UPDATE Got my transducer :)

Thanks you have a PN for this transducer? place to buy it? My truck rarely see anything but gravel roads, but that could change

Update Replaced about 6 in of black plastic CTIS line that had 2 holes in it from previous welding nearby. I was fortunate it didn’t get into the wiring at same spot. Using the jumper I could hear air being routed to the tires at each tire. No apparent leaks. Hooked up the CP to the CTIS...

Great! So its a differential pressure valve. When I fix the leak it will operate as required. Thanks. I hauled 25 loads of gravel out my neighbor's creak for his driveway about 3 weeks ago. He wants to buy my truck.... ha ha ha But now I can use his excavator yeah

Update. My friend came over to help locate the CTIS leak. While I was waiting the couple of days for his schedule to clear, I plumbed in a gauge and a shop QD. Now I don't need to run the engine to fill the air tanks. The shop air will maintain it while trouble shooting. Found three...

The lines on the gauges are approx. I’ll pay closer attention to them. I have lots of brass fittings and an assortment of gauges. I will “T” a gauge between the drain valve and tank. I was thinking about putting in a quick disconnect for shop air there. I have a friend coming over Friday to...

Wow! Thank you. I have my homework assignment 😉 I followed the manual. If all lights are flashing. Shut everything off. Shut off engine. Turn on the main power swt. Push the run flat. Start engine. The run flat AND the hwy lights flash. After the engine is running for maybe 2-3 min. All lights...

1999 LMTV All lights flash on the CTIS. I followed the manual to reset. Doesn't help. Guy on YouTube replaced the pressure switch on side of wet tank. Seemed to fix his. But didn't mention the PN or where he got it. I found the manual reference to change that switch. Can't seem to find a PN.
