View Full Version : Possibly crank angle sensor?

Did a bit of a search but I just want some clarification.

Went to the shops yesterday, car was running beautifully (keep in mind I had the car serviced last Wednesday - 90k service, timing belt was done) Came back to the car and it turned over but wouldn't start. RACQ guy said there's no ignition pulse or spark.

Does this sound like a crank angle sensor? If so how much is one? Is it possible the mechanic stuffed something up when he installed the timing belt or would I have noticed something gone wrong sooner? (been driving the car for a week...)

Any other possible explanations? Immobiliser? (standard mitsi one)

Cheers.

crank angle sensors are moulded into the lower case cover - they're about $200 including the cover, add another $25 for the spinning disk that activates it. Plus a barrow full of labour to get the thing replaced!

This could be your problem if it was interfered with during the belt change - methink the two are related and you should go back to where the belt was done and 'have a few words' as such!

It's back where it got done and the mechanic who did the work assures me it was not caused by his work. They'll have a look at it tomorrow and tell me what's wrong.

U know my car did the same thing about a week ago, I thought it was the fuel pump, it's working fine now. It's got me baffled....

Edit: Immobiliser was mentioned to me to, I had no error codes though.

Did yours just start again? Because I had mine towed to the mechanic and it didn't start in the hour or so from the first time it wouldn't start...

Sounds like it could be the immobiliser - I had similar issues (http://martybugs.net/articles/magna-stall.cgi).

Not really the same thing. Mine didn't even start to then stall, just turns over but no ignition.

my 97 TE does the same thing occasionally. Dad and i got his fluke (yes i know, bad name) multimeter into it in Newcastle one night, it seemed the injectors werent getting any pulse, but was intermittent. We put it down to the fact that it was raining, and some moisture could have gotten into the plugs. Spoke to the guys at my local mitsu place, and he said it is common for the magaganas.
Sorry bout spelling, have had beer, but i still speak the truth,

Well, it was the crank angle sensor. $187 for the part trade price from Mitsu, then probably $300 labour. :cry:

Hmmm - any clue as to why the existing one failed?

None. I did think it was faulty workmanship, but wouldn't the part fail immediately after the timing belt was done? And not a week and a few hundred kms later?

not necessarily - they apparently can get dislodged during servicing and then they get abraded from contact with other parts - causing a failure after some time. It'll be interesting to see the part back after the service.

Well, turns out it wasn't the crank angle sensor afterall but it's returning crank angle sensor errors. Mechanic thinks it might be the crank angle sensor in the distributor? (wasn't listening too well) Hopefully I can take the unwanted part back... Find out Monday now... :confused:

mine was doin wat u described. very annoying. but then it would just work :nuts: like after about an hour.

i had a few different problems that sorted it out. there was a split in the rubber that the fuel pump connects to, my fuel reg had died and last time it was the distributor which was replaced with coil pack neways :cool:

Well my car is still at the mechanics. They're having a hard timing figuring out what's wrong with it. They think it's possible that it might be the ECU - Anyone know or wanna guess what a new Ralliart ECU would cost?

i know there is a spare one sitting in the wreckers i got my engine from unless they sold it already caz i didnt get it sent with the engine

It spins me out how most mechanics jump straight to the ecu. I really hope they do some preliminary checks of other sensors before jumping straight to the ecu. First up if they have the equipment they need to extract the codes from the ecu if possible that may point them in the right direction. You did mention it's returning crank angle sensor errors. Could it be dodgy wiring in the area. Did they plug it in. If they have no idea try and get the car back and worst case scenario get it to a dealer.
If they do replace the ecu and problem persists i wonder who will pay for the ecu. Will he be able to return the ecu and get his moneys back. These questions need to be asked otherwise you could be up for a bit of cash when they do fix it and they may just blame an unrelated part and you will have to pay for it.

Sorry for been critical but there are many mechanics out there that are not equiped or familiar with some of the efi systems in later model cars and tend to rip off customers by experementing swapping parts till they find the culprit.

They've had the car 3 days now. The ECU is now pretty much the last thing they're looking at. The reason they're looking at it they told me is because it's returning crank angle sensor errors but there doesn't seem to be anything wrong with the crank angle sensor (or something like that) So they're trying to find out why it's returning errors on parts that are fine. Also then there's the combined headache of the Haltech I've had installed... dunno how that's gonna fit into it all... plus then I'm really worried about how much labour I'm gonna be charged this being the 4th day they've had the car. I have a lot of savings money for this very reason so the cost doesn't worry me too much (I hope to god it's not more than a thousand bucks) It's just a headache I don't need atm my car being off the road. :rant: :cry:

UPDATE:

After being at the mechanics for 9 days I finally have my car back. It turned out to be the Haltech Interceptor piggyback that was causing all the problems. They unwired it, wired my standard ECU back in and she's now running like new again. Thank god. In the end they ended up working on my car for a long time - they charged me $693 all up to fix it after having it so long which i was very thankful for.

Now I have to get the warranty sorted on the Haltech, either get my money back or a new unit. If I get a new unit it's gonna be going up for sale so stay tuned.
