issue. It is important to address this fault code promptly, as a malfunctioning oxygen sensor can negatively affect fuel efficiency and emissions performance.

How to fix P0060?

To fix the P0060 fault code, which indicates a HO2S (Heated Oxygen Sensor) Heater Resistance problem for Bank 2, Sensor 2, you can follow these steps:

1. Inspect the electrical connections: Check the wiring harness and connectors associated with the Bank 2, Sensor 2 oxygen sensor. Look for any damaged or loose connections that could cause a resistance issue. Repair or replace any faulty wiring or connectors as necessary.

2. Test the oxygen sensor: Use a multimeter or an OBD-II scanner that can monitor live data to test the Bank 2, Sensor 2 oxygen sensor. Monitor the sensor's voltage and resistance readings, comparing them to manufacturer specifications. Replace the oxygen sensor if it is not functioning within the specified range.

3. Check the oxygen sensor fuse: Locate and inspect the fuse for the oxygen sensor heater circuit. If the fuse is blown, replace it and retest the system. If the fuse continues to blow, there may be an underlying wiring issue that needs further inspection.

4. Inspect the ECM/PCM: The Engine Control Module/Powertrain Control Module (ECM/PCM) controls the oxygen sensor heater circuit. Inspect the ECM/PCM connectors for any signs of damage, corrosion, or loose pins. Repair or replace the ECM/PCM as necessary.

5. Clear the fault code: Once you have completed the necessary repairs or replacements, clear the fault code using an OBD-II scanner or by disconnecting the battery for a few minutes. After clearing the code, test the vehicle to ensure the P0060 code does not reappear.

Note: It is recommended to consult the vehicle's service manual or seek professional assistance if you are unfamiliar with these procedures or if the fault code persists after attempted repairs.
