Eeeek.... Fault Code P0301 - Misfire
 

On the same day I got a ScanGaugeII from the group buy, my CEL lit up. I checked the codes and found

P0340 = Camshaft Position sensor circuit malfunction.

...which and knew about and...

P0301 = Cylinder 1 Misfire detected

...which I didn't. Could it be related to the Cam Posn sensor? This is on a 03WRX.

P0301...... more likely to be related to the Neutral Position switch

Do a search, it well documented

Yep NPS was replaced and it is fixed.

;)

Yet another one - should be made a sticky :)
