Low-fuel misfire

A low-fuel misfire DTC can be set on 1995-present Mitsubishi vehicles, due to fuel aeration caused by low fuel level. This possible cause has been added to the diagnosis procedures for these DTCs.
DTC DESCRIPTION
P0300……………………Random/multiple cylinder misfire
P0301……………………Cylinder 1 misfire
P0302……………………Cylinder 2 misfire
P0303……………………Cylinder 3 misfire
P0304……………………Cylinder 4 misfire
P0305……………………Cylinder 5 misfire
P0306……………………Cylinder 6 misfire
The most likely causes for any of these codes include:
- Fuel aeration due to low fuel level
- Ignition system related parts failure
- Faulty crankshaft position sensor
- Incorrect air/fuel ratio
- Low compression pressure
- Skipping of timing belt teeth
- EGR system and EGR valve failure
- PCM failure
Check whether fuel may be aerated due to low fuel level. Check whether or not users have experienced the lack of fuel.
