P0060 HO2S Heater Resistance Bank 2 Sensor 2

P0060 indicates heater resistance outside expected limits for bank 2 sensor 2. The downstream bank 2 oxygen sensor heater circuit is abnormal.

Code details

Generic OBD-II · P0

System: Fuel / Air
Code type: Generic (SAE / ISO controlled)
Standard: SAE J2012 / ISO 15031-6

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace catalyst or downstream sensors before verifying heater resistance and circuit power at bank 2 sensor 2.

Symptoms of P0060

Check-engine light on, sometimes with rough or uneven running.
Hesitation, surging, or a noticeable change in fuel economy.
Occasionally hard starting or a smell of unburnt fuel.

Common causes of P0060

A failing or contaminated sensor (MAF, MAP, oxygen or air-fuel sensor).
Intake or vacuum leaks, or an exhaust leak near an upstream sensor.
Wiring, connector, or fuel-delivery problems that skew the reading.

Useful checks before replacing parts

Measure bank 2 sensor 2 heater resistance, feed voltage, ground or control command, current draw, and connector terminal tension.
Inspect downstream exhaust wiring, melted insulation, loose clips, sensor connector corrosion, fuse feed, and shared heater faults.
Compare heater operation with catalyst monitor readiness, downstream sensor activity, and stored freeze-frame temperature.
