Hi folks,
Hope everyone here is OK.
So the Sienna (225K miles now as the kids' beater) somehow developed a
mysterious hole in the inner taillight. I finally found one (a story in
itself), go it and now need to install it.

Anyone done this before? I am betting that there is a trick, and a
feeble googling did not come up with it yet.

This is the only remaining barrier to finally getting this thing
inspected.

Thanks folks,
Tomes

Well, I haven't seen the inside ot a Sienna for four years now. Other than
that, how have you been?

When you say the 'inner taillight', I am guessing you mean the one on the
hatch?

If so, you may have to remove the inner trim panel to access the nuts
holding the taillight in place. There should be screws in the handle,
under some trim covers, and snaps the rest of the way around. They may
have put some access covers in the trim, but I doubt it.

Get a trim removal tool at AutoZone for ~$8. It will save snapping the
retainers. If you're careful you may be able to remove them with a
screwdriver, and they run about $1.25 each at the hardware store. If you
don't snap too many, you may come out ahead!

Hiya Hachi,
So it turned out to be easy. The rear panel just popped off once I took
off the pull-down handle, then there are 4 nuts holding it on, np. Now
to time inspection for when the check engine light is not on (occasional
cylinder misfire codes even after new plugs and wires).

Other than that, the life of the Tomes has been good lately. Been
playing _a lot_ of rock and roll hammered dulcimer lately.

Thanks for the help.
Tomes

That misfire, particularly on random cylinders, can be the result of a bad
MAF sensor or an intake (vacuum) leak.

The job of the MAF (mass air flow sensor) is to detect air temp and density.
The result of this detection is used to map the fuel delivery so that the
desired blend of air and fuel is 14.7 to 1. If the MAF is lying, and the
fuel map goes lean because of this, then a cylinder misfire can result.

You can get O2 sensor errors too. Normally you want your O2 Sensors to
report that the fuel mixture in the exhaust is rich or lean, but the error
you get from this sensor if the MAF is on the fritz is simply Fuel Control
Error, or something to that effect. This error means that the fuel is all
over the place instead of usually one way or the other. A vac leak should
push the Fuel Trim to the lean side, and lean can be detected as a misfire.

One thing to consider is that a misfire is detected by watching the crank
sensor. If a cylinder fires properly then the crank sensor expects to see a
certain amount of work that contributes to the rotation of the crank. If
that work is not detected then a misfire has occurred. When the plug fires,
the next crank position sensor reading should come in a specific amount of
time. If it comes slow, then the work was not done and a misfire is
recorded. The point of this is that a misfire does not mean the spark plug
or wire is bad. It can mean that, but it doesn't have to mean that. If the
MAF is leaning out the fuel map, then it could be picked up as a misfire
because the work that is expected isn't seen. Does that make sense?

I'm not saying that it is your problem, I'm just pointing you to
possibilities for the misfire that continues even after you supposedly fixed
it.

Hmmm...they have changed the inspection. You have to have either 2 or 4
driving cycles on the ECU, and they can tell how many cycles since the
last failure.

I wired up the Tercel so when you turned the key off, it cleared the ECU.
It was turning on after two driving cycles. Since it was a '95, even
though it already had OBD-II they were dyno testing it, so the failure was
never checked. Now, however they will fail it under 2-4 cycles...
