exhaust brake issue
Hi everyone, Any of you have experience with this... 02 Holiday Rambler Endeavor exhaust break stays energized when throttle is applied. Throttle positioning sensor, relay, solenoid and act...

IMO, we are stuck on two points:
(1) Exactly what type of engine braking are you talking about? We are discussing two different types of slowing down, exhaust braking or engine braking.
The main difference between the two is in how they operate. A Jake brake (or engine brake) creates braking force by releasing the compressed air inside the cylinders. In contrast, an exhaust brake blocks the path of the exhaust, causing an increased pressure in the exhaust manifold. Jake breaks cost $2,000+ and, therefore, are usually not found on RV's. Jake brakes are normally found on the 18 wheelers.
(2) Now, if we assume that that you have an exhaust brake, how to use it? IMO, many RV manufacturers put the exhaust brake system into "armed" mode when the engine starts up. Then, the braking system becomes active when you depress the brake pedal. Then, the system goes back to "armed" mode when you press the accelerator. Usually, the coach has a switch to choose between on and off for an exhaust system.
So, to the OP, IMO you have an exhaust brake with the "automatic on/off" system with a switch somewhere to turn it on. That switch is currently in the "on" position. As long as you are not experiencing any engine performance issues, it would appear to be working correctly.
