Check These First (Before Buying Parts)

  • Visually inspect the wiring and connector for Bank 2 Sensor 3 for any obvious damage, fraying, or corrosion.
  • Check your vehicle's fuse box for any blown fuses related to the O2 sensor heaters (though a blown fuse is less likely for a 'high' circuit code).

How to Diagnose P0062

  1. 1Visually inspect the wiring and connector for Bank 2 Sensor 3 for any signs of damage, corrosion, or shorts.
  2. 2Using a multimeter, check the resistance of the heater element within the oxygen sensor itself (unplugged). Compare to factory specifications.
  3. 3Check for voltage supply to the oxygen sensor heater circuit at the connector with the key on.
  4. 4If the sensor and wiring check out, further diagnosis of the ECM/PCM may be necessary by a professional.

P0062 on Popular Vehicles

Toyota Camry

2007-2024

P0062 is not a code with a specific common pattern for the Toyota Camry. However, O2 sensor heater circuits can fail on any vehicle due to age and heat exposure. Bank 2 Sensor 3 is typically the downstream sensor on the rear bank (V6 models) or the second downstream sensor if applicable.

75% fixed by replacing the oxygen sensor

Honda Accord

2003-2024

Similar to other vehicles, P0062 on a Honda Accord points to an electrical issue with the Bank 2 Sensor 3 heater. These sensors are exposed to extreme heat and can degrade over time. Always check for wiring damage first, as Honda harnesses are sometimes prone to rodent damage.

75% fixed by replacing the oxygen sensor

Ford F-150

2004-2024

On Ford F-150 trucks, especially V8 models, Bank 2 Sensor 3 is the downstream O2 sensor on the passenger side. The location can make it susceptible to road debris or exhaust leaks affecting the wiring. A faulty O2 sensor is the primary cause for P0062.

Frequently Asked Questions

What does P0062 mean?

P0062 indicates that the engine computer has detected a higher than normal voltage in the heater circuit for the oxygen sensor located after the catalytic converter on the second bank of cylinders (Bank 2 Sensor 3).

Can I drive with P0062?

Yes, you can drive safely with P0062. This code primarily affects emissions and fuel economy. There are no immediate safety concerns, but you should fix it within 1-2 weeks to prevent long-term issues.

Will P0062 clear itself?

No, P0062 will not clear itself. The underlying electrical fault in the oxygen sensor heater circuit or wiring must be repaired before the code will clear. After the repair, you can clear the code with a scan tool, or it will clear after several drive cycles if the fault is gone.

How do I fix P0062 myself?

Start by inspecting the wiring and connector for Bank 2 Sensor 3. If no visible damage, test the resistance of the oxygen sensor's heater element with a multimeter. If the sensor is faulty, replacing the Bank 2 Sensor 3 oxygen sensor is the most common fix.

How much does it cost to fix P0062?

If you do it yourself, replacing the oxygen sensor typically costs $50-$200 for the part. A professional repair, including parts and labor, usually costs $150-$500, depending on the vehicle and shop rates.

P0062 keeps coming back - why?

If P0062 keeps returning, it indicates the initial repair did not address the root cause. This often happens if the wiring harness was not thoroughly checked for shorts, or if the problem is an intermittent fault in the wiring or, less commonly, the engine computer itself.

Will P0062 fail emissions/smog test?

Yes, P0062 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on, regardless of the specific code, is an automatic failure in most states that require inspections.

What's the difference between P0062 and P0060/P0061?

P0062 indicates a 'high' voltage condition in the O2 sensor heater circuit. P0060 indicates an 'open' circuit (no continuity), and P0061 indicates a 'low' voltage condition. All three point to an issue with the O2 sensor heater circuit, but they describe different electrical faults.

P0062 on Ford F-150?

While P0062 is not specific to the Ford F-150, oxygen sensor heater failures are common wear items across all vehicles, including the F-150. The diagnostic steps remain the same: inspect wiring, test the sensor, and consider the PCM if other checks pass.

Questions to Ask Your Mechanic

Did you check the resistance of the O2 sensor heater element for Bank 2 Sensor 3?

Good answer: Yes, I measured the resistance and it was outside the specified range, indicating a faulty sensor. Or, 'The resistance was good, so I moved on to checking the wiring for a short to voltage.'

What did you find when you inspected the wiring harness for Bank 2 Sensor 3?

Good answer: I found a section of the wiring that was chafed and shorting to a power wire, which caused the high voltage. Or, 'The wiring looked clean and intact, with no signs of damage or corrosion.'

Intermediate - requires a multimeter and specific O2 sensor socket, along with basic electrical diagnostic skills.

Cost of Waiting

Ignoring P0062 means your engine runs with incorrect fuel mixture data, leading to reduced fuel economy and increased emissions. Over a long period, this can cause premature failure of your catalytic converter, turning a $50-$200 sensor replacement into a $800-$2,500 converter job.

While You're In There...

Exhaust Gaskets

If you need to remove exhaust components to access the sensor, replacing old gaskets prevents exhaust leaks and ensures a proper seal.

Anti-Seize Compound

Applying anti-seize to the new O2 sensor threads prevents it from seizing in the exhaust, making future removal easier.

Tools You'll Need

  • OBD-II Scan Tool
  • Multimeter
  • Oxygen Sensor Socket (7/8 inch or 22mm)
  • Ratchet and extensions
  • Wire brush (for exhaust threads)
  • Anti-seize compound

Related Codes

P0062 is a common electrical code related to an oxygen sensor. The repair is usually straightforward, often just replacing the sensor, and your vehicle will run more efficiently afterward.

Your Next Steps

1

Step 1: Perform a thorough visual inspection of the Bank 2 Sensor 3 wiring and connector. Look for any signs of melting, chafing, or corrosion.

2

Step 2: If the wiring looks good, use a multimeter to test the resistance of the O2 sensor's heater element. Compare your reading to the factory specification (usually a few ohms). If it's open or very high, replace the O2 sensor.

3

Step 3: If the sensor's heater resistance is good, check for a short to voltage in the wiring harness leading to the sensor. This may require disconnecting the PCM connector and checking continuity to power sources.

Note: Bank 2 refers to the side of the engine that does not contain cylinder #1. Sensor 3 refers to the oxygen sensor located after the catalytic converter on that bank.
