‘00 Dodge Durango, Over Seas P-Codes
Q: I have a ‘00 Dodge Durango and I am stationed overseas. I have a few p-codes for the computer and I don't know what they are. I have P0123; P0207; P0208. I also have P300, 301, 303, 304, 305 and 306. I do know that the latter are misfires, but have no clue on the first three. I did just return from a trip traveling thru the Alps, hope I didn't kill her. She has had a hard time starting a couple of times but not every time, that is why I checked the codes. Being overseas there is just no one who can tell me what is wrong. I really hope you can help.
A: The P300 codes you listed are for an engine misfire condition. The P0123 is for the throttle position sensor voltage being too high. This code can cause a pile of driveability and even starting problems. The P0207 and P0208 for injector control circuit problems with cylinders #7 and #8. I would suggest checking the throttle position sensorís voltage readings. When the throttle position sensor goes amuck, it can raise havoc causing other codes to be set falsely. If the throttle position sensor checks out okay then clear the code and drive the vehicle to see which code returns first. Then have that computer code diagnosed first.
