P0355 Chrysler - would this code also come up if i have a bad CKP sensor?

Question

two codes come up when I checked to see why the check engine light was on, po725 and po355. my jeep doesn't have any of the symptoms code po355 which is ignition coil #5. if I have a bad CKP sensor which is code po725 would that also cause code po355 to come up?

Answer 1

HI there,

A bad crank sensor will not cause a misfire code on a single cylinder. This means that although you may not feel it, at some point when you are driving it has a misfire on cylinder 5. More then likely it's a bad ignition coil that misfires at higher engine rpms. This might go unnoticed because when the engine speed is high enough it would still feel smooth.
