P0060 OBD-II Trouble Code: HO2S Heater Resistance (Bank 2 Sensor 2)

P0060 trouble code definition

P0060 indicates that there is an abnormal (usually high) resistance detected in the heater of the oxygen sensor, located after the catalytic convertor

What the P0060 code means

P0060 indicates that there is a malfunction in the oxygen sensor located after the catalytic convertor. The oxygen sensor is used to regulate the performance of the engine, such as fuel consumption. However the O2 sensor can only accurately regulate the engine performance after the sensor has reached a hot temperature. An engine will usually take about 15 minutes of running to heat the oxygen sensor up to its required hot temperature.

An accurate oxygen sensor reading is needed immediately after the engine is running. The internal heaters were built into the sensors to warm them up faster than the engine can alone. The computer of the vehicle will “know” the temperature of the oxygen sensor by monitoring the resistance of the oxygen sensor. If the resistance is out of range the computer will assume that the temperature of the oxygen sensor is unsatisfactory.

What causes the P0060 code?

• Worn heater element in the oxygen sensor

• Corrosion in the connections or electrical terminals

• Shorted wiring of the oxygen sensor

What are the symptoms of the P0060 code?

• Increased fuel consumption

• Engine misfiring at idle

• Check Engine Light illuminating

• Engine runs poorly until it reaches operating temperature

How does a mechanic diagnose the P0060 code?

• Removing the oxygen sensor from the exhaust but leaving the wiring connected to determine if the Sensor is heating on its own

• Examining the connections and wiring related to the oxygen sensor

• Measuring the resistance of the oxygen sensor and comparing it to manufacturers specifications

Common mistakes when diagnosing the P0060 code

• Replacing the sensor without evaluating the wiring and electrical connections related to the sensor

• Improperly distinguishing sensor 1 from sensor 2 and replacing the wrong sensor

How serious is the P0060 code?

The emissions system of the vehicle will monitor the emissions output through the readings of the oxygen sensor. The computer of the vehicle will make adjustments to the emissions output according to the oxygen sensor’s readings.

If the oxygen sensor is malfunctioning the vehicle will usually emit higher amounts of emissions which is worse for the environment. Also an increased emissions output will shorten the lifespan of the catalytic convertor.

What repairs can fix the P0060 code?

Usually a replacement of bank 2 oxygen sensor 2 will fix this particular code.

Additional comments for consideration regarding the P0060 code

Please ensure all of the oxygen sensor related connections and wiring are undamaged and in working order.
