Sienna 01 EC1 location - Toyota Nation Forum : Toyota Car and Truck Forums

Hi All. New here. My wife's 01 Sienna has been throwing a P0330 code. I'm trying to find the EC1 connector and have searched this site and Google to no avail. Does anyone have a pict where it is on this vehicle? I want to test the knock sensor wires before ripping the whole intake apart. I have found a "wiring diagram" and Toyota's own under the hood pages, but nothing specific, and some contrasting. Thanks in advance.

Dmac,

Looked at my manuals and found its location on an 00 avalon, since they both share the same engine maybe the location is in the same position. Take a look at these Pics and let me know if it works for you, i'll look through my sienna manual and see if I can find it.
