1% of P0067 cases are fixed by replacing the PCM
Check These First (Before Buying Parts)
- Check all fuses in your vehicle's fuse box, especially those labeled for O2 sensors or engine control.
- Visually inspect the wiring harness leading to the Bank 2 Sensor 3 oxygen sensor for any cuts, fraying, or signs of rodent damage. Also, check the connector for corrosion or bent pins.
How to Diagnose P0067
- 1Check for any blown fuses related to the O2 sensor heater circuits in your vehicle's fuse box.
- 2Visually inspect the wiring harness and connector for the Bank 2 Sensor 3 oxygen sensor for any signs of damage, corrosion, or loose connections.
- 3Using a multimeter, test the resistance of the heater element within the Bank 2 Sensor 3 oxygen sensor. Compare to factory specifications.
- 4With the ignition on, check for proper voltage and ground at the O2 sensor connector to ensure the PCM is supplying power correctly.
- 5If the sensor's heater resistance is out of spec or power/ground are correct, replace the Bank 2 Sensor 3 oxygen sensor.
P0067 on Popular Vehicles
Ford F-150
2004-2024On V8 F-150s, Bank 2 Sensor 3 is typically the downstream O2 sensor on the passenger side exhaust, often after a secondary catalytic converter. Access can be challenging due to exhaust routing.
80% fixed by replacing the O2 sensor
Chevrolet Silverado
2007-2024For V8 Silverado models, Bank 2 Sensor 3 is usually the post-catalytic converter sensor on the driver's side. Wiring issues are slightly more common on these models due to routing near exhaust components.
75% fixed by O2 sensor, 15% by wiring
Toyota Tundra
2007-2024On V8 Tundra models, Bank 2 Sensor 3 is the downstream sensor on the passenger side. These sensors are generally reliable, so always check for exhaust leaks near the sensor or wiring damage before replacing the sensor.

Frequently Asked Questions
What does P0067 mean?
P0067 indicates that your vehicle's computer has detected a high voltage condition in the heater control circuit for the Bank 2 Sensor 3 oxygen sensor. This sensor is located on the second bank of cylinders, typically after the catalytic converter.
Can I drive with P0067?
Yes, you can drive safely with a P0067 code. This code primarily affects emissions and fuel economy, not immediate drivability. However, you should fix it within 1-2 weeks to prevent further issues.
Will P0067 clear itself?
No, P0067 will not clear itself. The Check Engine Light will remain on until the underlying issue with the oxygen sensor heater circuit is diagnosed and repaired. You will need to clear the code with a scan tool after the repair.
How do I fix P0067 myself?
To fix P0067 yourself, start by checking fuses and visually inspecting the wiring to the Bank 2 Sensor 3 oxygen sensor. If those look good, use a multimeter to test the resistance of the O2 sensor's heater element. If it's out of specification, replacing the oxygen sensor is the most common fix.
How much does it cost to fix P0067?
The cost to fix P0067 yourself is typically $50-$150 for a new oxygen sensor. If you take it to a shop, expect to pay $150-$500, which includes parts and labor.
P0067 keeps coming back - why?
If P0067 keeps coming back, it means the root cause wasn't fully addressed. This often points to a persistent wiring issue that wasn't properly repaired, a faulty connection, or, in rare cases, a problem with the Powertrain Control Module (PCM) itself.
Will P0067 fail emissions/smog test?
Yes, P0067 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on, regardless of the code, is an automatic failure in most jurisdictions. Additionally, a malfunctioning O2 sensor heater circuit can directly impact your vehicle's emissions.
What's the difference between P0067 and P0066?
P0067 indicates a 'Heater Control Circuit High' condition for Bank 2 Sensor 3, meaning the computer sees too much voltage. P0066 indicates a 'Heater Control Circuit Low' condition for the same sensor, meaning the computer sees too little voltage or an open circuit. Both point to an issue with the O2 sensor's heater circuit, but the specific electrical fault differs.
P0067 on Ford F-150
On a Ford F-150 (especially V8 models), P0067 for Bank 2 Sensor 3 typically points to the oxygen sensor located after the catalytic converter on the passenger side exhaust. Access can sometimes be tight, but the repair process is generally the same: check wiring and fuse, then replace the sensor if faulty.
Questions to Ask Your Mechanic
Did you check the resistance of the O2 sensor's heater element and compare it to factory specifications?
Good answer: Yes, the heater element resistance was out of spec at X ohms, confirming the sensor is faulty.
What did you find when checking for power and ground at the O2 sensor connector?
Good answer: We confirmed there is proper 12V power and a good ground at the connector, indicating the wiring to the sensor is intact and the PCM is supplying power.

Intermediate - requires a scan tool for code clearing, a multimeter for testing, and an O2 sensor socket for removal/installation. Access to the sensor can sometimes be challenging.
Cost of Waiting
Ignoring P0067 will lead to reduced fuel economy and your vehicle failing emissions tests. Over a long period, a consistently malfunctioning O2 sensor can cause your catalytic converter to operate inefficiently, potentially leading to premature failure of the converter ($800-$2,500 repair).
While You're In There...
If you need to remove any exhaust components to access the O2 sensor, it's smart to replace the gaskets to prevent future exhaust leaks.
Applying anti-seize to the new O2 sensor threads ensures it can be removed easily in the future and prevents damage to the exhaust bung.
Tools You'll Need
- OBD-II Scan Tool
- Multimeter
- O2 Sensor Socket
- Ratchet and Extensions
- Wire Brush (for rusted threads)
- Anti-Seize Compound
P0067 is a common code related to your emissions system. Most repairs involve replacing an oxygen sensor, which is a straightforward job that will get your engine running efficiently again.

Your Next Steps
Step 1: Check your vehicle's fuse box for any blown fuses related to the O2 sensor heater circuit. Also, visually inspect the wiring and connector for the Bank 2 Sensor 3 O2 sensor for any obvious damage.
Step 2: If fuses and wiring appear good, use a multimeter to test the resistance of the heater element on the Bank 2 Sensor 3 O2 sensor. Compare the reading to your vehicle's service manual specifications.
Step 3: If the O2 sensor's heater resistance is out of specification, or if you've confirmed power and ground are present at the connector but the sensor isn't heating, you'll likely need a new Bank 2 Sensor 3 oxygen sensor.
