Source/Brand for good Crankshaft Position Sensor - CPS?

[Duncan Moody]

Having very intermittent/random stalling problem.  Starts and runs fine then completely dies on the road, won't restart immediately, then starts right up again after sitting 5 - 10 minutes.  Replaced CPS 2X, both brands (Standard and OMIX/ADA) both had less than .25VAC output.  Per Cruiser54's valuable tips, I should be seeing .5VAC, or at least above .35. 

 

Does modifying one of the CPS mounting holes and moving it closer to the flywheel increase output voltage?

 

Does anyone know a specific brand (part number if possible) that gives the correct voltage and a source?

 

Thanks.

Hey I have the same year, trim, engine, and tranny MJ as you do!

 

So I haven't actually replaced the sensor for my MJ yet but I have for my 1993 ZJ. I don't know if they are the same as what is used in the MJ but I used an NTK EH0245 from RockAuto. If there is one thing I have always practiced with sensors and electronic components; never go cheap. You get what you pay for, and getting lucky is never a good bet to be placed.  

 

NTK is a very reputable brand, and I believe they are a sub brand of NGK (think sparkplugs). I use NTK when I can't get official Mopar branded items, which is increasingly common. I'd go with them. 

 

As to the more technical aspect of your question, I would rather let a more knowledgeable person answer to it.

If you can, locate a Siemens CPS, they are an OEM manufacture for the CPS. They made them during the Chrysler era and probably during AMC's time too.
