Default 2003 2.4 P0340 code....?

New to this site and fairly new to servicing Chrysler vehicles....PT has thrown a p0340 code, will start after 10 secs or so of cranking (hunting for timing). I pulled the connector off of the cam sensor and measured (key on engine off) 5V on pin 1, Ground on pin 2, and 5v on pin 3 which I understand is the signal input from the sensor. my concern is the 5v on pin 3..if the PCM is looking for a 0-5v input from the sensor??

Confused but looking forward to any input

thanks

Welcome to the forum.

P0340 - No Camshaft Position Sensor Circuit Failure Conditions:

Possible Causes:

Camshaft Position Sensor connector is damaged, open or it is shorted
Camshaft Position Sensor signal circuit is open or shorted to ground or to battery voltage or 5 volt circuit
Camshaft Position Sensor 5 volt circuit is open or shorted to ground or to battery voltage
Camshaft Position Sensor ground circuit is open
Camshaft Position Sensor is damaged or has failed
PCM has failed

You might want to check and see if the Camshaft Sensor is shorted out.

So..I replaced the camshaft sensor just out of curiosity so no more p0340 code. Now I have a p0344 code so I've checked the wiring to the pcm from the connector and the ckp sensor was replaced. So I'm saying it's either the target magnet or the pcm. Don't know what else to check

P0344 - Camshaft Position Sensor Circuit Intermittent Conditions

Possible Causes:

1. Wiring harness fault 5 volt supply circuit open or shorted to ground
2, Tone wheel/pulse ring is damaged or corroded
3. Camshaft Sensor has failed
4. Camshaft Sensor signal circuit is open, shorted to ground or battery voltage or 5 volt supply
5. Camshaft Sensor ground circuit is open
6. PCM has failed

Did you buy an after market Camshaft sensor?
Most of the time the target magnet is only replaced is when someone over torques the magnet when installing it.
