OBD-II Error Code P0313: How to Fix It

Q: Can I drive with error code P0313?

It is not recommended to drive with P0313 because a misfire can damage the catalytic converter and reduce engine performance. If the check engine light is flashing, stop driving immediately.

Q: What causes P0313?

Common causes include low fuel level or pressure, a failing fuel pump, clogged fuel filter, contaminated fuel, vacuum leaks, or ignition system issues.

Q: How do I clear code P0313?

After fixing the underlying issue, use an OBD2 scanner to clear the code. Alternatively, disconnect the battery for 15 minutes, but the code will return if the problem isn't fixed.

Q: Is P0313 the same as P0300?

P0300 indicates random misfire without specific cylinder identification. P0313 adds the condition of low fuel. Both can stem from similar causes, but P0313 focuses on fuel delivery.

Q: Do I need to replace the fuel pump for P0313?

Not always. First, check fuel pressure and filter. If pressure is low after replacing the filter, the pump may need replacement. However, don't assume the pump is bad without testing.

Abstract

Error P0313 indicates that the engine control module (ECM) has detected a misfire condition while the fuel level is low. This typically means the engine is not running smoothly, and the misfire could be caused by low fuel pressure, a weak fuel pump, or contaminated fuel. This guide will help you diagnose the issue and apply common fixes.
