How to change the camshaft position sensor on a 2004 dodge neon s

hi Stephanie.
this is all i could find.go to this link and it might help you out.
2004 dodge neon stuck in second gear Google Search

Trouble Code: P0340

No Camshaft Position Sensor Circuit Failure
Possible Causes:


CMP Sensor connector is damaged, open or it is shorted CMP Sensor signal circuit is open or shorted to ground or to battery voltage or 5v supply circuit CMP Sensor 5v supply circuit is open or shorted to ground or to battery voltage CMP Sensor ground circuit is open CMP Sensor is damaged or has failed CKP Sensor is damaged or has failed PCM has failed

disconnect the negative battery cable. the cmp sensor is located on the left end of the cylinder head. move thebrake booster hose and electrical wires out of the way to access the cmp sensor. disconnect the sensor plug by pushing the locking tab back toward the firewall. remove the 4 bolts from sensor and lift out sensor. remove the trox bolt which holds the target magnet to camshaft. when installing target magnet be sure to line up holes to dowels on end of camshaft. torque torx bolt to 30 in-lbs. be sure to install new o-ring on sensor and torque bolts to 80 in-lbs.

A code P0340 could mean one or more of the following has happened:

• a wire or connector in the circuit could be grounded/shorted/broken
• the camshaft position sensor may have failed
• the PCM may have failed
• there exists an open circuit
• the crankshaft position sensor may have failed

With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

• Visually inspect all the wiring and connectors in the circuit
• Check for continuity in the circuit wiring
• Check the operation (voltage) of the camshaft position sensor
• Replace the camshaft position sensor as required
• Check the crankshaft position circuit as well
• Replace circuit wiring and/or connectors as required
• Diagnose/replace the PCM as required

Hope this is for any assistance.

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.I hope this helps you

Thanks.

on a neon the cam sensor is located at the drivers side of the engine on the end of the head. it mounts directly over the end of the front camshaft. it is about 3 inches wide and about 2 and a half inches tall. its made of black plastic and has a wire conector in the back of it. these very comonly leak oil so be careful of the o ring and cleaning the mounting surface.

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

HEY DUDE I JUST HAD THE SAME PROBLEM!!!!!!! TIMING BELT DONT DRIVE IT TOMUCH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! EVERY LIKE30,000 TO 90,000 CHANGE EM!!!!!

Had the same problem before on my 04 Neon SXT...camshaft sensor is on left side of engine block, take out the battery and to the left of it (face car) is the camshaft position sensor. To change it you'll have to move a few hoses but its plan to see there on the left side of the engine...pretty easy remove and replace. Fixed my problem of car not going above 2k RPM when i replaced the sensor.
