Ambient air/barometric pressure sensor
Here's the scoop: It's an '03 Allegro Bus, Freightliner chassis, Cummins ISC engine. I need to replace this sensor but I can't find it. Cummins Quickserve has a TSB on this (TSB100488) informing us that the new one is mounted differently than the old one. I'm good with that but I need to find the present one first!!
The part number of the sensor is 4902720 which supersedes sensors numbered 3080407 and 3085140. The new one was introduced in Feb '06. The TSB says the new sensor "will not" thread or bolt into existing sensor locations so the old one may not resemble the new one. The new sensor is to be cable tied and taped to the wiring harness, parallel with the ground, and pressure port facing down.
Any help is greatly appreciated. I've already called Freightliner and they were no help.
