My 2001 dodge neon cranked without the cam sensor connected. what's wrong with this picture?

It was not running due to timing out of spec. Get the right part

P0016-CRANKSHAFT/CAMSHAFT TIMING MISALIGNMENT
Does the car run? If it doesnt run it may have slipped time.If it does run, use a scope if available and check for a weak or erratic signal from the cam and crank sensors. The cam sensors routinely go out on these cars but a bad crank sensor can cause the code also.

Hello kriswdorsey,

Below are pictures of the cam position sensor and the crank position sensor. I hope this helps.

code 11 means intermittent loss of either camshaft or crankshaft position sensor. check connections to both sensors. also look for any damage to the wires connected to each sensor. either sensor will set off a signal to pcm of a no crank referance signal detected during engine cranking.

when you crank the engine over now, does it sound different than before? if yes, you probably have a broken timing belt. it is also common for the cam gear to slip out of position from the cam and cause an incorrect, but hard to diagnose, timing issue. other no start with check engine light on issues could be a faulty cam or crank sensor.

pull the codes from the vehicles computer. if there is a cam or crank sensor code, or if there is a code that says in some different wording "cam sensor signal does not match crank sensor singal", first check crankshaft to camshaft timing. if belt is ok and timing marks line up then i strongly suggest removing the bolt from the camshaft that holds the cam gear on. with the bolt and cam gear removed you should be able to tell if the cam gear has rotated on the camshaft. there should be a small pin sticking out of the camshaft. if it is broken off then you need to replace the camshaft. if the pin is still there and the timing is good then replace iether the cam or crank sensor depending on what code you have stored in the ecu memory. if the code is not for the cam/crank sensor then google search the code number e.g. "p0502" and your make and model.

2000 dodge neon cranks but wont start, but if i unplug the cam sensor it will run for a second

CODE PO340 NO CAMSHAFT POSITION SENSOR CIRCUIT FAILURE.CODE PO440 EVAP PURGE SYSTEM FAULT.POSSIBLE CAUSE THE EVAP PURGE VALVE VACUUM SUPPLY IS LEAKING OR CLOGGED.OR THE EVAP PURGE SOLENOID HAS FAILED.

YOU NEED TO CHECK DARK GREEN/ORANGE WIRE AT IGNITION COIL WHEN CRANKING ENGINE FOR POWER..IF NO POWER,SHUTDOWN RELAY IS NOT BEING ENERGIZED..THIS ENGINE ALSO HAS CAMSHAFT POSITION SENSOR ON END OF CYLINDER HEAD..ENGINE CONTROLLER NEEDS CAM AND CRANK SIGNALS TO ENERGIZE THE SHUTDOWN RELAY..UNPLUG CRANK SENSOR AND CHECK VOLTAGE ON ORANGE WIRE..SHOULD HAVE APPROX 8V..IF NOT..UNPLUG CAM SENSOR AND SEE IF 8V SUPPLY RETURNS..IF NO POWER TRY UNPLUGGING VEHICLE SPEED SENSOR LOCATED IN TRANS HOUSING WHERE RIGHT SIDE AXLE COMES OUT OF TRANS..IF 8V RETURNS..THE SPEED SENSOR IS SHORTED INTERNALLY..THESE 3 SENSORS SHARE THE SAME 8V SUPPLY CIRCUIT..WITH SPEED SENSOR UNPLUGGED,PLUG CRANK SENSOR BACK IN AND TRY TO START ENGINE..HAVE SEEN THIS SAME PROBLEM AT WORK RECENTLY

if you noticed hows theres not much slack in the pigtail connector to the cam sensor the wires can break at the bend. replacing the pigtail should fix it
