O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 2)
The P0060 code indicates a problem with the heater circuit in the oxygen sensor located after the catalytic converter on Bank 2 (the side opposite cylinder #1). The Engine Control Module (ECM) monitors the current draw of the heater element; if it detects resistance outside the expected range, it sets this code. This can lead to inaccurate sensor readings, affecting fuel trim and emissions.
01. 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
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Failed emissions test
- Possible slight decrease in fuel economy
- No noticeable drivability issues in most cases
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the O2 sensor connector and wiring for damage, corrosion, or loose connections.
Step 3: Using a multimeter, measure the resistance of the heater element between the two heater wires (typically white wires). Compare to manufacturer specs (usually 2-10 ohms).
Step 4: Check for battery voltage at the heater circuit with the key on. If no voltage, check fuses and relay.
Step 5: If voltage and ground are present but resistance is out of spec, replace the oxygen sensor.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
Yes, it is generally safe to drive short distances, but the Check Engine Light will remain on. Prolonged driving may cause increased emissions and potential catalytic converter damage if the sensor fails completely.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for a DIY replacement of the oxygen sensor. Professional repair may cost $150-$300 including parts and labor.
