I have a 2007 liberty 3.7 with a code p2302 I have good voltage at the coil 14+ also less than 5 ohms resistance on my blue and white wire from pin 10 thru the wore to ground . the plugs are worn but appear to be firing clean . wire test from the coil on blue and white to the connector at the pcm shows no open circuit,I suspect a bad PCM. This vehicle did have the engine washed and had a couple codes on cylinder 2 and 3 for a misfire due to water on the coils, they cleared up then this one I have now appeared
