OBD-II Generic Error Code P2068: How to Fix It

Q: Can I drive with error code P2068?

You may drive short distances, but be aware that your fuel gauge may be inaccurate. Continuing to drive can cause stalling if the sensor fails completely. It's best to diagnose and fix promptly.

Q: Will a bad fuel level sensor cause no-start conditions?

Typically, a bad fuel level sensor does not prevent starting. However, if the sensor circuit is shorted, it can affect the ECM's fuel calculations, potentially causing hard starting or stalling.

Q: How much does it cost to fix code P2068?

DIY cost is low (sensor $20-$80, wiring repair $5-$20). Mechanic labor can add $100-$300. Always check warranty coverage.

Q: Is the fuel level sensor B the same as the main fuel level sensor?

In vehicles with dual fuel tanks or saddle tanks, sensor B is the secondary sensor. In single-tank vehicles, sensor B may refer to a second sensor in the same tank (if equipped) or an additional sensor for emissions.

Q: Can a bad ground cause P2068?

Yes, a poor ground at the sensor or ECM can cause high voltage readings. Always check grounds during diagnosis.

Abstract

Error code P2068 indicates that the engine control module (ECM) has detected a high voltage signal from the fuel level sensor B circuit. This usually means the sensor or its wiring has a problem. Left unchecked, it can cause incorrect fuel gauge readings and trouble diagnosing fuel delivery issues.
