PROBLEM WITH SPARTAN

[f250 fx4 kid]

ok so i have the 210 in my truck cat/dpf delete pg7 intake ..and all has been great i was out in ohio and the day before returning to nj i decided to reloa my tune like I frequently do... Now the next day i started her up and everything was fine and i ran it for about 3 hours then it went from full "210" power to less than stock it was limiting me out at like 65-70... so i cycled the key and started her up and it ran fine for about 2-3 miles then it just ran slow again.. so then i said oh well ill load stock.. with it stock she ran good for a littel then it retarded itself AGAIN then cycled the key multiple times along the way to nj then one time after cycling the key it was fine running stock then just as i was pulling into my girlfrineds house it started to regen and blow white smoke so i cycled the key and poof it was fine .... so i loaded the tune and had the same problems run great for a few miles then limits it ...... and it i run it when i limits it it wll pick back up and have full power every once and a while now the codes are d specific ford P040D exhaust gas recirculation temp sensor A circuit high...... and P1000 obd systems readiness......... now when i clear the codes and cycle the key itll run fine for a few minutes then the codes come up and it is in a limp mode kindof ........ ANY HELP im guess some sensor is bad???.....

after looking at it today the only thing that i can think of is the sensor that screws into the dpf section of the delete pipe is broken cause it screws in but the grommet that slides over the top of it and connects it tot he little black box is broken so the sensor and the box are two seperate pieces, but it has been like this since i did the chip and all about 4,500 miles ago....

ok so from looking on the spartan forum and other forums i have found that it seems that the egr temp sensor goes bad when this happens so i just ordered a new sensor.... now how do i change the sensors and where is the sensor?

[sawtooth1]

did you ever find anything out on this?

[kwayne]

Does anybody have the Part Number for the sensor associated with this DTC?
Please post if you do.

So was this the tuners fault or just a sensor going bad?

You should have had to unscrew this sensor to install your DPF delete.

why would you constantly reload your tune? these trucks had adaptive strategies i thought, and learned over time? aren't you basically forcing it to keep learning

P040D sets when teh sensor in the RH up pipe from the manifold to the turbo isn't working properly.

I've changed a couple now. You need to pull the RH inner fender out to do it.

Also - this sensor would remain untouched installing a DPF delete.

I'm assuming you're referring to the beginning of his post where he said he was going to re-load his tune before heading out. That's a smart way to increase your trucks longevity IMHO. Spartan's 210 and + tunes are designed and marketed for RACE and TRACK use, where performance takes precedence over engine/tranny longevity.

I'm not saying that running the more extreme tunes is necessarily "damaging" to your truck, I know a lot of people have run the 210 and/or 310 for ~30,000 miles without any immediately perceivable trouble, but to even imply you can run equally as long with a tune compared to someone with a stock setup is ridiculous.

What we really need is a tune that you can activate "on the fly" so it's not so hard to return to stock and you can only activate the extra power when you really need it.
