P1507 Throttle code again

Throttle was cleaned up couple months ago, it did happened like an yr ago too, I purchased a second hand from Ebay and it gone wrong in the same way after 12 mths, put back the cleaned up old one, ran fine for 2 mths and again.

But this time doesnt have bunch of codes, just P0102 and P1507,  therefore P1507 is not clear-able via Durametric, even I reset the throttle and can have the code clear for a minute, it would come back again immediately when the next key on.

Sounds like this time I should have a new TB right? Thanks guys.

The first thing I would do is unplug the engine wiring harnesses on the right side of the engine bay and spray them with electrical contact cleaner, then plug and unplug them a couple of times to clean up the contacts.  Do the same with each and every electrical connection on the TB.  With those types of codes they all seem to point to some problem with the TB and control valves on the TB, and the DME is not receiving the correct readings from the TB, MAF sensor and other sensors.

Thanks, I just did clean up the contact of the TB again after home,  but can you please tell me more detail of the wiring harnesses location?

 

But before I did reset throttle, clean up connectors, the throttle % seems to be went back to normal after codes clean and a few car restart...And u never know how soon would it happens again.
