The infamous EGR valve problem

[E27006]

This is the location of the EGR valve:



The EGR valve itself:

The EGR valve has an internal electrical component called a potentiometer,  the potentiometer  operates  by the movement of the EGR valve stem and a signal is monitored by the ECU to determine if the valve is in the open or closed position.

The potentiometer wears due to movement of the EGR valve stem.  when it wears it will give an erratic signal, this bothers the ECU and the car bucks and jumps.

If you suspect the EGR valve may be the cause of problems on your engine (particularly rough running / cutting out at low revs) try making a temporary metal gasket (a piece of tinplate or aluminium or any thin metal really) to fit underneath the EGR valve and effectively block off the passageway.

The only thing it will affect are the emissions at higher revs - the valve should be firmly closed at lower revs anyway.  If the engine runs smoothly with the gasket in place then it points to EGR valve being the problem - if it makes no difference then go to plan B, (plan B is normally to admit defeat and to take it in to a dealer.)  Don't be tempted to leave the gasket in place for too long - it is only meant as at diagnostic aid - not a permanent fix.

I'm new to this , but heregoes.

I'm having this problem and it has been diagnosed by a main dealer, at a cost of £57-50 I might add.
What I would like to know is where can I buy an EGR valve, how much does it cost, is it a DIY job or is there a complex setting up procedure?

Regards,

The EGR valve is available from honda but an independent might do it. I would try both to compare prices and then go from there.

Its an easy diy job to change. As you can see from the pictures in the other posts,its just a case of removing the electrical connection on top and then undoing the two securing bolts that hold the EGR valve to the engine. Refitting is just the reverse.

  Try clicking onto "Emission Controls.co.uk" they offer EGR valves. I have not checked prices.

Hi All:

I have a 2002 1.3 Jazz with 57000Km's on the clock. My wife advised me when we first bought it several months ago that it sometimes chugged when cruising or slowing down...
I took it for a fast country run and it sort of came right.  Last week she advised me it had got worse.
So today, I removed the EGR Valve, cleaned it with CRC, Kerosene and contact cleaner, plus gave it a few good bangs on the work bench. You could feel the solenoid moving etc. Refitted EGR Valve and car has not driven so well since we bought it...  I suspect the banging on the bench may of freed up the solenoid..., as otherwise it was not that dirty.... Car is now 100% better....

I`ve emailed them and their answer is: "Sorry we cannot help you with this part Honda dealer only".

Anyway I`ve checked the EGR valve, it looks clean and I can move the stem.
My car has 45500 miles, 52 reg, mainly driven in London.
I`ve appointment at Honda Chiswick on Friday. I`ll post the result. To check my car will be about £34.00.

Mod.
I think I`ve fixed my problem accidentally.
I took out the EGR valve, had a look in my hand, it looked clean. I pulled out the stem with the screwdriver, but the stem`s shoulder is so small the stem jumped back to its original place. I`ve repeated this about 3-4 times and fitted back.
The next day I haven`t noticed any changes but a day after I did!
My engine runs OK!
The thing what I did was the stem jumped back and the dust from the top of the stem (up inside) fallen off, so it "cleaned" itself.
I`ve cancelled my appointment with Honda.

I hope my story helps you guys.

Our 2003 CVT simply refused to start on occasions. The engine turned over, even when warm/hot without problem, but would simply not start. The snag was highly intermittant- if engine was allowed to "cool" the fault seemed to solve itself. ALL lights on the dashboard came on normally every time.
It was surmised it was the EGR valve- and I see other posts which offer this as the source of the problem
The car was sent for service- I was gob-smacked to be advised the fault was the IGNITION key! How so I wondered- and still do!
Nonetheless, it is easy to try the original faulty key and one is immediately plagued  by intermittant hot start problems. Changing to the spare key solves the snag every time.
I can offer no explanation as once the barrel of the ignition lock turns, as one starts the engine, one would have thought, the actual key used was working properly. I can only report that changing to what had been the "spare" key, solved the problem!

That would be due to the immobiliser. If the transponder in the key doesn't respond reliably, the immobiliser will kick in.

Hi

I've got a 2002/3 1.4 Jazz which I bought second-hand which I love. But it's just developed the infamous EGR judder.

The Honda dealership have quoted me £410 to replace the EGR valve. Over half of that is the cost of the part.

However, I can get the part myself for £77, and the fitting of it seems to be 'relatively' simple -- for a qualified mechanic.

My question is: is there any reason I need to get this done at the Honda dealership? Is there any special computer stuff that they need to run, or (now that it's been diagnosed) is it just a simple mechanical swap out?

I should just add I don't have any kind of warranty. Any comments gratefully appreciated.

Thank you

I don't see any reason to get it done at a Honda dealer or any garage for that matter.

If you are OK with a spanner then its just a simple swap.

There is thread on this forum with pictures if that helps.

You can do it home, as JazzyB wrote. Get the spanner and swap.

Eazy-peezy - just a couple of 13mm A/F hex bolts and an electrical plug.

It will help if you have a 1/4" or 3/8" drive socket set with a 150mm extension.

my jazz has 131000km.i solved my egr problem today with some carb cleaner.the car runs so much better than before.

[Jazz-E]

Narcis, how did you solve the problem?
