P0313

Misfire Detected With Low Fuel

Ignition / misfire Generic OBD-II High

What it means

P0313 means the engine misfired while the fuel level was low. The ECM sets this code to flag misfires caused by fuel starvation — the pump drawing air when the tank runs near empty — rather than a purely mechanical fault. It often clears after refueling, but can also point to a weak fuel pump or clogged filter.

High

Can I keep driving? Refuel promptly — running the tank near empty causes fuel starvation and misfire; a sustained misfire can also damage the catalytic converter.

Common symptoms

What you'll notice

Check-engine light on
Misfire and rough running when the fuel level is low
Hesitation and reduced power on acceleration
Stumbling that eases after refueling

Common causes

Most likely first

Very low fuel level starving the fuel pump, especially on hills or hard corneringLikely
Weak or failing fuel pump / low fuel pressureCommon
Clogged fuel filter restricting flowCommon
Clogged or dirty fuel injectorsLess often
Worn spark plugs or ignition coils that misfire under lean conditionsLess often

How to diagnose & fix

Work through it in order

Refuel the vehicle and see whether the misfire clears — this is the first and cheapest step.
Read freeze-frame data and check for accompanying misfire codes (P0300–P0308).
Test fuel pressure at the rail; a pump that can't keep up when the tank is low is a common cause.
Inspect the fuel filter and injectors; replace or clean as needed.
Check spark plugs and coils if misfires persist with a full tank. Clear and re-test.

FAQ

Quick answers

Is it safe to drive with P0313?+

Keep the tank filled and drive gently. A misfire from fuel starvation can damage the catalytic converter if it continues, so don't run it near empty.

Can I just clear P0313?+

You can, but if the real cause is a weak pump, clogged filter, or a habit of running low, the misfire and code will come back.
