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.
