Excellent diagnosis, using a sensor simulator to check if the new sensor will fix the AC and also letting you know if there would be any additional faults before you tell the customer is a great way to diagnose.
Brilliant. I've gotta get the codes read on mine. 2010 focus. Compressor/clutch worked when we jumped the relay for a moment. So I suspect it's one of the sensors. Sick of 80-90deg days with a black 130deg oven. The 3.5v suggestion is awesome.if it's any sensor other than the high pressure I'm just gonna bypass it with a resistive divider. I've got a retired ac dude as a friend he said don't screw with the high side switch but the other ones can be bypassed with out lethality/boom risk
Excellent educational Video , hit the nail first time fix , thanks for sharing and I must say I love mine too it’s great piece of kit to have , I’m wondering if I can use it on fan control module the control wire Ryan .
Good Day Sir, mine has also 4.7 volts, and when I remove the plug suppose to be I have 0volts on the ECU line, but what I got is a 3.6volts, and my air-conditioned on my car is not working, Hoping a positive response for this Sir Have a great day ahead
@@eliteautomotivediagnostics4424 On domestic HVAC, the high pressure sensor is to detect an over pressure and to shut the system down. Does the Fiesta have a low pressure senor as well?
@@supermicrodualcpu agreed. In this case this item is not a switch, it is a sensor that can detect high and low pressures, removing the need to have both. Therefore saving on manufacturing costs and producing a much simpler circuit
Elite Automotive Diagnostics what about with engine running and what readings should there be . I have a focus to look at on Friday . Working from scanners need to know what voltage I should have

Thank you for sharing. Good job. Have a blessed and safe week to you and your family.
Great video! Thanks for sharing.
Nice work Ryan 👍

Great video and a very useful tool,thanks for sharing 👍
Thanks alot mate I've learnt something today.!
Great video Ryan... this tool is on my wish list 😉
Good through diag nice to see keep up the good work

Yes indeed 👍 you will be able to use it on a fan control wire
Nice tool the autosim. I'm curious to see if it can simulate signal to alternator when you want to test it on the table or in the car...
Are you referring to a LIN bus signal ?
@@eliteautomotivediagnostics4424 I mean pwm controlled alternators.
good job
Great video! But how do you know it was the sensor that was faulty and not an overcharged system?
The vehicle was not running so it couldn't be.
nice work
Good Day Sir,
mine has also 4.7 volts, and when I remove the plug suppose to be I have 0volts on the ECU line, but what I got is a 3.6volts, and my air-conditioned on my car is not working, Hoping a positive response for this Sir
Have a great day ahead
Hi. Could you point me in the direction of where to buy the sensor? Same as yours in the video.
You can purchase this tool here: elite-diagnostic-solutions.com/collections/ditex/products/autosim-pro
What is the purpose of the high pressure switch?
Hi there, the purpose is to inform the computer the physical pressure within the AC circuit

What should the output voltage be roughly as u said 4.7 is way to high .
Around 0.5v - 1v with the ign on
Elite Automotive Diagnostics what about with engine running and what readings should there be . I have a focus to look at on Friday . Working from scanners need to know what voltage I should have
@@kendavis504 the readings will vary depending on pressure within the system. The operating range of most automotive sensors is between 0.5v - 4.5v
Was wondering how you knew 4.5v was too much. That's good to know! Thank you, this was a perfect video
