I’m not familiar with the oil sensors, but just from what David initially said it sounds like he should have no worry about his trip(s). My viewpoint is that the Aladdin is a “convenience” add-on Beaver/Monaco system and not the primary CAT reporting one. If his instrument panel gauge consistently shows proper pressure, I wouldn’t expect a derate.
Before replacing sensors, if it were me I’d preliminarily be checking the CAT ECM to Aladdin controller data connectors. I’ve not accessed it personally but have been advised that the controller is behind the front panel of the cabinet over the driver’s street side window, right where summer solar heat on the upper cap can be an issue for any components unfortunate enough to be located up there, and where water leaks have been known to occur.
By its behavior (Aladdin reports fine upon restart) I’d be suspicious of a poor wiring connection in the Aladdin screen/sensor/ECM routing. There are two diagrams for the Aladdin in the ‘06 Monterey Wiring Diagrams book in Coach Assist. It only shows an engine data connector and its controller port, but not where it goes - I’d assume a port on the ECM, but you fellows indicate a separate oil pressure sensor for the Aladdin, which leaves me clueless, although Eric indicates the Aladdin is indeed getting its oil pressure data from the ECM; so what is the other sensor that’s mentioned?
If all other engine parameters show good on his Aladdin and there’s a separate oil pressure data system for it, then yes, the culprit has likely been zeroed in on prior to my wasting readers’ time herein.
