DrRich 1 Posted May 17, 2011 Report Share Posted May 17, 2011 Hi,I've got an Android phone and bought a Bluetooth adapter to plug into the OBD port. It talks to my phone via the Torque app which I have paid for (as it's such a superb app I wanted to thank the author).The app is updated frequently, often adding new features and yesterday I noticed that in the list of sensors with data it showed "Boost/Vacuum". I had a look, expecting garbage, but found that it shows a reading which tallies with my vacuum gauge - eg 22mmHg at idlw (closed throttle) dropping to eg 5mmHg with the throttle open. It varies during driving in exactly the way you would expect.So my question is, how is it getting this reading - I'm unaware of any MAP or vacuum sensors on a '96 OBD2 VR6..?!?If anyone knows, I'll be very interested to find out.Cheers,Rich Link to post Share on other sites
The Monk 50 Posted May 17, 2011 Report Share Posted May 17, 2011 Don't know bagger all about the app, Rich.Maybe a HUGE shot in the dark but I don't know if this is either a temp or pressure sensor.... sensor of some kind anyway.The vac hose for the servo assist is on the right, 2 x HT leads.... underneath and directly to the left HT lead is that sensor with plug.Please correct me if I'm wrong people.

DrRich 1 Posted May 19, 2011 Author Report Share Posted May 19, 2011 This one:http://www.amazon.co.uk/Soliport-ELM327-Bluetooth-Diagnostic-Scanner/dp/B004KL0I9I/ref=pd_sxp_f_ptWorked immediately out of the box with the phone. Bit harder to get it working with Vista though (useless Microsoft cr*p). Works fine under Windows 7 but VAGCOM doesn't (well, not my older version at least...)Thanks UM, guessed it might be load since I'd never read about any vac sensor in the manual.
