Just replaced cam sensor and crankshaft sensor, now the car is stuttering and backfiring upon taking off. I keep getting a code of 1684 (battery disconnect..) the battery has not been disconnected, anyone know what else this could mean?

    do you mean after replacing the sensors? I didn't fix it a buddy of mine did

  • talk3232 Dec 19, 2008

    do you think this could be the cause if he didn't set the air gap properly? I will find out and let you know...thank you for responding ( :

  • talk3232 Dec 20, 2008

    no...don't think that was done, the crank shaft sensor was a used one, a friend replaced it but doesn't have the time for it now...I only have limited knowledge of newer cars...please if you can offer any advice, I really need to get this fixed (:

That me your battery has been disconnected with in the last 50 starts!! so your buddy did disconnect the battery when installing it that's rite! sounds like maybe your EGR solenoid might be unplugged look for wires unplugged if you don't see any thing get a OBD 2 scanner and rescan for new codes!! appeared hope this helps!

It has a stutter when driving.

Check fuel pressure, and check for possible trouble codes. Autozone or O'reilleys will do free code scans. I think they also loan or rent fuel pressure gauges.

What are these codes p1779, 11780,po440,po341, replaced cam position censor

Try replacing the crankshaft position sensor. I had a 1998 dodge ram that had that same issue. Thats what it was.
Its by the flywheel under the vehicle. probably on the passenger side.

Where Do I start with a P0016 code on my 2005 Dodge neon (2.0L)

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.

My neon is showing a dtc code 1390, timing belt has skipped one or more teeth. Checked the timing marks and everything is as it should be, should I condemn the cam sensor, or the crankshaft sensor? Or is...

P1390 means cam/crank not in time. Probably slipped a tooth on the cam belt (Installed wrong most likely, easy to do) or, just a chance, cam timing sensor is bad. Take it apart and look ,if you bought the car this way you may have wrong or damaged timing gear,stick shift or automatic may have different shape where the sensor rides,

2005 dodge noen cam sensor

I own a 2002 neon sxt and recently had to replace the cam sensor it should be in the same place.
look on the right side of the motor you should see it. it'll have a small wire harness that clips in the top and its fastend with 4 bolts. Oh and take the battery out before you do it it makes it a lot easier.

Hope this helps.
