P0060 medium Severity

P0060: HO2S Heater Resistance (Bank 2, Sensor 2) – abnormal resistance detected in the heated oxygen sensor heater circuit on engine Bank 2 Sensor 2

Check Engine Light illuminated; potential reduced fuel efficiency and emissions performance; minor drivability symptoms possible

Overview

OBD-II DTC P0060 indicates abnormal resistance in the heated downstream oxygen sensor heater circuit (Bank 2, Sensor 2), often due to heater element failure or wiring issues affecting emissions and sensor operation

Common Symptoms

  • Check Engine Light (MIL) illuminated
  • Decreased fuel efficiency
  • Rough idle or hesitation
  • Poor emissions test results
  • Possible minor performance degradation

Most Common Causes

Faulty heated oxygen sensor (Bank 2, Sensor 2) high

Heater element internal failure or abnormal resistance triggers the code

Damaged, corroded, or disconnected wiring/connectors in heater circuit high

Open or shorted heater circuit wiring commonly reported

Blown fuse or faulty relay to heater circuit medium

Power supply interruption to heater circuit can mimic sensor fault

Faulty PCM/ECM heater driver output low

Rare; consider only after wiring and sensor tests are complete

Diagnostic Steps

  1. Connect OBD-II scanner and confirm presence of P0060; check for related codes
    Expected: P0060 code stored
    Interpretation: Confirms issue with Bank 2 Sensor 2 heater circuit
  2. Visually inspect wiring and connectors at Bank 2 Sensor 2 for damage or corrosion
    Expected: No broken, corroded, or loose connections
    Interpretation: If issues found, repair may clear code
  3. Measure heater circuit resistance with multimeter
    Expected: Resistance within manufacturer specification (typically low ohms)
    Interpretation: Out-of-range resistance suggests sensor heater fault
  4. Check power and ground at sensor connector with ignition ON
    Expected: Proper voltage and ground present
    Interpretation: No power/ground suggests wiring or fuse/relay issue

Repair Solutions

Replace heated oxygen sensor (Bank 2, Sensor 2) medium
Estimated Cost: $150 - $500

Most common repair when heater resistance out of spec

Repair or replace damaged wiring/connectors in heater circuit medium
Estimated Cost: $50 - $200

Effective when visual damage is detected

Replace blown fuse or faulty relay supplying heater circuit easy
Estimated Cost: $5 - $50

Simple fix if power supply interruption is root cause

ECM/PCM repair or replacement hard
Estimated Cost: $800 - $1200

Only if controller is confirmed faulty after all other causes ruled out

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Interpreting P0060 as general oxygen sensor failure rather than heater circuit issue

Frequently Asked Questions

Can you explain the meaning of P0060?

When your OBD-II scanner reads P0060, it means: HO2S Heater Resistance (Bank 2, Sensor 2) – abnormal resistance detected in the heated oxygen sensor heater circuit on engine Bank 2 Sensor 2. This code is related to the vehicle's Sensors.

Should I stop driving if I have P0060?

You should treat P0060 as a medium issue. Check Engine Light illuminated; potential reduced fuel efficiency and emissions performance; minor drivability symptoms possible

Symptoms associated with DTC P0060

Drivers often report: Check Engine Light (MIL) illuminated, Decreased fuel efficiency, Rough idle or hesitation when this code is present.

Common triggers for the P0060 error

Potential culprits include: Faulty heated oxygen sensor (Bank 2, Sensor 2), Damaged, corroded, or disconnected wiring/connectors in heater circuit, Blown fuse or faulty relay to heater circuit. A proper diagnosis is recommended.

How much does it cost to fix P0060?

The cost varies significantly based on the root cause. For example, replacing a Replace blown fuse or faulty relay supplying heater circuit typically costs between $5 and $50, while fixing a ECM/PCM repair or replacement can range from $800 to $1200.

Is the P0060 code specific to Mercedes?

P0060 is not specific to any one brand. It can appear on Ford, Dodge, Toyota, Honda, Jeep, and other vehicles.
