P0060 – HO2S Heater Resistance (Bank 2, Sensor 2) (OBD2)

P0060 means "HO2S Heater Resistance (Bank 2, Sensor 2)". The oxygen sensor heater brings the sensor up to its working temperature quickly after a cold start, so fuel control and catalytic converter monitoring can start early.

Why oxygen sensors have heaters

An oxygen sensor only works properly at several hundred degrees Celsius. Exhaust gas alone takes too long to heat it, so every modern sensor has an electric heating element. The heater usually gets battery voltage through a fuse or relay, and the engine control unit switches the ground side on and off to control the temperature.

The control unit monitors the heater current and resistance. If the circuit is open, shorted or the resistance is outside the expected window, it stores a heater code for that specific sensor (bank and sensor number). Until the sensor is hot enough, fuel control stays in open loop, which increases emissions and fuel consumption.

Heater faults are among the most common oxygen sensor problems. Because the heater is built into the sensor, a failed heater element normally means replacing the whole sensor – but blown fuses and wiring damage near the exhaust are common too and much cheaper to fix.

Bank 2 is the cylinder row that does NOT contain cylinder 1, so this code only appears on V6, V8, V10, V12 and boxer engines.

Sensor 2 is the downstream oxygen sensor, mounted after the catalytic converter. It mainly monitors how well the catalytic converter works.

On VAG vehicles (VW, Audi, Škoda, Seat, Cupra), VCDS and older VAG testers can show this code as the five-digit VAG code 16444 (P0060). Both numbers mean the same fault.

Symptoms of P0060

  • Check Engine light on
  • Slightly higher fuel consumption, especially on short trips
  • Rough running in the first minutes after a cold start
  • Failed emissions test
  • Often no noticeable driving symptoms

Mechanic's Pro Tip

Measure the heater resistance before buying a sensor. If it reads correctly, the problem is in the fuse, supply or wiring – often a melted cable touching the exhaust. That simple measurement saves the price of an unnecessary sensor.

  1. 1.Burnt-out heater element in the oxygen sensor

    Most likely

    The most common cause – the sensor must be replaced.

  2. 2.Blown fuse or faulty relay for the heater supply

    If several sensors report heater faults at once, check the shared fuse first.

  3. 3.Wiring damaged by heat or chafing

    The sensor cable often runs close to the exhaust.

  4. 4.Corroded or loose connector

    Underbody connectors are exposed to water and road salt.

  5. 5.Fault in the control unit's heater driver

    Rare; usually after a shorted heater or wiring damaged the driver.

Step-by-step diagnostic guide

  1. 1

    Read codes

    Read all codes and note which bank and sensor are affected. Several heater codes at once usually point to a shared fuse or supply.

  2. 2

    Check the fuse and supply voltage

    With the ignition on, check for battery voltage on the heater supply wire at the sensor connector.

  3. 3

    Measure the heater resistance

    Unplug the sensor and measure across the two heater terminals (usually the two wires of the same colour).

    Multimeter: Typical heater resistance: about 2–15 Ω at room temperature depending on the sensor. 'OL' means the heater is burnt out.

  4. 4

    Check the ground (control) wire

    Check the control wire from the sensor to the engine control unit for continuity and shorts to ground or voltage.

  5. 5

    Replace and clear

    Replace the sensor if the heater is open or shorted, repair wiring if damaged, then clear codes and confirm the heater test passes after a cold start.

Frequently asked questions

Can I keep driving with P0060?

Yes. The engine runs normally once the exhaust has warmed the sensor, but emissions and fuel consumption are higher after cold starts and the car may fail an emissions test.

How much does it cost to fix P0060?

Typical repair costs are 5 € – 300 €, depending on the cause and the vehicle. The most common fixes are: burnt-out heater element in the oxygen sensor; blown fuse or faulty relay for the heater supply; wiring damaged by heat or chafing. Always confirm the cause with the tests above before buying parts.

Is an oxygen sensor heater code serious?

Not urgent for the engine, but fuel control starts later after each cold start, so emissions and consumption rise. It should be fixed before the next emissions test.

Can I replace only the heater?

No. The heater element is built into the sensor, so a failed heater means replacing the oxygen sensor.

What is the difference between P0060 and similar codes?

P0060 belongs to a group of codes for the same component that differ in the type or location of the fault: P0057 – Heated Oxygen Sensor (HO2S) Heater Circuit Low Voltage Bank 2 Sensor 2; P0058 – Heated Oxygen Sensor (HO2S) Heater Circuit High Voltage Bank 2 Sensor 2; P0059 – HO2S Heater Resistance (Bank 2, Sensor 1); P0061 – HO2S Heater Resistance (Bank 2, Sensor 3); P0062 – HO2S Heater Control Circuit (Bank 2, Sensor 3); P0063 – HO2S Heater Control Circuit Low (Bank 2, Sensor 3). The tests on this page apply to the whole group; the type of fault tells you where to start.
