Anyone recognise what fault this dashboard warning light refers to?

[dobbslc]

As an example of the confusion these lights cause I had the following lights flashing on my Mitsubishi Outlander.
ABS, SRS, 4X4, plus the EML.
So no working ABS, Traction control, or 4 wheel drive!
The code reader picked up a code that said it was a problem with the fuel pressure regulator, I obviously ignored that and thought it was one of the ABS sensors as what has fuel pressure got to do with the ABS etc?
After a few hours testing the ABS sensors I found no faults so reluctantly ordered a fuel pressure regulator for £60 fitted it and cleared the codes and hey presto it worked perfectly!
I did a bit of research on how this system works and basically the engine management system needs to know the fuel pressure so it can operate the various other systems ie cutting the power when the traction control kicks in, if it doesn't know how much fuel is going through it how can it modulate the power? it's all interlinked!
It ran better and had better MPG too so I think this regulator was on the way out for a while.

On a car I acquired recently I’ve had two check engine lights: the first had no symptoms and was a faulty lambda sensor after the catalytic converter: the second was accompanied by terrible misfiring and vehicle recovery. It was fixed by ignition coil pack replacement. So you can go from one extreme to the other with one light.

one is directly related to the other. misfire, there is unburned fuel being pushed into the cat, This then screws the cat up. I had two coil packs on my 03 focus and a cat. didn't bother changing it second time. Engine light stayed on for about 6 years!

The EML comes on very regularly on my Ranger. It just means a 120 mile round trip for me

I may have been known to wire such offending lamps to the oil light, back in the day

But on a 2006 Toyota Corolla - you may well be looking at a long term fueling "cat aging" error code. Or equally painful O2 sensor/heater faults. And if you want to get the light off - you need dealer parts to do it - on this age of Toyota.

Best result here - would be a simple misfire. But the OP is not reporting any running issues.

You might struggle to get a garage to embrace this job - after doing a simple scan - error code read.

DIY might be your only option - due to the age/value of the car and the availibility of parts.

that made me smile

Good find,Thank you.

Probably a coincidence, the car had been for MOT 2 days previous. Then the light appears. I've had the car since 2012. I do less than 3k miles per year.

Might not be that bad of a fault - if it passed the gas test 2 days previous.

Actually the lambda issue was a failed heater element in the sensor that occurred months before the misfire so they weren’t.

I was communicating with an E bay seller regarding a plug in code reader device. He asked me for the VIN details to make sure he had the type that was compatible with my car. He advised the Ancel TD 100, but he did not have one in stock and could not get me one.

I have not been able to source that one, but I was willing to take a punt. Nothing ventured nothing gained.

a little example of what you can see with a reasonable diagnostic kit.
this was a historic code in the ecm memory.

Try disconecting the battery for five minutes and reconnecting it.
