Default Crank Sensor

I ran a diagnostic on my 1990 Bonneville LE, and i got that the crank sensor is damaged and the magnet is...well...missing....this is probably something im not going to mess with so could anyone give me some ideas of a general price range for a repair like this?

I know prices differ depending on your area but im just looking for a general price range area. Thanks for the help in advance.

Can't speak to price but expect it is well under an hour job with the right tools and a 25530325 sensor shouldn't set you back more than thutty bucks. Now if it were the *cam* magnet...

he did say the magnet is gone. good luck with that. how much you willing to spend? you would basically be changing a timing chain. in fact, you might as well do that while you are in there. the magnet is like $10, but it was like $150 for the whole job and 3 days in the neighbor'* garage. hope this helps. btw, me and my dad did it ourselves.

Padgett is trying to point you to go here www.6007.us for a step by step description on what you need to do to replace the cam magnet and sensor. Pictures too(woo-hoo).
Go to Automotive Technical Notes and then Simple Cam Magnet replacement on a 3800 Even I did this job last year. One of the most satisfying jobs I did to see the Check Engine light to go out!!!

Original post said CRANK not CAM magnet so I responded that way. Have seen both go missing. With a missing CRANK magnet, the car will probably not start. With a missing CAM magnet, it will start but give a code 41.

Well my parents took my car to the dealership....im at school so i have no way of getting it there, and the dealership told my parents that the Crank sensor was damaged and a magnet was missing...i only ran the diagnostic and found that the Crank sensor was damaged but they found out the magnet was missing...either my parents didnt listen right or they meant crank sensor

But i guess its not the crank magnet cause the car starts fine...when its warm out...but when its cold, the car takes round 5-10 minutes to start up because it will sputter and ill have to turn it off and try again.

But i guess its not too bad? lol...well thanks for the help guys...i really appreciate it...im just trying to get this car in good working order so it becomes more reliable than it is

also, one more thing, the dealership refused to do work on the car since its so old because apparently the problem is inside the engine so they were afraid of taking on the liability of breaking the seals on the car. sooooooooo if that makes any difference id appreciate the input.

Translation, they don't have any competent mechanics. What a moron! I would steer clear of this stealership!!!

Well still sounds a bit confused, usually the magnet is gone and the sensor is good (unless the dealer did not put the sensor back on after checking for the magnet). See my web page for what both look like.

Engine SEALS ?! Is this a LADA or YUGO dealer ? Certainly not Buick.

Taking a long time to start when cold sounds more like a fuel issue, possibly the relay (cranks til oil pressure comes up, then starts)
