I have a 05 Convertable GTC with the 2.7l. Vehicle has 127K miles... It started cuttting out at 2750RPM like it wasnt getting any fuel. I pulled the code and it threw a P 0207... Only 6 injectors, so why 0207? checking the injectors and they weren't showing any problems. Kept driving... Then one day it began missing, badlly... Pulled codes, P 0207, P 0301. Misfire in Cylinder 1 with bad injector control circuit...
Long story short, I have replaced the Plugs, 1 coil pack, and moved to other cylinders to check, rechecked all injectors, moving to affected cylinder, and replaced the ECM following the advise of a Mechanic... No avail...
The Mechanic said the negative circuit in the ECM had failed causing the Injector and ignition coil not to fire....
Now, I have P0201, P 0301, P 0508, P 0123, P 0113, P 0108... and still a miss... By the way, the wiring between the ECM and the Injector and Coil Pack check out fine, and the Compression on affected cylinder is within proper limits....
Any Answers??? I'm stumped, as well as a lot of Mechanics....

 

Crank Position Sensor......... do a search, and you'll find many post that describe you same descriptions. Don't buy after market, they sometime die after a couple weeks, break down and get the OEM from the Chrysler Parts Counter
