Have you replaced your crank sensor?

The crank sensor queston comes up from time to time on high mileage/old Rivieras. I though it might help people to know when folks replaced theirs, becaue the sensor's failure is so tough to diagnose.

So - please post the date and mileage at which you replaced your crank sensor.

I replaced mine at 165,980 miles on 6/8/2007.

The crank sensor (10456161) was replaced on 10/29/2007 with 223,079 miles.

What do we post if we've never replaced them? Current mileage? (140,000) Or just wait until it needs changing, then post here...

replaced mine 3/10/07 at 125000 miles

thanks guys, keep posting.

If you've never replaced cranksensor, just post current miles on the odometer and "not yet" or some such.

Point is that I am suspecting that "crank sensor craps out at so and so mileage" that I was told (and have been repeating) might be BS. I don't like BS not even my own - and the only way I knew how to Come Clean was to ask us all to take a moment plese and post some actual data. Then we can jsut look at the data and make up our own minds.

Thanks

203,000 when I took the car apart for dirt circle track racing and as far as I know, never been replaced!! (knock on wood)

Ps. First year racing the Rivi SC and 2nd in points at 2 local tracks!! Not bad...

112k a still waiting.

knock on wood

Here's a laugh for ya.

62,XXX miles.

Replaced in November after a many trials to figure out why it wouldn't turn over.

Replace Crank Sensor and Harmonic whatchamacallit

Cost around $600, but now starts every time.


The Riv I just bought was rarely used by the original owner and even less used by the guy I bought it from. And seeing as it is a 1995, things were apt to go awry for $1350.

But again, all is good now. Highly recommend suggesting it to the mechanic before he 'tries' his methods.

95k and not yet.

Thats great!

Is there enough left to race it again next year? I bet that Buick is rough on them little cars.

80k miles and not yet

103000 and not yet

replaced at 147k mi when the majority of my mods were done but it was working fine when I did the swap....just wanted to be safe.

OK my impression so far is:

"Crank sensor craps out at so and so mileage" is not a good rule of thumb - but

"if you have a no-start with no codes set, replace the crank sensor" is a very good bet.

Further comments?

Not yet 229,000

Mine just threw a code on the way to dinner. It was like it couldn't decide to shift (lurched a bit). Probably the crankshaft sensor. It's the only code I've gotten, and I've gotten it a couple times.

162000 not yet but plannin on it soon just as precaution

261,000 miles on the original crank sensor. When I had the engine rebuilt 15k ago, the builder checked the sensor and recommended it not be replaced. Considering he's in the business of replacing parts, I didn't question his decision.

Be careful of the replacement, A friend who fixes Turbo Buicks bought 5 from Rockauto and 4 were bad, they were grooved and or warped,

Yeah, I have no reason to think my OEM will ever fail. Lucked out, I guess.

The original is probably better than any replacement piece and might outlive the rest of the car. Not something to replace as a maintenance piece.
