P0060
UniversalHO2S Heater Resistance (Bank 2, Sensor 2)
Medium SeverityThis code indicates that the resistance in the heater circuit of the Heated Oxygen Sensor (HO2S) on Bank 2, Sensor 2 is outside of specifications. This prevents the sensor from reaching its optimal operating temperature quickly, which can lead to inefficient fuel combustion and increased emissions.
⚠️ Before You Begin (Safety First)
Always ensure the vehicle is safely supported on jack stands if working underneath. Disconnect the battery before performing any electrical work or replacing components to prevent electrical shock or damage to the vehicle's electrical system. Allow exhaust components to cool completely before touching them to avoid severe burns.
Common Symptoms
- Check Engine Light illuminated
- Decreased fuel economy
- Increased exhaust emissions (may fail emissions test)
- Engine running slightly rich or lean at startup
Common Causes
- Faulty oxygen sensor heater element (most common)
- Open or short circuit in the HO2S heater wiring
- Corroded or loose electrical connectors
- Faulty Powertrain Control Module (PCM) (less common)
Frequently reported on: General/Universal
Diagnostic Steps
- Connect an OBD-II scanner to confirm P0060 is the active code.
- Visually inspect the Bank 2 Sensor 2 HO2S and its wiring harness for any signs of damage, fraying, or corrosion.
- Using a multimeter, test the resistance of the heater circuit wires on the oxygen sensor connector. Compare the reading to the manufacturer's specifications (usually found in a service manual).
- If the resistance is out of specification, replace the faulty Bank 2 Sensor 2 oxygen sensor.
- Clear the DTCs (Diagnostic Trouble Codes) using the OBD-II scanner and perform a test drive to ensure the code does not return.
👨🔧 When to Call a Professional
While replacing an oxygen sensor can be a DIY task, if you lack experience with electrical diagnostics, specialized tools like a multimeter, or if the sensor is seized due to rust, it's best to consult a professional mechanic. They have the expertise to accurately diagnose wiring issues and ensure proper installation.
Commonly Asked Questions
What does P0060 specifically mean?
P0060 indicates an issue with the electrical resistance within the heater circuit of the downstream oxygen sensor on engine Bank 2. The heater helps the sensor reach operating temperature faster for accurate readings.
Can I drive my car with a P0060 code?
While you can typically drive with this code, it's not recommended for extended periods. It can lead to reduced fuel efficiency, increased emissions, and potentially cause the catalytic converter to degrade over time due to improper fuel mixture readings.
Where is Bank 2 Sensor 2 located?
Bank 2 is the side of the engine that does NOT contain cylinder #1. Sensor 2 is the downstream oxygen sensor, located after the catalytic converter on that side of the exhaust system.
How do I test the oxygen sensor heater circuit?
With the sensor unplugged, use a multimeter set to ohms to measure the resistance between the two heater wires on the sensor side (usually two wires of the same color, often white or black). Compare this reading to your vehicle's service manual specifications.
Do I need any special tools to replace an oxygen sensor?
An oxygen sensor socket or wrench is highly recommended, as standard wrenches often don't fit due to the wiring. A torque wrench is also useful for proper installation.
