Try the Standard Motor Products sensor. They are *usually* pretty good on quality.

 

alright i installed the new part, but with mixed results.

sounds like the engine is running quieter and is not having the issue of jerking while in 35-45mph range.

that being said the stalling just after start issue went from infrequent to frequent (1 out of every 4 starts) and the check engine light is on and still says P1391. i cleared the codes and it came back after the next start. thoughts?

 

Time to check the wiring for the cam and crank sensors.

 

And I would start by inspecting the connectors at the ECM if it's like my 1999.

 

alright after a long break, I'm back. I ended up having to replace the pick up coil again as the one I first bought actually caused the engine to stall often. I swapped it to another one but I'm once again getting p1391 after I drive for about 50 miles.

I did try to check the wiring last night. there's nothing obvious although the wires are all taped together and I don't feel super confident about going that deep with my inspection. the wires look like they are in good shape on the harness and on the connectors going into ECM.

I called a shop and they told me this same thing, they have to inspect the wires for $125 per hour.

I was wondering...if there's a "computer issue", would you look to the ECM? or TCM? does this van have a replaceable TCM?
and is there anything I should try with my scan tool besides the engine code?
anyone recommend I throw a Hail Mary and just buy a new ECM? looks like I can buy it and plug it in, and if it doesn't work return it and just lose $50. any off the cuff guesses of % chance it's the computer?

thanks happy friday!

 

Might be the crank sensor that is causing the issue...... The code is for either cam or crank, intermittent signal.... Since you have been thru a couple cam sensors, might be time for the crank sensor. Unfortunately, the ONLY ones that work worth a darn are the mopar sensors....... which are not cheap. The aftermarket fellers tend to cause more problems than they solve.

 

ah I should have included that: I've already replaced a mopar crank sensor as well
and the IAC module, distributor cap, rotor, spark plug wires, air filter, pcv and hose

 

just found an oem cam sensor on ebay so I’ll try swapping that in too. still curious about the other questions if that fails

 

What year is the van?

 

year 2000
