Fire that mechanic. You need that sensor for your engine has to monitor EGTs to prevent piston melt. Cummins sees that and kiss warranty goodbye. You don't want that with a new turbo. That sensor helps control fuel flow. If EGTs are too high, fuel flow drops some to lower combustion heat. Yes the sensor is pricey, almost $150, but it's really important.
gregor Thanks this. -

hi, yes thats 06' volvo vn, and this is sensor right after turbo on exhaust pipe (under air filter assembly close to firewall ) , Shaggy76 you saying i need this sensor its relly important?!?!?! this is the same answer from my two friends also volvo/cummins owners i called at night, i did 400 miles on new turbo and thing i see on dash gauge that turbo is kicking fatser (response) then old one which probably will hurt my mpg?!?!?! even when parked and little tap on throttle (to 700-900 rpm) and boost will rise little bit, i havent that on old turbo

I would recommend you buy aftermarket pyro and learn how to use it - Teltek makes nice oneLast edited: Dec 27, 2012
t800kwopper Thanks this. -
ok since i put new turbo i did about 4000 miles, truck pulls realy good, mpg is good as well , still can see in my right mirror blow outs from exhaust shifting gears, when taking off hard with 40k + load or going uphill can hear horrible noise shhhhzzzzzzzzzzz on full about 31 psi boost?????? no air leaks, no higher colant temp been found, oil temp betwen 209-225, egr unpluged......mechanic says also without gas temp sensor it wont mees up if my egr is unpluged or breaks down on the road ??? in his opinion i will have to keep egr in working order all the time ( spending money) if that sensor is mounted, deal with higher coolant temp. and have lower mpg etc. ....still i dont know if i should spend another $$ to put that sensor ??? my engine has 1,120.000 miles no overhaoul, no crankshaft bearings been changed, recently did oil sample which looks very good....any ideas??

in the meantime , unplug it correctly. Wait until engine is cold , turn the key to ON , but don't start the engine. Walk around to the EGR , and unplug. You're now good to go. -
ok thank you guys , im consider to do that....but do you think no gas temp. sensor or improper turbo mountage or wrong egr unplug cousing that strange sound???
-
by the way where to do egr delete and how much $$$$ , anyone did it already ,if so please share poistives and negatives
