2000 dodge caravan 3.0 engine code po1391 crankshaft position sensor or camshaft position sensor but engine has distributor?

Hi mate start at the easiest point which will be to check your EARTH to make sure everything is earthed.

P0017 Dodge - Crankshaft-Camshaft Timing Misalignment Bank 1 Sensor 2Possible causes - Engine oil dirty
- Incorrect engine viscosity
- Crankshaft position sensor circuit is open or shorted
- Camshaft position sensor circuit is open or shorted
- Faulty crankshaft position sensor
- Faulty camshaft position sensor
- Timing gear misalign

The 1391 most likely is the cam sensor or crank sensor, crank sens is located in the bell housing on the pass side and I believe the cam sensor is in the distributor, 740 is a TCC (Torque Convertor Control) performance code. The crankshaft sensor is my 1st choice, TCC performance is calculated comparing engine speed to vehicle speed.

follow this link it shows a great pic of its location.

P0016 Chrysler

Crankshaft -camshaft timing misalignment bank 1 sensor 1
- The pcm detects that the camshaft position is out of phase with the crankshaft position

Probable Cause[s]

1. Engine oil dirty or contaminated /Incorrect engine viscosity
2. Open or short circuit condition
3. Camshaft 1/1 position solenoid, camshaft phaser ,camshaft1/1 position sensor
4. Crankshaft position sensor ,crankshaft,tone wheel or flex plate
5. Camshaft,tone wheel or pulse ring

po 1391 is crankshaft sensor or cam sensor change crankshaft sensor

check your camshaft position sensor

Code P1391 is Intermittent loss of the Camshaft Position Sensor (CMP) or the Crankshaft Position Sensor (CKP).
What size engine? 3.0L, 3.3L 3.8L?
For a 3.8L:
The Camshaft Postion Sensor is located on the top of the timing chain cover on the front of the engine on the right side of the Van. It is located below the Large accordian hose coming from the air filter box to the Throttle, looking straight down. You have to remove the 10mm bolt attaching it to the engine block, and pull it out. Do not pull on the wires. Disconnect the wiring connection. It has a rubber o-ring and is pretty snug in the hole, Because of it's location, it may be a little difficult to pull-out.
The Crankshaft Position Sensor is located on the back part engine right adjacent to the area of the Transmission Bell Housing. Remove the Battery and Battery Tray to more easily access.
It will be around $100-110 dollars to replace both.
Make sure when you replace one with a new one to put clean engine oil on the rubber o-ring to ease installation.

Hello! The DTC P0016 inidicates a cranskshaft and camshaft misalignment. If you only replaced the camshaft position sensor - you may need to replace the crankshaft position sensor - which is located at the top where the engine and transmission connect.


Hope this helps and good luck! Thanks for using FixYa!

The camshaft position sensor is located under the hood in the center rear engine area, mounted on the rear center of cylinder head on the 3.0L Caravan. Hope this helped and best wishes.
