Possible crank sensor issue?

Hi I recenty purchased a fiat doblo 03 70,000 miles and have been having a few issues. The symptoms i have are

Struggling to start in the morning
Engine cuts out randomly then starts no problem minutes later.
Engine shudders at certain speeds
High revs in first gear without much speed pulling away.
Revs continue to rise during gear change.

Could it be a faulty crank sensor or i am i missing something? Im just going on what ive read on google.

Thanks!

Re: Possible crank sensor issue?

What engine mate?

Have you got, or do you know of anyone that can hook it up to an OBD for you and see if it chucks any codes out?

If you haven't yet, it's probably the first accessory you should buy for your Doblo - they cost peanuts on eBay and the software is free.

Copy and paste this into eBay: Super Mini ELM 327 V1.5 Bluetooth OBD-II OBD2 Car Diagnostic Interface Scanner. You should end up looking at a black box with purple and orange on it called ELM327. from China it will be cheap but slow, from Europe more expensive but quicker. Worth looking at a second hand one.
I wouldn't recommend any other type - this one is known to work, others are known to give problems.
There is a USB version if you don't have a laptop with Bluetooth, but the Bluetooth you can use with a mobile app and monitor via your mobile as well.

The software: http://www.multiecuscan.net/

Some of what you describe *could* be a crank sensor - if you've got one you can swap out (perhaps a mate has the same engine) then great, have a go. But it could be that or other things, or a combination of things.
Really, it's better to start with the OBD and work from there. By the time you've eliminated all the maybe's it would have arrived and you'd have a read out to work with.

Re: Possible crank sensor issue?

Its a 1.9 diesel, would that still work? Sounds like a good route to go down. Appreciate the help.

Re: Possible crank sensor issue?

hi , I have a 04 doblo 1.9 jtd , had it from new , had to replace the crank sensor last year , it would cut out at the same place on the way home when it got warm !! also the earth lead from the battery bolts onto the inner wing and to the gearbox corroded on the gearbox end caused starting problems ( the cable looked like new but was corroded under the insulation and snapped , I replaced the starter motor before finding it &#128545egr valve sticking too .

Yep. Plugs in behind the fuse box cover in the cab, down the bottom under the fuses.

Spot on. The first thing that needs checking for just about everything. Mine lloked perfect, but the cable was just sitting in the cup of the connector, so it was pot luck whether it started or not. So, anyway, after I'd taken the starter motor off and put it back on... I checked it properly

Hi,

the crank sensor itself doesn't typically leave a fault code - so awkward to diagnose..,
but it's worth getting the codes read to make sure it's nothing else

Re: Possible crank sensor issue?

Thanks for the tip, i've ordered a new crank sensor as well as the scanner. Driving to work today and cut out 3 times, on way home it was fine. One thing I have noticed is that on the 4 seperate occasions its cut out, it wasnt raining. Never had a peoblem with it cutting out when its been raining which makes me think its keeping somethinf cooled down?.... Maybe just a coincidence.

True dat... with any motor these days, I think its prudent to keep an eye out for a cheap second hand one on fleabay, test it and then keep it on-board, a bit like a spare wheel.

Had the crank sensor replaced and so far so good. Its nice not breaking down 4 times to and from work every day 😁 going to put the scanner to use tonight to try sort out the other problems.
