P0340 Camshaft Position Sensor circuit fault. My brother's 2002 GT gave him this code and started running crappy. Anyone got any ideas? He's got a cold air intake and a couple of other basic mods but it's been fine until now.
Thanks.
Thanks.
Sounds like one of the cam position sensors is toast. You'll have to change it out, it's inside the valve cover. Don't know any other quick fixes unless it's just come loose.
