P0313 Code: Misfire Detected with Low Fuel
CodePage.genericDisclaimer
Was bedeutet das?
Code P0313 indicates engine misfires have been detected while the fuel level is very low.
Diagnostic system: Misfire and combustion
On a Honda Pilot, the P0313 code should be diagnosed as part of the misfire and combustion group. Related codes and live data from this same system can change the repair priority, so avoid replacing parts from the code name alone.
Most Common Causes for Honda Pilot
- Schwache oder defekte Kraftstoffpumpe
- Verstopfter Kraftstofffilter
- Verstopfte oder defekte Einspritzdüse
Zu beachtende Symptome
- Motorkontrollleuchte leuchtet
- Fehlzündungen oder Ruckeln des Motors
- Unruhiger oder instabiler Leerlauf
- Motor geht unerwartet aus
CodePage.beforeReplacing
- Check spark plugs, coils, injector balance, and compression before replacing expensive parts.
- Review freeze-frame RPM/load to see when the misfire occurs.
- Look for fuel trim or vacuum leak codes that can cause multiple-cylinder misfires.
- Check for blown fuses, weak battery voltage, and damaged connectors before buying major parts.
Wie man diagnostiziert
CodePage.commonMistakes
Replacing ignition coils without moving coils, checking plugs, or confirming fuel and compression are healthy. Always confirm the fault with freeze-frame data, live data, visual inspection, and circuit checks before spending money on parts.
CodePage.faq
Can I drive with the P0313 code?
If the check engine light is solid, you can usually drive to a safe location or mechanic. If the light is flashing, pull over immediately to prevent catastrophic engine or catalytic converter damage.
Will the P0313 code clear itself?
Once the underlying problem is fixed, the engine computer will run its self-checks. If it passes over several drive cycles, the light will turn off automatically. You can also clear it immediately using an OBD2 scanner.
Will this code fail an emissions test?
Yes. If the Check Engine Light is on due to the P0313 code, your Honda will automatically fail an OBD2 plug-in emissions or smog test.
What should I check first for P0313?
Check spark plugs, coils, injector balance, and compression before replacing expensive parts. Review freeze-frame RPM/load to see when the misfire occurs. Look for fuel trim or vacuum leak codes that can cause multiple-cylinder misfires.
