Good question. Without a Bentley (or Bosch) book for your year I don't know
what the CIS-E III DPR value should be.
I got a value scrawled on scrap paper and was told: "check for this value"
that was for CIS-E 1987 4000Q 2.2L 5cyl.
Salvage ones I checked had higher than ~200 ohms and climbed towards
infinity: "Open circuit" those were "bad."
One with a rock steady value was what I bought from the junk yard and it made
all the difference. The one I used came from a VW quantum.
Anyone know the CIS -E lll value for the DPR should be? Vehicle is a 100.
