How to get the DIC to ignore the (lack of) tire pressure sensors?

SNISTER · 03-11-2003, 04:35 PM

When I go road racing, I put on some "spare" wheels and tires which have no sensors in them.

The DIC tells me to service the tire sensors -- and prevents the DIC from displaying anything else.

How can I overide this or get the DIC to ignore the missing sensors altogether?

I'd actually like to be able to see my oil temp when at the track....Thanks.

Tech II.

Just hit the reset button. Then it will allow you to choose gauges or anything else like normal.

I'd like the DIC to permanently ignore them -- so I don't get the message every time I start the car. Can this be done?

Tech II will turn them off but only on 2001 or later.

Thanks -- so, since I have a 99 I'm screwed? That seems silly. I will hold out hope there is a way to deal with this.

I read in much earlier posts on this subject that if you don't switch back and forth, sensors-no sensors, that the DIC will drop the code after X amount of warnings.

Or, you could get another set of sensors and have the warning system work. They are in the FS section for $200 off and on.

You're not screwed - you can always buy a new car. :lol:

At this risk of spreading total malarkey, I have heard that the computer will not set any codes if all the sensors are missing and that it needs to be able to read at least one sensor to activate the system. I have also heard exactly the opposite. I don't know if that is true or not. I have never tried it and it seems so simple that if it actually worked somebody would have mentioned it specifically. I am sure somebody here has tried it so you might want to ask that question specifically to someone who has.

Maybe that's what wottogo meant - just leave them all off permanently.

If you want extra sensors and your wheels take them and you can't get find some good used sensors, Ken Fichtner Chevy (CorvetteParts@hotmail.com) sells to forum members at wholesale. GMPartsDirect also sells them. The mounting nut for the sensor is sold separately. In regard to used sensors, they changed the style in 2001 and they won't match your car if you get the newer version. Unless the price is good, I wouldn't put alot of money into real old used sensors because they are battery powered and the batteries can't be replaced - they don't fail real often (supposedly a 10 year life), but who knows how long six year old ones will last.

Thanks for the additional response. It throws a code when no sensors are present -- this is what happens when I put on a set of rims/tire for road racing, so I think that myth can be put to rest.

I would just as soon as run no sensors as my experience has been they don't read accurately enough anyway. On my car, the sensors read a consistent 2-4 psi below what 2 other good quality hand held gages read.

For me, the sensors add little value.

If you want a definitive answer promptly, you might want to contact davidfarmer of this forum, who has a C5 dedicated to road racing. If there is a practical solution to your problem, he's the guy that will know exactly what is involved and you can accept what he tells you in confidence.
