I digress off topic for a moment. Hi Landroverman. there is a sensor in the sump area which will stop the engine starting if there is an oil pressure problem,which also will disable the fuel pumps, Recently I saw a Ford Transit with a failed Temperature Sensor that paralysed start, thinking it had o...

I thought that too from the details in the post till I looked it up on Wikipedia. The very reason I looked to be certain before I posted.

Nothing lost. A Piezo Clamp can be used in place of the amp clamp for testing sync and no need for FRP trace. Nothing lost!

Oil pressure Light or Gauge on the cluster. How long for it to go out, and how fast it comes back ????

Live data if available ?

A simple fault and cure - Not so sure I could say that without the Pico's 4 Channels as my tool of choice. Long standing issues with this car, a 2008 520d BMW N47 Engine. All 4 Glow Plugs and the Pre Heat (Glow Plug) Module have recently been replaced with new parts from our Favourite Motor Factor E...

According to Toyota, if I am not mistaken, the blue signal should be right between the missing tooth on red signal, not where it is now. Don't put any eggs in that basket. For Example. Mercedes will give you Cam Crank Diagrams in WIS and Star Guided Tests that you would like to think are accurate a...

Can you specify why the Toyota's FSM tells to measure between the VR-sensor leads in AC-setting from the ECU-socket? Not with any certainty but I guess measuring it that way would fit with the Training and Tools they provide. I am sure there are no viruses in .jpg files. If you could be so kind to ...

FF You may know something that I don't. In 35 odd years I have resurrected many, every one I touched bar one. This one https://www.picoauto.com/support/post51871.html?hilit=audi q7 fan#p51871. Still not fixed and I can have it back if you have any ideas, of course, Gratefully Received Not yet killed...

The best thing to do is scope the signal and take a look.

alas we agree on something Martyn :

painstakingly checked every ultrasonic bond with a very fine tipped pick and they was all good, maybe component failure I would say your testing is flawed. These can always be made to fail and work on demand by stressing the ECU connectors. As you said "Maybe" Maybe diagnostics ??? Not in my arena ...

You ignored my Oil Pressure Theory - Why ???
