Searched but found no info on installing TPMS on my C5Z, which has none. I know I read somewhere that this is doable

Cliff8928

Yes, it just needs to be enabled in the BCM and obviously have the TPMS sensors installed in the wheels and learned.

As usual, Cliff and 8Vette7 nailed it. Some dealerships don't know how to initialize the TPMS program on a z06. (ask me how I know...) My dealership has morons. (whoda thought it) I brought printed instructions and he wanted actual screenshots of the Tech II windows... so here they are.

I hope you need/use this; it took me an hour to find it. (No guilt intended; it was an intellectual challenge I couldn't abandon.) It used to be posted within this forum but the only link I found is dead.

Another version that's quick and short, if your stealership monkey can read--This is the path in the TechII window:
Diagnostics
2001 (insert your year here)
Body
Y
RFA
Special Functions

From there the two TPM options should be there.

I did this up-grade to my 02 ZO6.

If you have never see how the TPS mounts on the wheel, here are some pictures.

Make sure you use some dielectric grease on the sensor O ring and properly torque the sensor nut.

As usual... some high quality PICS from Mr. Curlee
What's the ole adage... A picture is worth a thousand words... except on the corvette forum it may worth a couple thousand word...

Thanks for the great screen shots, now to find someone that has a tech II.
Two questions: 1. Whats the difference in TPM, and TPM DIC options?
2. Do you bring up the pressures under gages, and if you have a low tire, will you be warned on the DIC without doing anything?

Corvette 22

Thanks for the great photos. I have 4 C5 sensors an 02, two 98's and a 97. One has the valve tip broken off just below the threads where the valve cap screws on.
2 questions: 1. Can I get another valve stem, I'm assuming that it unscrews out of the plastic housing, and that's where the o ring is?
2. How can I test these to see if they work, don't they have batteries inside?

Bill Curlee

When you program the BCM for the Tire Pressure Monitor RPO, it allows the IPC screens to show tire pressure readings. Without the RPO, the ZO6 Owner doesnt see those readings.

YES,, you will see low pressure warnings and flat tire warnings. Been there seen that:



Just like any other NON ZO6 car.

Bill Curlee

Yiou CAN NOT mix sensors. You have early sensors 97-2000 and late sensors 2001-2004

They work on different frequencies and are NOT compatable. The late modle sensors will only work in a ZO6.

Bill Curlee

Set the sensors at each wheel and just program them with a magnet. When the Horn BEEPS, its programmed to that wheel//position.
They will program but show tire flat zero PSI

Thanks again, it looks like you bought new sensors. I'm thinking that's a good idea, considering that the originals should be dead by now. I've seen Dorman #974014's at Rock Auto for $36.99 + shipping. Anyone experienced those?

Bill Curlee

Yes,, I got new sensors BUT,,,,,,,,,,,, If you have good proper frequency old ones, you can (If you are good at soldering) dig out the soft potting material on the back of the sensor and replace the old battery with a new lithium cell. Then just RTV the new battery back in place and sealed.. Here is a post that discuses the process:

If you're near Jacksonville, FL PM me. I have a Tech II and would be happy to help you out.
My fee is very reasonable....typically 1 or 2 beers!!

I'm wondering why they removed TPMS for Z06s, there must have been a reason. Weight? How much do each of these things weigh? Even a few ounces of extra weight on the wheels has a much more dramatic effect on performance than if it was somewhere else on the car.

I'm considering adding them to my C5Z next time I get tires, but not if there are performance drawbacks.

neutron82

maybe because the z06 was more likely to be raced and having tpms could cause issues when the tires are intentionally left at lower pressures, just a guess

wamara

My understanding is that the sensors were deemed necessary for the coupe and convertible's runflat tires; conceivably you could have a puncture, and because of the nature of the tire's characteristics, you could be driving on them without realizing you had a flat. As the Z06 had "regular' tires, it wasn't considered a safety-related necessity. I doubt that the weight of the sensors played much of a, if any, role insofar as their not being installed on the Z06. More than likely it was GM saving a few bucks. That having been said, I think it's a great idea to install and activate the sensors; takes all of 5 minutes with a Tech II.
Finding any performance drawback with their installation is, IMO, well nigh impossible. If you can physically sense any performance drawbacks with them installed, you should be a test driver working for a professional racing team, helping them with car setup.

Bill Curlee

100% CORRECT! GM also saved a few bucks not having to install TPMS because it wasn't mandated by the Gov due to using non run flat tires. I installed them on my 02 Z and it save my rim when I had a blow out. Was able to ease it to the side and drive on the deflated tire. The tire was completely flat and the car drove normally on the highway. The TPMS alerted us immediately with zero pressure.

NO reason NOT to install them is you have the cash and time!!
