P0062 severity depends on the specific fault. While some causes are minor (e.g., sensor failure), others can affect performance or emissions. Diagnosis is recommended.

Can I drive with P0062?

Short trips may be possible, but prolonged driving with P0062 active is not advised until the root cause is identified and repaired.

Will P0062 clear itself?

P0062 may clear if the fault is intermittent, but it will likely return if the underlying issue is not resolved. Use a scanner to monitor pending and confirmed codes.

P0062 - HO2S Heater Control Circuit (Bank 2 Sensor 3)

P0062 is a Diagnostic Trouble Code (DTC) indicating a fault related to HO2S Heater (Bank 2 Sensor 3). This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles. When P0062 is stored in the engine control module (ECM), it means the onboard diagnostics have detected a malfunction or out-of-range condition in the HO2S Heater (Bank 2 Sensor 3) circuit or system.

What is P0062?

P0062 is a Diagnostic Trouble Code (DTC) indicating a fault related to HO2S Heater (Bank 2 Sensor 3). This code falls within the Powertrain (P) category and is standardized across OBD2-equipped vehicles.

When P0062 is stored in the engine control module (ECM), it means the onboard diagnostics have detected a malfunction or out-of-range condition in the HO2S Heater (Bank 2 Sensor 3) circuit or system.

Common Symptoms

Poor fuel economy
Rough idle
Failed emissions test
Engine hesitation during acceleration

Possible Causes

Failed oxygen sensor
Wiring or connector damage
Exhaust leak affecting readings
Engine running rich or lean

Step-by-Step Diagnosis

Connect an OBD2 scanner and confirm the code is present. Note any additional codes.
Review freeze frame data to understand engine conditions when the code was set.
Visually inspect the HO2S Heater (Bank 2 Sensor 3) and related wiring harness for damage, corrosion, or loose connections.
Perform a wiggle test on wiring while monitoring live data (if applicable).
Use a multimeter to check sensor/actuator resistance, voltage, and ground integrity.
Compare live data readings to factory specifications.
If circuit-related, trace the wiring diagram and test for opens, shorts, or high resistance.
Clear the code and perform a road test to verify repair.

Recommended Repairs

Replace or repair the faulty HO2S Heater (Bank 2 Sensor 3) if testing confirms failure.
Repair any damaged wiring, connectors, or terminals. Ensure proper routing and secure mounting.
Clean components (throttle body, MAF sensor, EGR valve) if contamination is present.
Update ECM/TCM software if a technical service bulletin (TSB) applies.
Replace related fluids (transmission fluid, coolant) if degraded or incorrect.
Verify repair by clearing codes and completing an extended road test under various conditions.
