So I continued to research my cel issue and today I came across this onmr2oc forums (quote on the bottom)

and this page lists check engine light codes for gen3 3sgte: http://www.ayrpark.plus.com/errorcodes/normal.htm

code 47 is listed as "Secondary throttle position sensor", and described with this: "[VTA1, VC, IDL2, E2]
Whenever a short circuit or a circuit detachment in the secondary throttle position sensor is detected for over 0.5 seconds." in area of: "* Wirings and connectors (secondary throttle position systems)
* Secondary throttle position sensor
* ECU

Does anyone have any idea as to what secondary TPS is and how to test for its functionality ??????

found this

http://www.ayrpark.plus.com/errorcodes.html

if you go on the rev3 turbo bit, youll see vta2 on the error code 47.....now i have a ecu error code 47, but i beleive many many rev3 owners have this error as well as all rev1/2 to rev3 conversion folk.....

any more ideas??

i cant find anywhere to test for the "secondary" TPS.....the BGB only lists the main TPS with outputs of vc, ta, idl and e2
instead of the vta2, vc, idl2 and e2 thats listed on that page for the "secondary" tps..........
