RE: Cm870 engine brake
how I check the circuit is that I pull the sensor out of the hole, spray brake cleaner down into it, then have someone crank the truck.. see if it comes blasting back out of the hole.

I have found a lot of them clogged up this way, and it is not always in the cross-pipe, but in the thermostat body itself sometimes.
