tire pressure monitors
I have the original tire pressure monitors on my `98 vert. Recently I started getting low tire pressure readouts on my dash display within seconds after driving on cold tires. The pressure is OK however. Is this a sign the batteries in the monitors are worn out, or could it be something else? Originally the problem started in the LF, however now I get RF signals as well.

Tire pressure monitors give low pressure warning at 24PSI or lower. What is the pressure before the drive? Pressure increases as the tires warm up. Are the pressures borderline? 24 - 25 PSI cold?

You are in overtime on you sensor life span. When the battery starts to fail, your DIC will show XXX for tire pressure. Batteries typically last about 8 years. When your ready to get new ones, drop me a PM and I can save you a ton of money.

there may be another option.
last year i was having the same problem on my 99 coupe. tire pressure indicator was throwing warnings at me left and right. darn thing wouldn't stop.
the official diagnosis that remedied the situation
- door lock / tps receiver had committed suicide.
part # 10422621 $ 335 average cost ***
part # 19151480 $ 375
not a do it your self install (for me)
*** - this is the original part #. if you can find a dealer that still has it you might be able to make a deal with them. you should be able to get it for a very good price.
over the past couple of years gm has changed the part number and of coarse the price.
