Misfire Detected in One Cylinder
I P0301 The scan tool indicates Diagnostic Trouble Code (DTC) PO3O1:Cylinder 1 misfire detected.
[F03021 1;," """n tool indicares Diagnostic Troubte Code (DTC) pO3O2: Cylinder2 misfire detected.
P0303 | ths sssn tool indicates Diagnostic Trouble Code (DTC) PO3O3: Cylinder3 misfire detected.
i P0304 | tne scan tool indicates Diagnostic Trouble code {DTC} PO3O4: Cylinder 4 misfire detected.
Doscription
Misfire detection is accomplished by monitoring the crsnkshaft speed with the crankshaft speed fluctuation sensor whichis attached to the crankshaft.
lf misfiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence, and DTCP0301, P0302, P0303 or P0304 will be stored. Then, after the m;sfire has ceased, the MIL witt come on.lf misfiring that increases emissions is detected during two consecutive driving cycles, the MIL will come on, and DTCP0301, P0302, P0303 or P0304 will be stored.
NOTE: lf some of the DTCS listed below are stored at the same time as a misfire DTC, troubleshoot those DTCS first, thentroubleshoot the misfi.e DTC.
