The P2067: Fuel Level Sensor ‘B’ Circuit Low refers to a fault where the fuel level sensor ‘B’ circuit is experiencing low voltage. This sensor monitors the fuel level in the tank and sends this information to the vehicle’s control module. Low voltage in the circuit can lead to inaccurate fuel readings and may be caused by a faulty sensor, wiring issues, or connector problems.
P2067 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2067: Fuel Level Sensor ‘B’ Circuit Low |
| Is it serious? | No, but it can cause incorrect fuel level readings, potentially leaving the driver unaware of the actual fuel level. |
| Possible causes | – Low voltage in the sensor circuit – Faulty sensor – Wiring or connector issues |
| How to diagnose? | – Measure voltage in the sensor circuit – Test the sensor – Inspect wiring and connectors |
P2067 Meaning
The P2067 code indicates that the fuel level sensor ‘B’ circuit is receiving low voltage, which can cause the sensor to provide incorrect readings of the fuel level in the tank. This issue may result in an inaccurate fuel gauge, causing the driver to misjudge the remaining fuel. The low voltage could be caused by a fault in the wiring, connectors, or the sensor itself.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional fault codes related to the fuel system that might provide more context on the issue. | OBD-II Scanner |
| Measure Voltage in the Circuit | Use a multimeter to measure the voltage in the fuel level sensor ‘B’ circuit and compare it to manufacturer specifications to confirm if it’s low. | Multimeter |
| Test the Sensor | Use a diagnostic tool or multimeter to test the fuel level sensor for proper operation and ensure it’s working within the expected voltage range. | Multimeter, Diagnostic Tool |
| Inspect Wiring and Connectors | Check the wiring and connectors leading to the fuel level sensor for any signs of damage, corrosion, or loose connections that could cause low voltage. | Flashlight, Multimeter |
| Clear the Code and Test Drive | After repairs, clear the code using an OBD-II scanner and perform a test drive to ensure the problem has been resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure that the P2067 code does not return. If it reappears, further diagnostics may be necessary. | OBD-II Scanner |
