O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 2)
The P0060 code indicates a problem with the heater circuit resistance in the oxygen sensor located on Bank 2, Sensor 2 (downstream of the catalytic converter). The engine control module (ECM) monitors the heater's current draw; when resistance is out of spec, it sets this code. This can affect the sensor's ability to reach operating temperature quickly, leading to inaccurate readings and potential emissions issues.
1. Most Common Causes
- Faulty oxygen sensor (Bank 2, Sensor 2)
- Open or shorted heater circuit wiring
- Blown fuse for O2 sensor heater
- Corroded or damaged connector
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Failed emissions test
- Possible poor fuel economy
- Rough idle or hesitation (rare)
3. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P0060 is present.
Step 2: Visually inspect the O2 sensor connector and wiring for damage or corrosion.
Step 3: Measure heater resistance at the sensor connector (typically 2-10 ohms).
Step 4: Check for battery voltage and ground at the heater circuit with key on.
Step 5: If voltage and ground are present but resistance is out of spec, replace the sensor.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
Yes, but the vehicle may fail an emissions test and fuel economy could suffer. It's best to repair promptly.
How much does it cost to fix?▼
Typically $50-$150 for a DIY replacement of the oxygen sensor; labor adds $50-$100 if done by a shop.
5. Commonly Affected Makes
This is a generic OBD2 code, potentially applicable to any manufacturer using this diagnostic standard.
