Technical Eml light, triangle

[Steveetee55]

Well after months of agro triangle eml, throttle relearns, new pedal and limp mode galore, culminating in one yesterday stuck in traffic , i think i've had my eureka moment, on checking continuity on the ecu small plug wires to the throttle body the multimeter was jumping all over the place when i wiggled the wires going in to it so its a bad connection in there was worth the price of some back probes but ran out of time for further inspection, so i think i'm in the ballpark at last..

I think this post could fit in the "What made you smile today" threat
Congrats on finding it!

As is so often the case… a ‘mechanical’ failure (loose wire, corroded contacts etc) seems (along with low battery health) to be the single biggest cause of fault codes and the engine warning light. Well done for finding it.

After a 500 miles drive back from France today, 3 miles from home the Triangle ! illuminated !! Stopped and restarted and it's gone away . I'll do a scan tomorow to see if anything is there.

Usually it shows a message on the digital display too (eg ‘Check number plate light’)… I believe the only time it doesn’t is if the earth to the oil pressure sensor (on a TwinAir) is comprised.

Mine came on and usual no stop start, no esc, no hill assist, and limp mode been doing it on and off for 3 months, i think i'm in the ball park which with electrics is 90% of the problem, for now i have cleaned up the connection and so far so good, as said my ebay 6.99 back probes are already starting to earn there keep, getting a new 115 fluke multimeter tomorrow my kewtech is on its way out, work are paying for it to replace my kewtech multimeter which is a bonus

What are the 6.99 back probs?

You can push the probe into the back of the connector plug without having to take the plug apart for test voltage, continuity etc, if you have a look on youtube you will get the general idea of what there used for

Yeap!, Triangle appeared again today and dash briefly showed "Check Number plate light" I was looking this time as it appeared, dodgy connectioni t's ok now again.

Change the bulbs. They don't need to be blown to throw a check engine warning, it can happen because they're weak.

The system looks for ‘the right resistance’ from the bulbs. A corroded contact or the wrong wattage bulb can show the error, as well as a blown bulb. Often just wiggling the bulb is enough to cure it.

Which is why when you put led bulbs in as i tried for stop/tail bulb it throws a code as led draws a low resistance, worked in my daylights tho

I'm getting the yellow triangle on my 2015 1.2 Easy. No error message is being displayed.

Looking at the manual, I've narrowed it down to

Fuel cut off system intervention/failure
Exterior light failure
Oil pressure sensor failure

The rear numberplate lights both don't seem to be working, so it may well be that, however I'm not getting an error message on the dashboard.
I notice that there are a lot of posts on here about oil pressure sensor issues (not earthing properly) but they seem to be on the TwinAir rather than the Easy.

Any thoughts?
If it's the fuel cut off, am I OK to keep driving it until I can get it fixed?

Many thanks

It will be those lights
if fuel cut off, the engine wouldn't run
And the 1.2 doesn't have that issue with the oil pressure sender.

The message 'check numberplate light' will probably have shown at some point but eventually it stops showing the message but still shows the triangle. By the way, driving with those lights failed (even in daylight) is 'an offence', technically, so they do need to be fixed. And certainly before next MOT as that will be a fail.

(If replacing the bulbs doesn't work, then it's likely the wiring into the boot line (in the rubber tube near the hinges) has cracked and broken)

These festoon type lamps are notorious for giving trouble in the number plate light holder
I replaced mine with LED to do away with the problem

Thanks for the help - quick trip to Halford's this morning sorted it (and one of the daytime running lights that failed this morning despite having been replaced on 22nd June!)

Those DRL's can be a PITA if they fall out inside the housing
