My wife's 01 Intrepid ES overheated about a week ago so she pulled over and shut it down, I got there topped off the antifreeze to get it home, it wouldn't start back up, I ran the codes and got P0340. Weather finally warmed up so I replaced the sensor, cleared the codes and it won't start, threw P0340 code again. The sensor the parts store gave me is loose in the hole where the original was quite tight, is it possible they gave me the wrong one? I could understand overheating making an 18 year old sensor give out I guess, anyone have any ideas, the Chiltons manual says "No Fuel Sync" under description of diagnostic trouble code for P0340 and "No cam signal at PCM" under DRB scan tool display. They put some real thought into making a 5 minute job take much longer by putting the intake directly above it.

You really should get an OEM sensor from the dealer. The aftermarket sensors are known to be crap. Another or additional possible cause of your issue maybe the Crankshaft Position Sensor is crapping out also.

Another thing to try would be try to start it with the cam position sensor disconnected (Electrical Connector). If it starts and runs up to about 2000-2500 rpm then it's a bad Camshaft sensor. A No Start all is commonly the Crankshaft Sensor.

I just saw it's a 3.2/3.5L engine. When was the last time the timing belt was changed? What was the Actual Cause of the Overheat condition? It's quite possible your Timing belt broke. What does it sound like when it's turning over? Normal?

Well I unplugged it, and it came close to starting but didn't, closer than with it plugged in, will probably just invest in a crank sensor anyway. Could the overheating have caused the sensor to crap out, or is it just coincidence that they happened at the same time?
