Oxygen (O2) sensors are crucial for engine operation and performance. They monitor the amount of oxygen in the exhaust and send data to your vehicle’s powertrain control module (PCM). The PCM uses the signal from the upstream sensor in determining the amount of fuel to inject into the engine. Meanwhile, the module primarily uses the signal from the downstream sensor to determine the efficiency of the catalytic converter.
Just like any other engine sensors, it isn’t uncommon for oxygen sensors to malfunction at one point. Thankfully, modern vehicles are equipped with on-board diagnostic (OBD) systems to help you or a mechanic identify a potential fault in your vehicle, including malfunctioning oxygen sensors.
P0060 is just one of the several diagnostic trouble codes (DTC) related to a potential issue with the operation of the oxygen sensor’s heater circuit. If your scan tool read this code and you’re wondering what it means, read up to learn more.
What Does the P0060 Code Mean?
Diagnostic Trouble Code (DTC) P0060 stands for “HO2S Heater Resistance Bank 2 Sensor 2.” It’s logged once the PCM detects a potential fault in the heater circuit of the downstream oxygen sensor (Sensor 2) that’s located in Bank 2. Bank 2 refers to the side of the engine that doesn’t contain cylinder #1.
This trouble code is specifically logged once the PCM detects that the resistance level in the oxygen sensor heater circuit is higher than the manufacturer-specified range.
An oxygen sensor needs to be kept at a certain temperature to send accurate information to the PCM. These sensors usually have a heated wire to help them achieve a heated state. A conventional oxygen sensor will only send a signal to the PCM once its tip reaches a certain temperature.
Once your PCM detects a level of resistance in your oxygen sensor heater circuit that is higher than the specified range, it will trigger this error code. In certain vehicle models, it will take multiple ignition cycles before the check engine light will illuminate.
Note: The definition of code P0060 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
What are the Possible Causes of the P0060 Code?
Here are some common triggers of the code:
- Damaged wiring and/or connectors
- Faulty oxygen sensor
- Blown fuse
- Burn fusible link
- Malfunctioning relay
- An issue with the PCM
What are the Common Symptoms of the P0060 Code?
Below are some symptoms related to this error code:
- Illuminated check engine light
- Decreased fuel efficiency
How to Diagnose a P0060 Code
It isn’t easy to diagnose any OBD-II code, including code P0060. If you’re not an experienced DIYer, it is best to take your vehicle to an auto repair shop and have your vehicle checked by a mechanic.
However, if you want to try to diagnose this code yourself, we suggest consulting a repair manual or an online repair database. These resources will help you identify the diagnostic steps compatible with your vehicle’s year, make, and model.

How to Fix a P0060 Code
While the symptoms and causes of code P0060 may be similar in some makes and models, the repair and diagnostic steps for each vehicle may vary. For example, information for fixing a code P0060 on a Ford F-150 may prove different from a guide for a code P0060 on a Chevy Tahoe.
You may choose to do the necessary repairs yourself or decide to hire a mechanic to do it for you. If you choose the former, make sure to get a vehicle-specific repair manual to learn about the appropriate factory repair procedures.
