Hi, I'm a new Toyota owner, I bought a 2009 Sienna LE for $500 that has a P0306 and a c1201 dtc codes. I'm needing a wiring schematic so I can test the coils, harness and ECM and have been unable as of yet to locate a specific year and model diagram of the 3.5 ltr VVT-i engine. Does anyone know how I can obtain 1 free online or am I better off going to the local Library and just printing off schematics from a manual? I believe I found the misfire issue although I'm at a loss as to why the code indicates cylinder #6 misfire when what I've determined is the #5 coil looks burned and discolored because whoever replaced the plugs last did not tighten the plug in all the way, (left it loose), and that's what I believe is the problem! Anyone have any comments or opinions that will help me resolve this issue before I go throwing $'s into it? ty!
