Error code P2067 indicates that the engine control module (ECM) has detected a low voltage signal from the fuel level sensor B circuit. This usually points to a faulty fuel level sensor, wiring issues, or a problem with the fuel gauge. While the vehicle can still be driven, the fuel reading may be inaccurate, so it's important to diagnose and fix the issue promptly.

When to Call a Professional

If you are uncomfortable working around fuel, or if the code persists after checking wiring and replacing the sensor, it is best to have a professional mechanic diagnose the issue. Dropping the fuel tank can be complex and dangerous if not done properly.

Frequently Asked Questions

Can I drive my car with a P2067 code?
Yes, but your fuel gauge may be inaccurate. It's safe to drive short distances, but you should get it fixed to avoid running out of fuel unexpectedly.
What is fuel level sensor B?
Fuel level sensor B is typically the secondary sensor in vehicles with dual fuel tanks or saddle tanks. In single-tank vehicles, it may be an alternative designation for the main sensor.
How much does it cost to fix code P2067?
If it's a wiring issue, costs can be minimal (under $50). If the sensor needs replacement, parts can range from $50-$200, and labor (if you do it yourself) is free. Professional replacement can cost $300-$600.
Will a bad fuel level sensor trigger other codes?
Yes, it may also set codes like P2066 (Fuel Level Sensor B Circuit Range/Performance), P0463 (Fuel Level Sensor Circuit High Input), or P0462 (Fuel Level Sensor Circuit Low Input).
Do I need to drop the fuel tank to replace the sensor?
In most vehicles, yes. Some vehicles have an access panel under the rear seat or in the trunk, but many require tank removal. Check your vehicle's service manual.
