What Does P0060 Mean?
The ECM has detected that the heater element resistance in the heated oxygen sensor (HO2S) at Bank 2, Sensor 2 (downstream of catalytic converter) is outside the expected range. This heater brings the O2 sensor to operating temperature quickly after startup for accurate emissions monitoring. The driver may notice increased cold-start emissions, slightly higher fuel consumption during warmup, and the check engine light.
Common Causes
40%
Degraded or failed O2 sensor heater element (internal resistance drift)
25%
Corroded or high-resistance connector at the O2 sensor
18%
Damaged wiring between ECM and O2 sensor heater circuit
10%
Poor ground connection for the O2 sensor heater
7%
ECM heater control driver circuit degradation
Diagnostic Steps
1
Measure the heater element resistance at the O2 sensor connector (sensor disconnected). Typical range is 2-15 ohms at room temperature, depending on manufacturer. Compare to factory specification.
2
Check for voltage at the O2 sensor heater power supply wire — should be battery voltage (12V+) with key on. Low voltage indicates a wiring or fuse issue.
3
Inspect the O2 sensor connector for corrosion, moisture intrusion, or melted pins caused by exhaust heat. The Bank 2 Sensor 2 position (downstream) is particularly exposed to road spray and heat.
4
Measure the resistance of the heater supply and ground wires from the ECM connector to the O2 sensor connector. Each wire should be less than 1 ohm. High resistance in the wiring adds to the measured heater resistance.
5
If heater resistance is out of spec, replace the O2 sensor. Apply anti-seize to threads and use a torque wrench to tighten to 30-45 Nm (manufacturer-specific).

The most common cause of P0060 (HO2S Heater Resistance (Bank 2, Sensor 2)) is: Degraded or failed O2 sensor heater element (internal resistance drift)
Typical repair costs for P0060 range from $100 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to continue driving. The O2 sensor will still function once it reaches operating temperature from exhaust heat alone, but it will take longer. Cold-start emissions will be elevated. This is primarily an emissions concern and will cause a failed emissions test. Repair at your convenience within a month.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0060 to identify the root cause.
