So, I have been reading some posts on the EBP. I was wondering if either the tube was clogged or if the sensor was bad would cause the truck not to idle high on cool mornings.
No, the truck will still high idle regardless of the EBP sensor.
High idle is dictated by readings from the following sensors:
- IAT (Intake Air Temperature): High idle setpoint (up to 1300 RPM's) is determined by air temps.
- EOT (Engine Oil Temperature): Oil must be below 122* F to increase idle.
Now the exhaust backpressure valve can be disabled if there is a short or open circuit with the EBP sensor. However a plugged line will only give the sensor a false reading, and can in some cases keep the backpressure valve closed during acceleration. In fact, that happened to my truck and was the major reason for me deleting the EBPV and pedistal.
ohhhh...well with the 6636 mod, would that have anything to do with the truck not high idleing...now that you mentioned IAT, is that the sensor i might have ziptied?
Thanks for the info.
If it's just zip tied in the engine compartment, then it's still working like it would normally. That's what I had for a long time when I ran the 6637 filter. Now if you removed the sensor, then you'd have something different.
I don't know of a specific post or guide for it. All I did was pick up a brand new non-EBPV flange and pedistal from an individual. You can check some sponsors to see if they have any. I know Bob at Dieselsite carries the non-EPBV pedistals, but I'm not sure if he has the non-EBPV flanges that go between the turbine housing and exhaust downpipe.
You can also check with Long Island Performance Diesel. They used be a listed sponsor. That is where I got both the non-EBPV pedestal and outlet housing.
