So I just got a new-to-me 2000 Durango with a 169k miles. Here is a pic in the Members Rides section: https://dodgeforum.com/forum/members...ml#post3581527

Yesterday, I picked it up from my brother. Before making the 120-mile trip home, I changed the oil, air filter and added a bottle of high mileage Techron to the fuel tank.

Initially, there was NO check engine light but I connected my code scanner anyway. It picked up P0302 Code: Cylinder 2 Misfire Detected.

Today, I ran a few errands in it before making the return trip home and then the check engine light came on. I figured I'd recheck the codes when I returned home thinking it was still the P0302 Code.

On the way home, I experienced the engine cutting out during heavier throttle maneuvers. Like trying to pass on steep mountain grades.

I made the 120-mile trip home just fine without any other issues. I just simply took it easy on the mountain passes.

When I returned home, I reconnected my scanner and this time picked up code P0320: Ignition / Distributor Engine Speed Input Circuit. It was only the one code and the PO302 seen from the day before was gone.

Couple other parts of the story is my brother, within the last two years, replaced the Crank Position Sensor. Also, the Cruise Control is not working if that could be related?

So I'm looking for suggestions on how to most efficiently diagnose and correct this issue.

Thanks in advance!

 

Does the Cruise light come on in the dash when you hit the button?

If your brother put an aftermarket CPS in there, you are going to want to change that out for a genuine Mopar part as a first step..... The misfire on 2 is likely related to that.

 

Yes, if depressed enough times, the cruise light does finally turn on. Once on, I may or may not be able to set the speed. And if/when the speed is set, it will randomly trip out of cruise.

Yes, it was a parts store brand which leads me to my next question. Do we know who makes these sensors for Mopar? Are they simply a re-boxed vendor part? Or does Moper make they're own? If I could buy the OEM vedor for half the price, I'd rather do that.

 

I don't know who actually makes them for Mopar.... Trick is, get the mopar part number, then do a google search on that number. You can *generally* find them cheaper online somewhere... just make sure it IS a GENUINE mopar sensor.

For the cruise, I wonder if your clockspring is failing....

 

Correction: I was mistaken on what sensor my brother replaced. Just texting with him now. He replaced the CAM sensor. NOT the crank sensor. Guess it's more clear now what I need to do.

He said when he'd pull up to a stop light, it would die. The CAM sensor fixed that. And he had no issues after that.

 

Is what the Jeep folks are saying. That NTK is the OEM manufacturer for Mopar. At least for Jeep crank position sensors. Perhaps the same for Dodge?

So over at Rockauto, the NTK sensor is $22.79 while the Mopar sensor is $95.99 for what may be an identical sensor off the same assembly line.

Can anyone confirm this one way or the other?

 

NTK has a pretty good rep.... so even if it isn't 100 accurate, it *should* help if the sensor is the problem.

 

Replaced the crank position sensor and the spark plugs with NTK sensor and NGK copper plugs. The PO320 code is... Gone! Runs more smoothly as well.

 

Good Deal.
