What happens if you put wheels on your vette that dont have the sensors.

 

you will get a code on your DIC........... eeuuuwwww!

 

When I go to the track ((drag race) its about 100 miles one way) I drive down on my drag radials, and have to sensors on those wheels... after app 40-50 miles i get a DI message "No Tire sensor in rear' I just hit reset, and all is fine.. but i have to hit reset every time I start the car..

Once I'm home and pull the car in the garage, the computer will pick up the signals from the OEM tires, & I do not get a DIC warning any longer .. unless I drive more than 40-50 mils from the house...

 

"Service TPMS"

 

Maybe someone can confirm this but another possibility is you'll have limited functionality such as not being able to get into comp mode. I know if a sensor is missing (or not properly registered) this will happen. I know one C6 road racer who doesn't use TPS's on his car wheels but says he needs them...he keeps 4 small go-kart tires (with TPS's inside) band-clamped to his roll bar in the cargo area to 'fool' the system.

I'm not sure but some C6's may react differently to not having TPS's. I know another guy that puts his track wheels on (without sensors) and runs sessions all day long without a problem.

Perhaps BEZ06 will jump-in...he's the resident expert on TPS's and TPMS tools.

 

I'm hoping to hear from Bob also....hope he hasn't forgotten about us since he got his new car...

 

I swapped summer and winter tires/wheels at the storage locker last week. I took the TPMS tool with me but not its instructions, so I had to drive home with unregistered wheels and sensors. No DIC messages or any other warnings, but it wasn't very far (about 8 blocks) and I didn't exceed 35 mph.

 

This come's up a lot, as I swap out track tire's, too. I just found it best to go with sensor's in all the wheel's, and popped for the reset tool. You'll be needing the tool for all car's 08' up anyway, so a good idea. Another good idea is keeping a window down while re-programming, or any time the fob is inside the car.

 

It takes longer for the DIC to register a problem if all four sensors are missing than if just one is not working. I had my other set of wheels registered, drove out of the garage and went almost 40 miles before the car said anything.

 

Hi Chris

I'm still here!! My new car is still a C6 - it's just Cyber Gray with a window in the hood!!! It's a 2009, so it's still got the same sensors as all the 2005-2009 Vettes (I think the 2010 may have a different sensor).

I'll be selling my beloved DSOM Z06 (I sure would like the ZR1 in DSOM!!), but I did have the Z06 at the track at Daytona last weekend. Friday through Saturday morning were wet. I ran a couple sessions on Friday in the wet on my street tires, and even though it started to dry out nicely on Saturday afternoon I stayed on the street tires.

Sunday was beautiful and I switched to my Hoosiers and tried to reset the sensors, but one of the sensors in a Hoosier wouldn't trigger. During the relearn procedure, as soon as you trigger one sensor and log it into memory, it wipes out all the other ID#s in the TPMS memory. I couldn't get the one sensor to register, so I turned off the ignition. When you do that in the middle of the relearn procedure the TPMS will not "remember" any of the sensor ID#s - even if you triggered 1, 2, or 3 of them and got honks. If you don't get all four registered within a certain time period of starting the procedure (or if you turn off the ignition before completing the procedure) then no sensor ID#s will be stored in the memory.

I should have just logged all 4 of my street tires back into the TPMS (even though they would be in the pits and not on the car), but I didn't. I just went out on the track with no sensors registered - BAD MOVE!!!

I got the "Service Tire Monitor" message right after start. I could turn TC off, but couldn't get into Comp mode. I figured I'd just run the session with AH full on and try to get the sensors programmed when I came back in.

Well.....After the warm-up lap I started to drive more aggressively and really had problems with the AH intervening. The banking at Daytona is pretty bumpy and you're essentially in a high speed left hand sweeper bumping along at 150 or so, but I couldn't get over about 110 or 120 with AH intervening. When I run in Comp mode I sometimes see the "Active Handling" in the DIC, but with the AH full on the AH was on almost the whole time around the banking.

The AH really seems to jerk the car around as it puts on individual brakes, but the worst part was that whenever I tried to accelerate hard out of a corner the engine would just die - the PCM will pull power (I think it starts by pulling timing, and then will reduce fuel if necessary). Until I would unwind the steering coming off the banking or out a turn in the infield I just couldn't get any power out of the engine.

I'll normally do at least 160 down the front straight, but with AH on I couldn't accelerate much until coming out of NASCAR T4, and I got up to about 130 or 140. After about 3 laps I could feel ABS coming on and see "ABS Active" on the DIC when braking to come off the oval for the infield part of the course. T3 in the infield is a 180 degree turn, and when I started braking for it the pedal went to the floor!!! The Z06 has so much torque I just run the entire infield in 3rd (it will go up to 125 mph in 3rd), but I was well below max 2nd gear speed of about 90 mph so grabbed 2nd and was able to make the corner and limped backed to the pits.

I had a couple hours over lunch until my next session, so I put the car up on jackstands, pulled the wheels, and saw that my right front rotor had a big gouge in it and the pads were very thin. The left front and rears were fine. I guess the AH was putting on the RF brake to try to control something it didn't like about the fast/bumpy left hand turn around the banking. It boiled the fluid (Motul RBF 600) and wore down the pads.

I put on new rotors and pads up front, bled/flushed the system with new Motul, and registered the sensors in my street tires to the TPMS (but the Hoosiers were still on the car and the street tires were in the pits). The last 2 sessions everything worked real well!!!

Just like cclive said in his post above, you're better off leaving your street tire sensors logged into memory than to try to do a partial job and end up with all the sensor ID#s wiped out of memory. I had my street wheels in the pits, so the TPMS would update when I pulled in off the track. As long as a set of sensors (all 4) are logged into the TPMS memory, even if they aren't in the wheels on your car, you should be able to go into Comp or turn AH all the way off.

Like cclive said, and also as alluded to in the Owner's Manual, If you don't have sensors you can drive for approximately one hour until you'll get a "Service Tire Monitor" message, at which time you will not be able to go into Comp mode or turn AH off, and if in Comp or with AH off, AH will automatically come back full on.

So.....I recommend sensors in your track tires. There are some owners that have made a pressure container out of PVC pipe and have stuck a set of sensors in it, or some that have put sensors in go-cart or grass cutter tires and tied them down in the back like Wayne said in his post above.

I believe the 2010 sensors do not require a tool that transmits a radio frequency to trigger them - indications are that they may be able to be triggered by changing air pressure in the tire about 10 psi.

If you can see my signature picture below, click on it if you want to see video of a couple laps around the Rolex 24 course during the event last year.

 

Its nice to see BEZR1 back here in General Discussion....oh wait, he still hasn't changed his name...lol There's very little fun going on in the ZR1 area, so I'm hoping you won't move over there permanently! I knew you could chime in with some good info here on the TPMS!
