Air sensor replacement or receiver?
I've pretty much read all the threads regarding tire sensor errors - thanks for posting how to reset the sensors! My situation is a little different... after my HREs were put on, I received the tire sensor error. The rear sensors still gave me readings, but the fronts were both XXX (this came up after I drove away - not sure exactly when though). I'm assuming it was damaged or something else as they were all working before I put the new wheels and tires on. Discount Tire is saying they do not know how to reset the sensors and to take it to a stealership to have them reset. Now I know how to do that, I definetly will work on it myself before taking it to a "stealership". Anyway, Discount Tires was going to see which sensor was bad and replace it for me. After they worked on it... I'm now getting RFA codes: C2100C, and 2105C. These codes both relate to the L and R air sensors, but why am I getting the codes now? Would these codes show up using an OBDII? That is what I used before learning how to retreive the codes using the DIC. That may be why I see them now? They called a stealership and they told them that my receiver is bad. If it were, how come my rear sensors are reading okay? Thanks for your input.

Your engine is also bad. Just replace it with a NEW one and send me your old one!
Thats complete
. The receiver will not selectively read the back sensors and not the fronts. You need a magnet and you have to train all four sensors during the sensor training session at the same time. It will ask you to train one then lead you to the other ones in sequence.
Once you train the TPS, clear the DTC's using the DIC and see if the problem resolves. If you still have a problem, I'm pretty sure the sensors that are not broadcasting are damaged. Not the receiver.
The remote frequency actuator (RFA Module) reads your TPS and your FOBs. Do your FOBs work?????

Hi Bill - 
I tried a corvette specialist shop this time instead of a stealership and it is funny you ask about the FOB...the FOB was not on "passive", but yet it was locking my doors as if it were on. I reprogramed all my FOBs except the third one would not reset for some reason. I thought maybe the garage did something to reset the FOBs, so I didn't question it since I know how to reprogram them.

The RFA reads the FOBs and TPS and sends info to the BCM for action. If weird things are happening it could be the RFA or BCM. Check the area around the BCM for moisture/water. If the BCM gets damp. it will do really strange stuff.

How long have you driven on them? Try finding some railroad tracks (bumpy ones) and drive over them. When I got my new tires, one didn't show until miles later after I ran over a railroad track. I figure the motion sensor was stuck.

I had one acting weird a few years ago after a wheel changeover...wound up overinflating that particular tire and drove it around for several miles. Went home and deflated to the 29 cold I run and not one glitch since then.........

I will reset my TPS today (with a disc drive magnet) and if it doesn't reset, I'm thinking it could be a damaged sensor since it happend after the wheels were put on.
I took it in the other day and the shop ended up actually crushing in the outer part of my HRE wheel!
Is it true that if one sensor is bad it moves the other readings to the right? ie: if the LF is bad it will move that reading to the RF, the RF to the RR...? I was told that by a Chevrolet dealership.
Thanks for the other input.

The BCM is in the passengers foot well. Its the big shiney silver box! If there was water in that well, it will not sit there long due to the heat of the underside of the car. To see if that well has/had moisture,,,lift up the carpet and feel the jute carpet insulation. If its damp, you had a leak and the BCM was most likely wet/damp. My 98 BCM was damp so many times and for so long, that it actually corroded the back of the BCM printed circuit board. Talk about doing some really weird stuff, CHEASE!!!!!!!!!!!!!!!!

Tps
A Chevrolet dealer RUINED one of my sensors when installing new tires.
The experienced mechanic DID NOT REMOVE the sensor like it says in the service manual. 99% of the time you are LUCKY. Its that 1% that kills you. A good whack from the bead breaker is all it takes. I had 4 working coming in and left with 4 working going out. Saw the service mganager. Told him the book says to deflate the wheel, slightly break the bead near the sensor and REMOVE it before removing the tire. He had a phone and a LCD screen on his desk. I said thet MAYBE if I dropped the phone or the monitor it MIGHT WORK. MAYBE NOT. He ATE the $145 list price for the sensor. Get your installer to EAT the sensors they BROKE when they installed them. First try reseting them with the DIC and a magnet but if that doesn't work then they were DESTROYED.

Do your wheels allow the use of sensors?
I know most HRE's don't and the sensors have to be banded to the inside of the wheel.
If they worked before the wheels were put on and they didn't work after then the first thing I would look at is are they even with the car anymore.

Did the sensors get put into the new wheels?

So when they do install the LF sensor again, all sensors will need to be reset (and that would be done anyway?) so no worries of them still reading incorrectly since I will not be starting with the LF reading, but rather the RF on the LF? I'll be totally impressed if anyone understands what I just said.... : )

Yes
So if I start reprograming the RF sensor (with the LF prompt), it will move all the readings to the right? Example: LF becomes RF - RF becomes RR - and LR becomes LF?
