I left mine plugged in, with the FCV motor broken and the butterfly pulled. I'm not certain what the lightning bolt icon on your dash was, I can't say I ever got that with mine. At the same time, I never saw any difference in operation with the thing plugged in or unplugged, just a code when the computer decided it wasn't happy.
I'd leave it plugged in and go from there. At the same time, the weird electronic behavior was most likely due to the extreme low power from the failed alternator. I doubt you will see behavior like that again.
if you are not running a throttle body (egr flow control valve) where are you getting vacuum from? is there an electric or engine driven pump? the whole point behind the throttle body is to generate vacuum to suck in egr gas, but I noticed the brake booster gets vacuum from the intake manifold. without a throttle body I would think you would lose vacuum brake assistance.
the "ETC" light he is speaking of is the electronic throttle control light. Chrysler has it on all vehicles equipped with an electric throttle body, even the 6.7 cummins.
You must be new here, or at least new to Diesel engines.
Diesel engines do not have a throttle body and do not produce vacuum.
Our CRD engines have a vacuum pump driven off the crankshaft.
The butterfly valve mentioned is for the function of the EGR valve.
Yes, our CRD engine has an electronic throttle.
There is no throttle cable from the foot pedal to the engine.
not new to diesels at all, I guess you just wont let go of the word difference. the egr flow control valve is indeed an "electronic throttle body". never said it was attached to a cable. diesel engines due in fact produce vacuum, as long as there is a restriction on the intake side (egr flow control valve/ another name for a throttle body). if you read my post you would have seen I said the only reason for the flow control valve is to generate vaccum to draw in egr gas. the only reason a diesel engine does not generate vacuum is the lack of a throttle body, so the VM, along with Cummins and many others, installed a flow control valve (electronic throttle body) in front of the egr flow. I understand its a play on words, you say flow control valve, I say throttle body, they are one in the same. unlike a gas engine the throttle body on a diesel has no relation to the apps (accelerator pedal position sensor), or drivers right foot. we are saying the same thing just different words.
you are correct, after reading through dealerconnect, I was mistaken as to where the brake booster plugged into. it plugs into a line at the intake not the intake itself.
