Welcome to the forum. The diagnostic test is fairly easy on the mk1, all you need is an LED and a bent paper clip. Then you have to count the flashes, there is a good guide on the mx5.co.nz site.

The CAS is a bitch to change, about as inacessible as you can get.

Hi Sally,

As Lewis said, this really should not be a problem as the OBD port on the car is an industry standard device common to all cars of this age and newer.

Also the crank angle sensor or CAS as it is called is a pretty common part and Mazda, MX5Parts and a host of other places like Auto Link will supply them, the later two are mail order to your door. (or the garage)

My feeling is that I would try a different garage as any garage that has any knowledge of Mazda's should have no problem in this.

It is actually just fiddly to replace as well, not the devils own job, ever our own Mr Stanbury has done it.

I am sure there will be people who can tell you garages to go to, as Corby is not that close, but Corby Car Care and SR motors would all do this for you no problem and do a good job too.

hi many thanx for the replies,because work is mega busy[i guess id rather be busy then unemployed!]i have not had 5 mins to even reply.
my main problem is listening to 2 many people who have no idea on mx5's!if i remember i did do an led light test and if i remember id came up with code one,beacuse someone told me this form of testing is inacurate i wasnt sure if i could go by what it was telling me,code one i do think means the CAS?
i would have a go at changing myself but i really aint got a clue lol i was told to change the ignition amp as well,but i wouldnt have the 1st idea where to locate it let alone replace!
so if anybody can recomend a mechanic i would be very gratful,the car currently in standens barn but im working in oxford during the week i can get a mate to tow me as its been on his drive now approx 6 months and hes getting a bit fed up of seeing it lol.
can anyone help? many thanx.

thanx hotspa i did contact paragon few months back they put me in contact with there mobile mechanic who deals with elctrical problems,he disconnected the immboliser to see if that was the cause(it wasnt) but unfortunalty he didnt have the diagnostic plug adapator to plug the laptop into my car,kinda left me at square one really,except £50 lighter in the wallet!
im just wondering should i just get a new cas and find a mechanic to change it?secondly if i was to do this and it was the cause would i need to reset the ecu in anyway?ie disconnect the battery anf hold brake down for 20 seconds?)
many thanx for the replies!

I am down at Paragon tomorrow if you give them a ring and can get the car there I know they can sort it out for u . They have all the test kit there. Will pass on what happened and I am sure they will be accomodating as they r a great bunch of guys. ( Was lucky e nough to get a go in a Zonda....yes a Zonda that was in there last week for an mot!)

Hi Sally, I was at Paragon today and they were horrified that you had been lefft like this. They dont use that auto electrician now!
If you can get you car there they have promised me you will be looked after and the car will be sorted, after all they have built a reputation as one of the leading performance garages for japanese and american cars in the midlands and dont want anything spoiling their reputation.
Dont ring on wednesday as they are down in London doing some publicity filming for the latest fast and furious film.

hello again!
quick update i found a guy who took it away n done a diagnostic,turns out the imboliser was still interferring with the ignition and its defo the crank shaft sensor thats gone.
in case i havent mentioned the car is a jap import,the guy has looked all over the net and cant find an import crankshaft sensor for under £280,i really cannot afford this combined with the labour charge,but he would be willing to fit a second hand one if i can find one,if anyone would have any info on where i could pick up one for less then £280 then as always i would be very gratful!

Hi Sally,
From what you are saying you have a 1.6 and you need a new Cam Angle Sensor?

I have never heard that a Eunos will burn out a UK part and in fact I can not see firstly any reason why this sensor would be any different at all across the worl as it is just sending a position signal and secondly any electrac reason why it would cause anything to burn out.

If you want a new Mazda one I can supply a new genuine Mazda one for £200 including vat.

In fact I can supply most parts at a lower price and if people can pick them up it saves the delivery charge as well. :mrgreen:
