As I get older, I’m looking to retrain. My background was in sales for 20 years but 10 years ago I became an MOT tester. I don’t have a great understanding of electrics but I feel I really want to get into the diagnostic side and work things out and help fix things right first time.

Years ago i tested a Ford Map sensor with a voltmeter. The signal stays on 6Volt. With the scope I saw a variation of the frequency. This mapsensor signal was frequency depended. Why 6 Volt? The frequenty changed but the duty cycle stays on 50%. So my voltmeter indicated the half of the battery tension. 12 V x 50% = 6Volt. This prove a scope is a very important instrument. Thanks Dan for this video.

Excellent video. That feature on the power probe hook is definitely useful.

Flair4Air, I love it!

[@panzerveps]

Great video! This fault is very common on this generation of VAG engines, so I always check there first. Never experienced an open circuit on a map sensor, but several issues with crank and cam position sensors and coolant temperature sensor. My guess was the connection housing on the sensor was filled with oil. Also a common problem, but only on cars with the sensor placed near the inter cooler.

[@Diagnosedan]

[@wearethe80s4sure]

Dan, cool video as always. Going to check my wires on my 750li 06. Will check as over here in Canada, the MAP sensors are so darn expensive. When i look at the sensor it appears brand new?? Will check the low point in wiring harness as well. Not sure why they made the wires so dainty? Also, watched your video on VW air problems. My sons 08 Tiguan has an ac problem...will tell him to check temp sensor and blower resistor? Problems, problems, problems. My front passenger window stopped the other day as well. I'm kinda thinking it is a ground problem effecting a myriad of problems. Now my Porsche 911, i took it to a shop once upon a time. The cruise was working when it went in...they unfixed it some how. I just tried putting some wd40 in the cruise control lever? WD40 worked on my power window and moon roof switches. So hey give it a shot. I remember the mechanic saying we disconnected the decelerater vacuum as the car will perform better?? I say some mechanics just scare the crap out of me. PS Also watched your video on the ABS module where you found another one of those dainty wires. Your the greatest. Too bad you couldn't diagnose via what's app.

Another win, good work Dan..

[@gearstil]

Very nice, but correct me if I`m wrong: Short to ground in the ground wire could not be, the fault code can not see that, that will make the sensor be on all the time, but showing the correct pressure. -disconnect the sensor -pin the 5 V reference, connect test light to bat - . If test light on, good reference. Otherwise bad reference. -pin the ground, test light to bat +. If test light off, bad ground. -pin the signal wire. With test light to battery +, watch the scan data. If no movement, bad signal wire. Otherwise, bad sensor.

[@Diagnosedan]

gearstil Remember that the faultcode is set on the signal wire. And the signal wire can be shorted to + / - puling the signal up or down!/😁

[@gearstil]

DiagnoseDan I think the last test convers that also. Test light to bat + touching the signal wire and no responce from the scan data...

[@soranghafour]

@@Diagnosedan Great stuff on your channel, and you're one of the best teachers on youtube when it's about automotive knowledge. Of course not everyone can afford all the tools you are using. But i have one question: wouldn't it be to much putting 2 bars( reading on the gauge) of pressure in the intake system? And one note i have regarding the map and gauge pressure, that i think are different. The fact that the scan tool was reading the same as the gauge(aprox.50kPa), was just a coincidence, because map is showing the difference in pressure, i mean map is equal to atmos. pressure minus gauge pressure. I might be wrong. You could really help us with a video about a faulty turbo system and map sensor,their relation and how to diagnose using a gauge and the scan data, or using any other method you know.
