P0060 — Heated Oxygen Sensor (HO2S) Bank 2 Sensor 2 – Heater Resistance #

Note: The description for DTC P0060 may vary by vehicle manufacturer (OEM). Always refer to the official factory documentation for your specific vehicle model.

• Heated Oxygen Sensor (HO2S) Heater Resistance (Bank 2, Sensor 2) — General (Generic OBD-II)
• O2 Sensor Heater Control Circuit (Bank 2, Sensor 2) — Ford
• Rear Heated Oxygen Sensor Heater Circuit Malfunction (Bank 2) — Toyota
• Downstream O2 Sensor 2 Heater Circuit Resistance (Bank 2) — GM

Summary of DTC P0060 #

P0060 is a generic OBD-II diagnostic trouble code that indicates the engine control module (ECM) has detected an abnormal resistance in the heater circuit of the heated oxygen sensor (HO2S) located at Bank 2, Sensor 2. Here, Bank 2 refers to the cylinder bank not containing cylinder 1, and Sensor 2 is the downstream (post-catalytic converter) oxygen sensor. The heater circuit is designed to quickly bring the sensor up to operating temperature for accurate fuel mixture readings. If resistance is too high or too low, sensor operation is compromised, potentially affecting emissions and engine performance. This code is flagged when the ECM detects a resistance value out of the expected range as specified by the OEM.

Common Symptoms for Code P0060 #

A vehicle with a P0060 code may continue to run, but certain driveability and emission-related symptoms can appear. Some symptoms might be subtle, while others can be more pronounced depending on the severity and duration of the issue.

• Check Engine Light (MIL) illuminated
• Poor fuel economy
• Failed emissions test
• Rough idle or hesitation (less common)
• Increased exhaust emissions
• Possible minor performance drop

Probable Causes for Code P0060 #

The most frequent causes for a P0060 code involve issues with the heater circuit of the oxygen sensor, but the fault may also be elsewhere in the wiring or the engine control module itself. Below are the most common causes, ranked by likelihood:

1. Faulty heated oxygen sensor (HO2S) at Bank 2, Sensor 2
2. Damaged or corroded wiring/connectors in the sensor heater circuit
3. Open or shorted heater circuit (broken wires or internal sensor fault)
4. Blown fuse or relay related to the O2 sensor heater
5. Faulty ECM (rare, but possible)

Step-by-Step Diagnosis for P0060 #

Diagnosing P0060 requires a systematic approach to avoid unnecessary part replacement. Here’s how a professional technician would typically proceed:

• Verify the code using a scan tool and check for related codes (especially other O2 sensor or heater circuit codes).
• Inspect the wiring and connectors at the Bank 2, Sensor 2 location for signs of damage, corrosion, or disconnection.
• Check the sensor heater circuit’s resistance with a multimeter; compare the value to OEM specifications (usually between 3–15 ohms when cold).
• Test for power and ground at the sensor connector with the ignition ON.
• Inspect the fuse and relay (if applicable) for the O2 sensor heater circuit.
• Backprobe the ECM connector (if necessary) to verify continuity in the heater circuit wiring.
• Replace the sensor if resistance is not within specification or if wiring/connector issues are ruled out.

Possible Repairs for P0060 #

Once the root cause is identified, repairs for P0060 tend to focus on restoring proper heater circuit function. Here are the most common fixes:

• Replace the Bank 2, Sensor 2 heated oxygen sensor (HO2S)
• Repair or replace damaged wiring or connectors in the sensor heater circuit
• Replace a blown fuse or faulty relay related to the O2 sensor heater
• Repair open or shorted heater circuit wiring
• Replace ECM (only if all other causes are ruled out and verified by advanced diagnostics)

Is It Safe to Drive with Code P0060? #

Limited. While P0060 usually does not cause immediate drivability issues, it can lead to increased emissions and may result in a failed emissions inspection. Prolonged driving with this code can cause the catalytic converter to work harder, potentially shortening its lifespan. If you notice additional symptoms such as rough running or poor fuel economy, address the issue promptly. For most vehicles, short-term driving is generally safe, but plan repairs soon.

Vehicles Most Commonly Affected by P0060 #

P0060 is a generic code, but it tends to appear more frequently on certain makes and models, especially as vehicles age. Models with known O2 sensor wiring vulnerabilities or high-mileage engines may be more susceptible.

• Chevrolet/GMC V6 and V8 engines (Silverado, Sierra, Trailblazer, etc.)
• Toyota V6 and V8 engines (Camry, Tacoma, Tundra, etc.)
• Ford F-series and SUVs (Expedition, Explorer)
• Nissan V6 engines (Pathfinder, Maxima)
• Hyundai/Kia V6 engines

Common Mistakes & Best Practices with P0060 #

Misdiagnosis of P0060 often leads to unnecessary sensor replacement or overlooking simple wiring faults. Follow these best practices to avoid wasted time and expense:

• Do not replace the O2 sensor without first inspecting wiring and connectors—external faults are more common than internal sensor failures.
• Avoid clearing the code before completing all diagnostic steps; intermittent wiring issues may reappear.
• Always use OEM or high-quality replacement sensors to ensure compatibility and longevity.
• Document the resistance measurement and repair steps for future reference.

Express FAQ for P0060 #

Q: Will replacing the sensor always fix P0060?
A: Not always. If the wiring, fuse, or relay is at fault, replacing the sensor alone won’t resolve the code. Always diagnose the circuit first.

Q: Can this code cause permanent engine damage?
A: Unlikely in the short term. However, extended operation with a non-functioning downstream O2 sensor can stress the catalytic converter and cause other emission failures.
