Today we will be working on a 2007 Toyota Sienna V6 with a bad ignition coil. Depending on where the bad ignition coil is on your car, and the error code will tell you, this will either be an easy job or a very time consuming and somewhat difficult job. To expose 3 of the ignition coils it is actually very easy. In my case I have a bad ignition coil in the easy place, but I’ll explain to you where the trouble comes in if you have a bad coil in the difficult to reach cylinder bank. So this cover right here just pulls off, there’s some friction fit points that hold it in place so you can easily remove this. You can see where it connects at these three points here, here and here.

Here you can see 3 ignition coils on this cylinder bank. The other cylinder bank is behind all this. You have to take off the manifold and unbolt this vented grid up here. That’s actually quite a bit of work. Fortunately for me the error code indicates that it is just this ignition coil that I need to replace. So I will be going through the process here on these. If you are going to have a mechanic do this, the cost of labor is easily 3 to 4 times as much depending on which cylinder bank they have to access. So in my case I have the error code: P0356F - P035 followed by 1-6 is telling you the ignition coil location.
