Switch off EGR for $1

[Mavman]

Hi All,

Righto, first post.

Quick tech tip. I've switched off my EGR for less than $1 on my NW.

Instructions:

1. Buy 3.6k Ohm resistor (0.5W or greater),
2. Peel back tape to open up conduit on MAF sensor wiring,
3. Cut blue-black wire on from MAF sensor,
4. Put some heat shrink on each end of the cut wire,
5. Solder in resistor,
6. Heat the heat shrink,
7. Re-cover with conduit, and re-run black tape.

Well hidden, looks professional, cheap, and it works. Resistors come in a pack of eight; eight for $1.

To check that your mod works, program the EGR into your scan gauge:
TXD 07E0012C
RXF 0441052C0000
RXD 2808
MTH 006400FF0000
name EGR


I've attached a resistance vs temperature chart if you want pick a different resistor size. The 3.6k ohm resistor is enough to switch it off on a 40-45 degree day. Go for more resistance if you live in the top end.

The intake air temp on the scangauge uses a different sensor so you don't lose that functionality with this mod.

I installed the mod a couple of months ago. No codes thrown yet, nothing negative noticed.

Cheers,

Grant

Good job. Hard to pick and the heat shrink will definitely help keep the integrity of the join..

I put a 4.7k resistor on my parents 2009 paj and it stays closed in 45+degC

I did this mod about 3 months ago, no problems so far.
I used the 4.7

Awesome Mavman! Is that resistor just a Jaycar special? Looks so simple. Might just go with that I reckon. Thanks heaps for the detailed post. I've been procrastinating with the plug and play thing for ages. Wanting to get it but not wanting to shell out the $$$ for it, thinking of blanking plates. But that's it $1,! And so simple to do. Gonna get me a resistor on my next days off.
Thanks

No probs Discog,

Any hobbyist electronics store will have the resistors (eg Dick Smith, Leading Edge Electronics etc). If you can't get 0.5W, just go for a larger wattage. Likewise, if no 3.6k ohm resistors available, just go the next size up (larger number). Resistors will be labelled 3K6, which means 3.6kohm.

Cheers

gee thats a lot cheaper than $150

Got some at Jaycar today for 55c for 8 of them. Got 3.6 & 4.7 ohm. Might try 4.7 first tonight

hi guys have a look at what we did to challengers with this mod been going for almost 12 months here is the link ..regards john

Can I assume that the resistor mod would be the same on the NX??

[Hatto]

I am thinking of cutting the wire and putting bullet connectors on each side of the cut (to make the mod removable) and solder a short wire to each end of the resistor with a bullet connector on each end of those wires. This will make a removable resistor mod. That way I can try both the 3.6 & 4.7k resistor to compare the two with the torque app.

Hi all

I recently installed a 3.9 k resistor to close the EGR and since then, my ultragauge has continually shown the valve closed. An upside is that I have noticed an improvement in fuel economy around town driving of around .6 litres /100 km's as per the dash readout. Interestingly this is what I reckon I lost when changing to AT tyres and ARB Bullbar, so placebo or not I am happy. This tank of fuel is running at 10.6 litres / 100 k's after 650 k's and for the last year after lift and tyres I have not been able to get below 11.3 litres / 100k's for the same driving conditions. Time will tell I guess.

Rooster, how are monitoring EGR on ure ultragauge? I had a quick play on mine but could only get the EGR flow I think it was?

[Hatto]

Job done. Can't wait to see the results tomorrow. EGR is reading 0 on torque app now. Woohoo! Just drove it down the road a hundred or so meters and there was a noticeable difference. No turbo lag. Will see what tomorrow brings. This is what I made up as described in my previous post.
Now I can understand plug it if I need to.

I used bullet connectors as well, that way I can remove when taking it in for a svc if needed
