Crank Sensor

Last week while driving my 91 Dodge Grand Caravan just stalled out on me,so I coasted to the side of the road and with several attempts it started.So I drove on about a mile or two and it stalled again at the light.This time it took about another minute and it started again.I went about another mile or so same thing,now its starting to rain so I'm trying to get to some shelter and again it stalls out but this time it would not turn over.I called my roadside service and tow truck driver shows up and saids it sounds like timing belt.

I had it towed to a Chrysler/Dodge dealership and 4 days later with me going up there to investigate to see why I haven't received a phone call,the service manager says it seems to be "the crank sensor"?What is this and what should I expect the repair cost to be parts/labor?Upon calling numerous times and getting no response,the service manager told me the mechanic had to replace my brand new battery (3 months) because for some reason the cars computer was erased when I replaced the battery and the mechanic could not get a diagnostics read and this is why it was taking them so long to tell me.I never knew changing your cars battery and alternator cleared your cars computer,done it lots of times and haven't had a problem.

disconnecting or replaceing the battery will clear codes not erase the computer it will give a code of power lose with in the last 50 starts i belive it is for dodge ask to see your old battery and have it load tested anything below 9 volts its due for replacement
as for the crank sensor it could be causing the trouble if signal is lost the computer would think it was shut down/key off
the part itself is around 50-80 $$
and labour should be about or less than 1hr
then diagnostic fee ??? shop decision/set fee

Chrysler can give you a free estimate on repair after the diagnostic (I believe they charge $75 for an OBDI). The Chrysler here's labor runs around $85 an hour. So with what Osborste gave you for the part cost ($50-80), labor and diagnostic, you're looking at around $210-$240 for repair, if indeed it only takes an hour to change out.

I'm still confused as to why they said they had to replace your new battery with another new battery because when you switched it out, the computer erased? Common sense would tell me if you replaced the battery again, the computer would erase again (until the drive cycles completed), right?

Thanks for the replys fellas,for some reason this dealership is taking a long time to fix or just tell me what is going on,after the service manager told me this about the battery having to be replaced I went up to the service bay where the hood was up and saw that they did not replace the battery like he stated,so I'm wondering does he know what is really going on with the mechanic that is working on my van.I have to keep calling to see what is going on everyday and he saids the same thing" the mechanic is looking at it right now".Is he looking at it or working on it I would like to know.Now people are telling me the horrow stories about this dealership and how they do showdy work and half ass work.Its almost a week since it was towed to them.
The last few days every time I go past the bay,no one is working on cars and this is a large bay,about a 20 car bay,so I'm wondering if they have the man power to service all those cars?By the way,this dealership is Darcars Chrysler/Dodge/Jeep in Marlowe Heights,MD.

this really sucks this type of service is how mechanics get a bad rep i would call them and tell the to fix it now or your taking it else where you need you vehicle back the unfortunate thing here is you may have to pay a service fee plus a tow to another garage if its just the sensor it should have been done that day its not weeks worth of work to replace it


my thoughts good luck

Update-I recieved a call from the service manager and the mechanic yesterday.The mechanic says he cannot find anything wrong with my van,he test drove it and it cut off on him Monday but it started right up and brought it back to the dealership and put it on diagnostics and still no trouble code and no check engine light.So he gave me a altermadum,either he could keep my van for one more day or I can pick it up,so I picked it up and paid the $98.00 diagnostic charge.He saids maybe the crank sensor is going bad but the computer is not showing any bad code for it and didn't want to put one in and it still continues to cut.I picked it up and drove it for a hour and it did not cut off.But I called a buddy up to see if I could bring it over to change the oil in his garage and on the way to his house it stalled coming off a ramp minutes to his house but it started right up and didn't cut off.On the way home about a couple of hours later while driving about 60mph I felt the van jerking hard a couple of times like it wanted to kunk out but it stayed on,so I went to a gas station and filled up with Mobil premium.Maybe its some bad gas or something,who knows.But if it continues I will take it to a specialist.One thing I wanted to know,I see he did not disconnect the battery after all,If I disconnect the positive for a minute or so and reconnect, can that clear the computer of maybe a bad code that could be causing it do what it is doing?Or just leave alone?

It more than likley wont stop it from doing what its doing. Disconnecting the battery would just make your check engine light go off, and clear the history code

And if the problem still exists, the check engine light will just come right back on after the failed drive cycle (atleast it should).

Well update fellas,my van broke down the very next day after picking it up from the dealer,two blocks from my job.So I had it towed to a Shell station next door to my job that works on our fleet of company trucks.Mechanic observed my van was losing spark immediately.They kept my van overnight and diagnosed a bad crank sensor and another relay,replaced both and I'm back on the road.Charge was $564.00 altogether parts & labor,but thats better than what the dealership did.Its a shame I had to take it to a gas station after taking it to the people that made this model.Should I go back to the dealership and demand my $98.00 for the diagnostic fee they charged me since something was wrong and they didn't diagnose it as well as repair my vehicle?

..but would it restart this time? it's much easier to diagnose something once it fails for good, and i don't think a failing (or failed) crank sensor will set a code. if it died for good before the gas station got to it, that would make it much easier to diagnose...

I have the same problem

It seems that my '96 Grand Caravan has the same problem, it shows all symptons you said. You mentioned in your post that your van finally got fixed by replacing crank sensor and one relay. Someone already told me about the sensor, but what other relay was replaced in your van? Do you know?

Thanks !!!

these crank sensors can be a pain when they go bad, when mine went bad on my 92 buick it didnt trigger a code in the computer either (even though I think it should) so after big bucks the second mechanic finally figured it out. Runs wonderfully every since it was replaced.
