[QUOTE="Gary747, post: 429283, member: 19207"] I had a similar problem, but the crankshaft position sensor itself was fine. On mine, if you trace backwards from the sensor and up the wire, there is a connector for the sensor wiring near the back of the power steering reservoir. In my case, that connector had been installed with a broken "snap" latch so the connector would open up intermittently. Not "come apart", but internally "unconnect" if you will. I replaced the connector, but could have been creative with small wire ties. Another subject... I see you have the $6 Harbor Freight Digital Multimeter. I have about 5 of them myself, scattered around the house so as to be handy when needed. I like them, but I've had two meters fail... not he meter itself but the leads they use that plug into the front. The wire-to-probe connections are small and manufacturing quality is "iffy", so I would also get the "1" indication if the lead was not being held in a particular position for the internal wire to make contact. I tried to repair one of them, but found it easier to just buy a couple new meters on my next visit to Harbor Freight. I didn't even try to return them. Just a "for what it's worth" comment. One last comment... I don't think that the amount of dirt/oil your picture shows on the sensor surface is enough to cause your problem. Just wipe it off. However, when installing that connector, it needs to be secured (bolted) VERY close to the crankshaft dampener (.020 to .060 inch clearance), We're talking the thickness of a stiff piece of paper AFTER tightening it down. Do not overtorque. If you crack the sensor housing and/or bracket, it's a new sensor for you. Just for interest, I'll admit that I have a spare crankshaft position sensor on my parts shelf.
