EBPV Braking

[BVMS]

Does anybody know of a simple install to just wire it to a toggle switch? I don't want it on the brake or anything. And How do you clean it? Mine comes on after I drive it 40 miles pulling its annoying! Thanks

the EBPV is an exhaust back pressure valve that closes to make the engine work a little harder when it is cold outside the engine will warm up fast. it should not be closing when you are pulling. something is wrong

the old body style trucks were common for the ebp to shut off when it isnt supposed to , have seen a bunch of these models do that , if you want to be able to control it or even use it as a so called jake brake , you can just wire it to a toggle switch , very simple , one side ground and the other switched 12 volts , not hard to do

Simple. take the two wires connecting to the plug that conected it to the valve, cut the red wire, connect the red wire to a switch, then run battery and ground to other 2 prong on switch and shes all yours

Okay I was reading on it and a bunch of them said diodes and stuff so didnt know. Will unplugging it be bad for it? Wont start leaking or anything?

if you unplug it you will completly eliminate the EBPV from operating, this would not be a good idea if you live in col climate, the swithc would be best. that away you can turn it on/ close it while your truck is warming up then shut it off/open it when your truck is at NOT (Normal Operating Temperature). that away it wont come on when you are pulling.

the diodes are only to keep you from frying the ecm if you left it so it can be activated both by the computer and the switch but in your case you want it to be just the switch, its common with these trucks,both mine do it too, another thing i would look is your thermostat, it might be shot and your coolant might not be getting warm enough which will keep engine temps down making the valve close

Even when you have it wired to a switch it can still come on automatically by the ecm. It will still go into warm up mode by itself even if the swtich is in the off position. The switch only allows for manual ON operation. If the EBPV is coming on during normal driving the ebpv sensor could be bad or the tube going from the pass side valve cover to the sensor could be plugged with soot.

^ not if he just connects the solenoid to a SWITCHED 12V power supply and does not connect the wires coming from the ECU.

not if you dissconnect it completely from the computer it doesnt
