Thanks! This is great info and also confirms 5V is correct supply voltage. Turns out all I had to do was clear the fault codes first and then re-do the active test and TB was back to working normal. Put the whole intake assembly back on and car still ran rough at first. Turned car off, did full scan...

Hi, anyone have access to wiring diagram for the throttle body? I removed the intake assembly to do an alternator job and after putting back everything, car runs bad, has reduced performance message and the throttle body seems to not be functioning correctly. Triple checked all connections. Scanner ...

That DTC decode website is a great resource though. Thanks!

later realized I could just click on "service manual" at bottom of screen to get more info, and it does in fact point to the pedal pressure sensor which is the cylinder shaped thing that sticks out of the booster so I'll try replacing that.

Hi,
A traction control warning message is displayed along with the dash light and scan tool shows error code C111802 Brake Booster Release Switch is at fault. Where exactly is this part located please so I can replace it? Is it on the booster itself? Thanks

Scanner was showing CEM not getting a signal from the Steering Wheel Module (AKA lever hub).Both stalks plug directly into this on each side. Also replaced the SAS at same time which was...

Hello, My 2007 3.2 xc90 turn signal switch all of a sudden stopped working. I removed and clean contacts but it did not fix anything. Interestingly, the message display does not respond to the Read button, messages dont change when I turn the wheel and high beams dont work. So nothing works that is ...

my stick shows 30788016 and last 6 on vin is 333560 so i guess i'm good!

I just changed the oil and didn't notice any issue with that drain valve inside the housing but will pay closer attention next time now that i know those can fail. At 12 yrs old and 166k, it still runs good and very little to no oil consumption. This is great info, thanks

I think I'm somewhere between 8 1/4 and 8 1/2 now and level is just about full. Sometimes the level will show higher on one side of the dipstick than on the other which is another oddity. I usually let the engine cool at least 10 min before checking level.
