SOURCE: How to use TPMS in Acura MDX 2005

The TPMS light will be visible in your instrument panel like your parking brake would if activated. The TPMS function is activated automatically once any of your tires are improperly inflated. Furthermore, it will identify which tire needs attention.

I doubt they did anymore damage but i`ll bet that the engine was damaged from the training going out such as valve guides and seals and carbon build up on plugs ETC.

2002 acura TL-s engine code p1456

Code P1456: EVAP control system leakage (fuel system).
Probable causes:
1. Wire harness. Check for correct voltage, open, short to ground, short to voltage
2. Control unit software in need of updating
3. Faulty PCM or ECM
4. Vacuum leaks. Damaged hoses or improper routing
5. EVAP system. Check canister, valves, or components. (gas cap excluded because you say you replaced it)

Some or all of the above could be the source of the check engine light problem.

My 01 Acura MDX intermitently stalls and I can be immediately restarted. I had EGR codes & o2 codes. Allof those problems were corrrected. But the engine still continues to stall after highway driving...

This is still a EGR symptom coming up to a stop, Its not going to give you a code and it wont . This can only be found by a data stream, you can try these as a solution clean the throttle body and do a idle air control cleaning with a MAF cleaning, these should solve the problem But I am still sticking with EGR as a problem. But do a throttle body and idle air cintrol with a MAF cleaning,

code P1456 set when there's small leak in the fuel tank system.
Most known reason for P1456:
-Didn't tight fuel cap on until it click for more that 3 time after fueling up and drove the car too long with cap loose.
-or a bad gas cap.
I'll try tighting the gas cap.
clear check engine.
if code come back, replace gas cap and clear check engine light again.
