The 01-04 RFA would be compatible with early C5's but I don't believe you can use it to delete the TPMS. The ability to turn off/on the TPMS in the 01-04 was through the BCM with a tech II.

 

Schrader has them for $65 or so for the early ones and $50 or so for the late ones brand new. OEM-you can find them on Amazon and I think they're guaranteed for 7 years. What I bought for my second set of rims.

 

Here ya go. I put in a set of these and I'm happy as a lark.

For an 01-04...

I don't know how accurate the stock ones were, but according to my pressure gauge, one of mine is off by about 8 or 9%. The other three are within 3%. Doesn't matter to me, I know they can't be perfect. I didn't expect the tolerance to be 3psi of error though.

 

I think you guys may be missing the fact that I asked about using a Z06 RFA. My understanding is that the Z06 RFA does not communicate with tpms, and talks only to the door fob. Therefore, if I use new door fobs compatible with the z06 RFA, then deleting tpms should be achieved.

All this assumes the later model z06 RFA is backwards compatible with the 2000, which you have confirmed.

Or am I missing something?

 

Extra tpms is what I am trying to avoid. I would prefer to just delete tpms, check pressure manually, and not have to equip extra wheels with this.

 

The sensors are nothing more than gauges with rf links that broadcast their readings to the car so they can be displayed. Since none of the 5 gauges you are referring to are calibrated you really don't know which one or if any is correct. Without calibration your hand held gauge could be the one that is wrong.

No, I didn't miss anything. A z06 RFA IS an 01-04 RFA and DOES talk to the TPMS. The only difference is on the z06 the RPO for the TPMS has been turned off through the BCM.
If someone with a z06 wanted to add TPMS all they would need to do is pop the sensors into the wheels, hook up a tech II, and turn the option on.

 

Ya, I'm with the others above. There is no Z06 specific RFA module and changing the RFA won't turn of the TPMS. The 01-04 coupe and Z06 both use the same RFA module. The TPMS is turned-off in the BCM and the option was added in 01 for the Z06. You would need to retrofit a 01-04 BCM to be able to turn-off the TPMS.

But hey, go try to find a Z06 RFA and install it if you want....

 

For clarification, when I say TPMS I refer to the Tire Pressure Monitor System. Sensors > RFA > BCM > DIC.

 

Not trying to buck the consensus. Just trying to understand. Thanks for the helpful info on the details of this system.

I guess I must have misunderstood jonnyc at posts 12 and 21.

 

You didn't misunderstand anything. What he posted was wrong.

 

We spent more than $200 just talking about it...

Do what I did, bite the bullet and spend the coin to get rid of the annoying DIC messaging, plus you get the added benefit of knowing when you picked up a nail driving that long cruise! Small investent in comfort and security!

 

When my gauge repeats to within nothing, and it says the same number on all 4 wheels, and the sensors do not say the same numbers, guess what, the accuracy of the sensors is off by the calculated percent. I don't care if 3 are right and one is wrong, 1 right 3 wrong, all 4 wrong, or all 5 wrong, I can tell you that at a minimum, ONE of the 4 is wrong. That's all I was saying. As I have built electronic gizmos for non-contact measuring for decades, I'm familiar with the calibration processes. Both for sensors and mechanical measuring instruments. I am just surprised the accuracy is so far off.

+ or - a psi or so in my tires isn't gonna change anyones lifestyle. I'm not saying I use the things to set the pressures. Just that once the pressures are set, the numbers they give are not particularly accurate. As long as they tell me when the tires are out of spec, I'm happy. I check mine on the dash often, and all I care about is that they are somewhere in the ballpark. I just don't want the dash lighting up and bells dinging every 3 miles, and it was worth $110 to me to buy them and have em put in.

Why do I say $110? Cause I paid $90 for installation, and $25 for batteries for the old ones. Installed them and sold them at auction for $5 more than I paid for the new ones.
