I have a 83' spider that needs a new crankshaft position sensor. I was wondering if anyone knew of someplace in the Northeast L.A., Pasadena, Glendale, Burbank area where I could purchase one?

Just to clarify, your L-jet Spider has two flywheel sensors. They are the same but must be connected to the wire harness correctly. The L-jet Spider Diagnosis page (link below) has the info).

As to where to get new ones, you'll probably need to mail order them. All the usual Alfa parts suppliers should have them. But be prepared to pay $75-$100 (each). I have read that you might be able to get them for less from a place that has parts for VW's. But I haven't done that so I can't say for sure.

I know there are two of the sensors, are they different? everywhere i have looked them up they only show one so I have been assuming they are the same (one for ignition and one for injectors)

Yes, they are the same. One is for position (timing) the other for speed (RPM).

I've seen a couple of posts lately about the crankshaft position sensors.

Are these prone to fail ? In other words should I proactively replace mine just to avoid future problems ?

Everything is running fine right now.

Thanks,

I don't know if I would replace them if they ain't broke. But you might consider having a spare on hand in case one does. If one goes, the car won't start.

We got a sensor for a bmw, it works perfectly, unfortunatly after getting that resolved, come to find out my ECU is bad.

My mechanic found one online for $180.00. That didn't sound too terribly bad so i told him to get it. Depending on where it is coming from I should know by midweek whether or not my problems are all resolved.

I hope so, it's been in the mid 80's and it's time for some top down transit!

I hope that solves the problem. ECU failure, while possible, isn't the most common issue these cars have.

When I got my 84 in 2013, it would not start. It turned out to be the sensor cable, it was totally open.
A quick online search for part "Bosch 0261210001" brought up lots of online results.
I replaced both as one was in fact faulty and the 2nd one was perished at the bell housing end. I kept it for a spare.
I bought mine from:
Auto Parts at AutohausAZ - OEM Auto Parts - Discount Replacement Parts, Resources and Car Care Tips

Be sure to snug up the bolt at the bell housing end, but do not over tighten and its a good idea to check the bolt in a few months to ensure it has not vibrated loose.
Ask me how I know??? :)

Good Luck!

Eric, the last poster was just biting on my remarks about how do I know about the sensor coming loose at the flywheel...
I replaced mine and about 3 months later I started getting intermittent failures to start. I finally double checked my work only to find the bolt had come loose to the point where the sensor was no longer able to work and once I re-tightened it, its been business as usual.

lol - good advice though. I had the same issue a couple of years ago and talk about frustrating to troubleshoot! Mine would cut out intermittently on fast right-hand turns! How the heck do you simulate that in your driveway to troubleshoot? Never did solve it until the sensor fell off altogether and the car stopped on the side of the road!

Lol, I guess humor has no place in troubleshooting but what the hell. If I couldn't laugh at the whole thing I most likely would tear up my back trying to push the car off a cliff........... BECAUSE IT WOULD NOT START!!!!!!!!!!!!!!!!!!!!

Well it turns out that the problem was the ecu. Although the one I found for $180.00 was the wrong one, My mechanic got the right one for $300.00, the sensor was $48.00 and I was only charged $105.00 labor for everything done and out the door! I had read that this guy was incredibly reasonable but I was actually shocked by what he charged me! The car is running better than it ever has I am still grinng ear to ear!

AN ECU AND CRANKSHAFT SENSOR DIAGNOSED AND REPLACED FOR $453.00!

well done and congrats..
I went to a local import shop after purchasing my Spider and they wanted $600 just to set the valves...
Needless to say I found another source who is an AR specialist and was a portion of the price.
