A pipe came loose from the back of the plenum and the Engine Management Light came on.  Fixed the pipe, but the light is remaining on.

What do you think is wrong?  Will the light go out eventually?

How to fix please?

Needs a code reader to check the code, and reset if it related to the loose hose. Your 3.2 is OBD compliant, so any basic tool ought to work.

[Doctor Gollum]

Which pipe or hose? I ask as that may have a bearing on why the light came on.

Notwithstanding how it came off to begin with

Yes, sorry I didn't make that clear, it is one of the four breather hoses into the rear of the plenum.  It is one of the two smallest pipes inside the other larger ones.

Either the purge valve to intake vent hose or smaller crankcase breather hose.

No reason for that to just fall off unless the hose has degraded or it wasn't refitted correctly.

All four left the factory with crimp clamps fitted.

And the pedal trick will tell you what the code is.

Very rare to see one with any of the clamps still fitted though, as the hoses are a pretty tight fit anyway.

Hence asking how it came to be detached

This hose became further split at the end when last fitted by me, and there was no clamp.  Serek had to take these off when doing the cam belt last week, and, no fault on his part, the hose split a little further when refitting, but lasted until today when it started to leak.  Have refitted with a jubilee clip, but the Light remains on.

When I do the major service later this year, I will replace this hose.

I'd be surprised if any of the pipes on the back of that breather can cause the EML light to come on. ECU only knows what the various sensors tell it, and AFAIK nothing measures anything in the breathers.

More likely to be an electrical connection off one of the various sensors, actuators or valves that are part of the plenium. The ECU does know if they're unplugged - it basically measures their resistance, and if that resistance is out of limits then EML on. As others say - get the codes read, or do the pedal trick.

Pedal test trick to get the code?

It's unmetered air into the intake which potentially causes discrepancies elsewhere, hence the light.

How do you know I absolutely love roses?
