It may or may not require the tire pressure threshold to be reprogrammed. I am not sure whether most shops will have the personnel knowledge and hardware/software capable to reprogram the TPMS threshold.

Going back to your first post, it sounded like the wheels were changed before. Where the wheels or tires a different size than stock?

Did you check each tire's pressure yourself instead of just relying on the shop?
Ah, I see. I'll ask him if he can reprogram the threshold.

Everything has been the same size as stock, tires and wheels included. This is the second set of wheels on the car and fourth set of tires I believe.

And of course. Checking the tire pressure and topping it off to 32 (or 30, I don't remember what my car specifically needs, I believe it is 30 though) did nothing at all.

If the wheel and tire sizes are the same as stock, then there should be no need to reprogram the threshold. However, a threshold data check can be made to ensure it is at the recommended settings.

The recommended tire pressures (measured cold) are:

LX: 30 psi

EX, EX-L and V6: 32 psi

Just for the heck of it, try bumping up the tire pressure a couple of pounds more to see if the light will go out (for example, if the recommended is 30 psi, try 32 psi; if the recommended is 32 pis, try 34 psi).

I read that inflating the tires to 44 PSI, then deflating to 20, then back to 30/32 will fix the problem. I didn't want to do that because I didn't want to inflate my tires to 44 PSI manually. I'm tempted to try that, though.

These are the instructions which are part of Honda's PDI (pre-delivery inspection).

To make sure the TPMS sensors are operational and
the tire pressures are set, do this:
1. Turn the ignition switch to LOCK (0).
2. Use a tire pressure gauge with a bleeder valve to
quickly lower the pressure in one tire to 18 psi
or less.
NOTE:
• The tire pressure must be lowered by at least
3 psi within 15 seconds, or the TPMS sensor in
the wheel will not be activated.
• To ensure accuracy, periodically check your tire
pressure gauge with the calibration tool
(P/N 07AAJ-000A100, H/C 8298457). This tool
was sent to all dealerships in August 2006.
3. Adjust the tire pressure to the cold inflation
pressure listed on the driver’s doorjamb sticker. If
you are in a cold climate region, make sure the tire
is at the same temperature as the outside air before
adjusting the pressure; otherwise, the TPMS low
tire pressure indicator may show low tire pressure
in cold weather.
4. Repeat steps 2 and 3 for the other three tires.
NOTE: The spare tire does not have a TPMS
sensor. Make sure that the spare tire is inflated to
the pressure listed on the doorjamb sticker.

Getting the TPMS trouble codes will help narrow down what the issue may be.

It can even be an issue with the gauge control module (instrument panel) or TPMS control unit.

This seems simple enough. I'll try this first and if it doesn't work I'm going back to the shop. I'll keep you updated.

Problem solved. I had to go back to a Firestone shop (had new tires mounted and balanced recently, there was an issue with the balancing), they fixed it for free. One less problem to worry about. Thanks for the help.
