What Does P2067 Mean?
The control module has detected abnormally low voltage or resistance from fuel level sensor B circuit, indicating the sensor is reading at or near empty position constantly. This suggests a short to ground or internal sensor failure.
Common Causes
35%
Wiring harness shorted to ground between sensor and control module
30%
Failed fuel level sensor with internal short or resistor card failure
20%
Damaged or corroded connector pins causing short to ground
10%
Float arm stuck in empty position due to mechanical binding
5%
Fuel contamination causing conductive deposits on sensor components
Diagnostic Steps
1
Step 1: Disconnect fuel level sensor B connector and measure resistance; should show infinite resistance to ground
2
Step 2: Measure voltage at control module connector on signal wire with sensor disconnected; should read approximately 5V
3
Step 3: Inspect wiring harness routing for pinch points or areas of chafing that could cause ground short
4
Step 4: Remove sensor and inspect float arm for binding and resistor card for damage or shorting
5
Step 5: Perform resistance sweep test by manually moving float through entire range while monitoring ohms
Estimated Repair Cost
$200 - $600
Parts + labor, varies by vehicle and location
The control module has detected abnormally low voltage or resistance from fuel level sensor B circuit, indicating the sensor is reading at or near empty position constantly. This suggests a short to ground or internal sensor failure.
The most common cause of P2067 (Fuel Level Sensor "B" Circuit Low) is: Wiring harness shorted to ground between sensor and control module
Typical repair costs for P2067 range from $200 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive but fuel gauge will incorrectly show empty or very low. Driver must manually track fuel consumption to avoid running out of fuel.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2067 to identify the root cause.
