auto parts,VVT oil control valve part number needed so I can replace the part.

2000 Toyota celica gts 2ZZ engine. I want to replace the VVT oil control valve, aka cam timing oil control valve. Is part number 15330-22020 the right part, and can the same part number be used for the left and right side (I think they are referred to as I (injector) and L (lifter), ie. VVT-i and VVT-l). I tried (a mistake) to use part number 15330-22040 and the left side (seemed to) work; the right did not.

My car has 146000 miles.
My car has an automatic transmission.
