After I drive the car about 20-30 minutes into the freeway about goin 70 mph. It starts doin this hesitation movements and the engine lights comes on. It feels like it want's to stop when I press the gas padle down and it also feels like it jerks couple times, but then it drives normal in the next day and the engine light goes out. It only happens when the car is fully warmed up and it's been running in the freeway in a certain speed. Can you please help and let me know what you think what the problem could be.

Thanks

You said there is engine light. We need the code.
The engine may be missing, or there is a tps problem.
It can be anything be anything but when we have the code we will find the system that causing the problem

Trouble Code: P1391
CKP Or CMP Sensor Signal Intermittent
Possible Causes:
Camshaft Sensor is not installed properly
Engine valve timing is not within specifications
Perform a CKP and CMP Sensor relearn with the scan tool.
Tone wheel or pulse ring is damaged

Trouble Code: P1495
Leak Detection Pump Solenoid Circuit Malfunction
Possible Causes:
LDP power supply circuit from the ignition switch is open
LDP solenoid control circuit is open or shorted to ground
LDP assembly is damaged or it has failed
PCM has failed

Trouble Code: P1490
Low Speed Radiator Fan Relay Circuit Malfunction
Possible Causes:

LFAN radiator relay control circuit is open or shorted to ground
LFAN radiator relay power circuit is open (test power to IGN)
LFAN radiator fan relay is damaged or has failed
PCM has failed
if you have questions about testing or" how to" please let me know.

THanks for the reply. What does it mean? (Perform a CKP and CMP Sensor relearn with the scan tool) and (Tone wheel or pulse ring is damaged)
and were are the following parts located in the car?

(Camshaft Sensor)
( Engine valve timing )
(Tone wheel or pulse ring )
(Pump Solenoid Circuit)
(LDP power supply circuit )
(LDP solenoid control circuit )
(LDP assembly)
(PCM)
(Radiator Fan Relay Circuit )
(LFAN radiator relay control circuit )
(LFAN radiator relay power circuit )

Thanks once again,
sebastian

I forget to asked you, but if possible can you please help me how to test the LFAN radiator relay control circuit.

Thanks,

answer
if the crankshaft is bad and changed you will need a spesial scan tool so the new ckp can relearn. ( autoshop or dealer have that)so is the camshaft position sensor too. this is for the first code.
To test this sensor, you will need the use of an oscilloscope.
Visually check the connector, making sure it is attached properly and that all of the terminals are straight, tight and free of corrosion. Also inspect flywheel (6-cylinder) for damage, and replace if necessary.
The output voltage of a properly operating crankshaft position sensor switches from high (5.0 volts) to low (0.3 volts). By connecting an oscilloscope to the sensor output circuit, you can view the square wave pattern produced by the voltage swing

LFAN radiator relay is just a relay for the radiator left fan, located on the left side near the battery.
the best way to test a relay if you do not have a multimeter is to replace it with a good one.

The camshaft position sensor is mounted to the top of the timing case cover. The bottom of the sensor is positioned above the camshaft sprocket.

try to change the crankshasft position sensor. do one ting at the time., because there are 3 big codes, it is good to start with the most likely of the driveability problem you presented.

You mention that the (camshaft position sensor is mounted to the top of the timing case cover). My question is were is exactly is the timing case cover and the camshaft position sensor are located for dodge intrepid? If I understood you right, You also mention that (try to change the crankshaft position sensor one thing at the time). Is that mean that there are 3 crankshaft sensor that needs to be change or just one?

P.S.
Sorry for askin so much question. I'm in the position of learning about fixing cars.

Thaks once again,
sebastian

There more than one code on your vehicle, I was saying to deal with one issue at the time.
hope you can see the camshaft position sensor and the bolt that hold it to the engine block.
it will need to be disconnected first.
