Hello there, I am a Master Automobile Technician certified by Honda and ASE. I can help you with the problem you are having with your Honda!Give me a bit to gather the information you need. Thanks.
Well that didn't go so well. I moved the two way valve out of my way and brought the FTP sensor down to me so I could do this test......The hose to the two way valve came off easy, the other hose was being a bitch and did not want to come off. I ended up breaking off the tube extending from the FTP sensor inside the second hose. I read it out anyway, got 2.47 Volts at atmospheric and it decreased when I applied vacuum(with my mouth) to the remaining port. It would return to 2.47 with no vacuum. Not sure if its relevant but the hose that I had issues with had some white stuff(sticky glue-like) around the last 1/4" of it.
* The vacuum pump we have in our shop(which is an FAA Repair Station(we fix airplane parts i.e. valves, actuators, fans, pumps, computers, etc.)) can build up to about 30inHG vacuum and Im not sure the exact volume of the tank we have it hooled up to but its probably a few hundred gallons. A guy was trying to suck some hydraulic fluid into a 55 gallon drum with it and ended up crushing the 55 gallon like you would an empty beer can in your hand.
Forgot to mention, Im obviously going to have to replace the FTP sensor at this point, what would be the next step?
