egr mil light

[lofty531135]

Hi.

I have a 2009 mk7 Transit with 180000 on the clock, it is a T300.

The van runs fine but I have an mot coming up in March so need to get it sorted.

A few months ago my mil light came on and when I read the codes it was egr valve fault, it has water cooling, I replaced the egr valve and about 2 weeks later the mil light returned.

The error codes are P1402, P1103.

I disconnected the egr valve connector and put a black multi meter wire on the earth of the van body and with the ignition on but engine not running I put the red probe on the number 1 wire of the egr connector which is supposed to be 12v, there was no voltage so i tried the rest of the wires and no 12v, forgot to say that I get 4.9v on the number 4 wire.

My question is does anyone know if there is a fuse for the power to the egr valve and if so could somebody please tell me, I have been searching about a month online and I have looked through the handbook for the fuse identification but there is nothing related to the egr.

Cheers.
Ian.

The EGR is controlled by the PCM...the P1103 code is a MAF sensor out of range fault...pretty common in conjunction with EGR faults.

I'd be checking the loom for the EGR first, check for continuity/breaks etc...

+1 for broken wire as very common, done mine couple of weeks back

Hi Guys.

Thanks for replying, are you saying go back to the pcm to check for breaks because I do not know where the wires connect to in the pcm.

Cheers.

A lot will depend on if there is a break... and where it is. You may have to go all the way back to the PCM though...Just follow the wire colours from EGR plug/connector to PCM, just check to see if you have continuity from one end to the other.

I went back to the connector on the pcm and i put a wire piercing probe on one of the 5 wires and I removed the multi plug on the egr valve and probed that paticular connection and tested each wire this way and there are no breaks in any wire, they made a continuity signal.

I then tested pin 1 which is to supply the 12v for the motor and the reading was 1.16v.

Cheers.

Maybe a faulty ( new ) EGR, especially if its a pattern unit. It's not unheard of.

[lofty531135]

It isn't a ford part, Shouldn't I be getting a 12v feed from the ecu to open and close the motor.

Ok. Never needed to test the feeds myself as usually the valve itself is the culprit. I have a spare i plug in temporarily.

I believe its a PWM signal that modulates the motor so not a solid constant voltage.

[lofty531135]

ok, thnx, Can you recommend a company where I can buy a new Egr valve from please.

Did I say something wrong.

Just go for the cheapest one of the right type on ebay , They are all much of a muchness quality wise.

If you like you can bypass the water cooling if you fancy with a piece of pipe and some hose clips as the water cooled pattern ones are no more reliable than non water cooled. Non water cooled ones may be cheaper.

if going down that route just get it deleted completely
