This has been happening since yesterday.
I'm driving along quite happily, but when I slow down to stop and dip the clutch the EML/orange engine symbol on the dash comes on, and then a second later the engine cuts out. I turn the ignition off and on again and carry on driving. This just happened 3-4 times on a 10 minute drive to work!

It seems like the EML stays off as long as I keep the revs going.

I don't know if it's related but the speedo and mile counter have also stopped working

Any help/tips much appreciated.
Car is a Corsa B, 1.4i, X14XE engine.

I did a bit of reading round the 'symptoms' I'm getting.
I checked the cigarette lighter was not being shorted...nothing is touching it.
I checked fuse no.18 (the 20A fuse)...it is sound.

Will the 'paper-clip' test work on my engine?
If so, what pins would I need to bridge?

Yeah, try the paper clip test.

Heyyy, thanks for the link!
I just went out and did the paperclip test.
I got codes "19" and "24".

I looked them up and:

19 = Crank Angle Sensor (CAS) - Incorrect RPM signal
24 = Vehicle Speed Sensor (VSS) - No speed signal or low voltage

With the symptoms I described in the earlier posts does it look like I'll have to replace BOTH sensors?
Are they both easy to see from the bottom of the car?

Fix the speedo and it will solve all of your problems. X14xe b will be a normal mechanical cable iirc.

Thanks for the reply. I was reading round the topic earlier and people were saying depending on what type of speedo you have that will determine where the 'sensor' is.

People were talking about electrical clocks and mechanical clocks. I'm not too hot on this topic, but my speedo is not one of those LED display types. My speedo has physically rotating numbers like an old gas meter. So does this mean my speedo is one of those 'mechanical' ones?
And if so (after reading around) does this mean I won't have a speed sensor on the gearbox, but rather I'll have a sensor within the clocks themselves - so to fix the problem I just need to change my clocks?
Or something else?

Thanks.

It sounds like the crank sensor as the test showed up. I had the same a few years ago. IIRC the crank sensor is on the back of the block at the opposite the water pump outlet.

What year is your car? Later ones have electric clocks, sometimes the fuse goues so check them too.

Also if you look down on top of the gearbox you should be able to see if its either a wire or cable going into the top of the box.

Mine's an N-reg...so I suppose it's 1995.

I reckon it will be cable driven but its best to check on the gearbox.

Not 100% sure on this but I think cable driven speedo's start at 10mph and electric at 0mph

My car was at my mechanics today for a routine service so I asked him to check my speedo cable.
He said it was all twisted up but he couldn't tell if it was damaged at the clock end because he didn't take anything apart.

He said he charge an hours labour plus parts to see to it.

Is it an easy job for a newbie like me?
(It could be whole cable? Or just the connection at the clocks? I dunno).

Its pretty easy. It's better to replace it. Theres a few threads come up on google how to change it.

Basically removed clocks to disconnect it from the rear of them, disconnect it from speedo drive on the gearbox. Feed new one in the path the old one went.
