I tested all the solenoids except the PCS, will have to dig up a 9V battery for that one, but I did check the resistance between the PCM pins that go to it (no direct 12V from pin E, only gets signal from PCM).
The 3-2 is the newest solenoid since I replaced it back in 2011 when I first encountered the issues. The PWM solenoid click doesn't sound nearly as stout as the 3-2. They are 2 different manufacturers, the PWM has been in there since before I got the car.
Here's the kicker- the TCC solenoid (built into the harness) does NOT click for me. I can't find a definitive answer as to whether it SHOULD make an audible click, but I'd at least think so. I tested 1-2, 2-3, 3-2, TCC, PWM with IGN239 circuit hot with PCM disconnected and used a small wire to ground the PCM connector pins at each solenoid's PCM location. To eliminate the engine harness I went through the case connector on pins E and T straight off the battery. Again, the TCC solenoid does NOT click. Its resistance is still at 24 ohms after this testing through PCM connectors and direct to battery.
