IF they are current limited, then use a 9V battery, see if you get any movement
from them. They have INTERNAL resistance, that doesn't mean they are
current limited. They have coils in them. The TCC solenoid coil acceptable resistance,
measured at the harness connected to the solenoid module, is 9 to 16 ohms. The other
solenoids, 16 to 45 ohms. A 9V battery may energize them. However, all you need
to do is use a multiplier and test the resistance on them. SO, say you test the
TCC solenoid, and got 13-14 ohms, well, that is in the 9-16 ohm resistance range.
SAme with the others, if you get readings within 16 to 45, then they're good. You
don't need to apply voltage to test them.
Here's the thing, after the work involved in removing the solenoid pack, and if you suspect that one
of them is bad; then it's not a bad idea to simply buy a newer, updated module for a couple hundred
bucks, and throw it back in. If you guessed wrong, and it was not a solenoid, then you have at least
updated, and bypassed possible near-future problems. You can get solenoid packs on eBay.
