I just put on my summer/fall wheels 18" JCW R113's and kept my original TPMS sensors in my my stock 16" s winders and wanted to know if there is any way to cut the switch or bypass the senors so i can get that annoying little light from flashing as well as the exclamation point on my tach....

I have an 2008 MCS!!

thanks guys!

 

Not as of yet. Only a piece of electrical tape for now

 

i am willing to do minor surgery to jade : snip snip!!!

you can buy extras to put in the other set of wheels

 

Yeah i kinda wanted to save $300 and possibly put it toward a future mod instead of some stupid sensor in my wheels telling me i need air!!!!

 

Or you could get the TPMS removed from 16s and put in a sealed pvc pipe container w a tire valve stem at the other end. Inflate to 32 psi and keep in car.....

3" PVC with end caps,
bubble wrap to protect TPMS
valve stem

There you go! Bypass!!!

 

I kind of like the stupid sensors, I worry much less about the tire pressures now. I hope I'm not putting unwarranted trust in this system.

 

I hate the TPMS sensors, it's just another way to spend money and increase the cost of vehicles. I feel the safety issues and gas savings because of them are insignificant compared to the $300 or more they tach on to the price of new cars. I think simple cars will cost less and run longer. Too many gadgets are bad :(

I just don't think it's that difficult to visually check your tires every time you fill up w/ gas. Or check w/ a gauge every 6 months or so. ..anyway, we all have our opinions I guess.

 

I'd like TPMS that would provide a readout by wheel of the actual pressure

 

I prefer the old method of using the ABS sensor. which allowed you to change wheels and not worry about this "sensor" shenanigans

 

so is there no way to bypass this or cut some wire on the sesors....?

 

Nope.I tried disconnecting the module(drivers side panel in boot) but did not work.

 

or lack thereof, of TPMS is that a very large percentage of car drivers never check thier pressures, no matter how easy it is. This is coupled with low tire pressures contributing to roll-over accidents, which are the most lethal type. So you make sure that there's a way for the average driver to know that the tires need air, and hence cut down on the number of fatal roll over accidents.

The TPMS could easily be capable of reporting absolute pressures, but it doesn't give this info to the driver yet.... I'm sure higher end cars will soon.

And the $300 cost is retail to replace the sensor. For the cost in a new car it's much, much less. FWIW, the sensors are rebuildable, but are not standardized. So getting the right parts to change the seals and the like isn't easy....

The reason why we have this 'improvement'?

Ask your elected representatives......

On your behalf they made this a LAW........

did they represent YOUR opinion?

Dunno? Who's fault?

 

as to why we have manditory seatbelts, collapsable steering columns, air bags and ABS systems. Same for headlights, turn signals and brake lights. Some of these items we all (I hope) like, some not so much so....

I haven't yet seen data as to if they are effective in reducing roll-over accident rate as intended. If they do, what's the problem? If they don't, then it's a waste of money.

ps, if you think that gov isn't representing your interests, vote differently! If the interest doesn't carry the day, that called "democracy".... Get used to it!

 

Just found this:

I would have to think there would be cheaper ways, but depending on how it works this could prevent you from ever having to buy the stupid sensors. If that was the case it might be worth it. Too bad there is no info.

 

Because radials show very little indication of pressure, runflats show almost zero indication of being flat just by looking at them. Eyeballing them and using a gauge every 6 months is most likely to lead to six months of wrong tire pressures. I'd check them every week (ideally) and every time before a long trip. Checking them usually means letting a bit of air out of the tires anyway, so sooner or later your need to pump them up a bit. With the sensor in place I just don't bother checking them anymore, (I'm not really sure that's a good thing though).

The trouble with that is it was quite insensitve, it really only tells you about flats, not low pressure. I only got a warning with the old method when the tires were down 11lb, down about 1/3 of the ideal pressure. I could have been driving around for weeks on a 10lb down tire and it wouldn't warn me. I'm pretty sure 10lb down is not good for the tire.

 

It actually started some years ago with the FORD Explorer Firestone tire safety issue. The public cried out and congress reacted by making it mandatory. It is definitely a safety issue,,though a PITA I am all for safety!

 

that this is a way to mount up the sensors and pressurize them, just like the suggestion posted above...

The reason the wheel speed sensor lost out is it's a relative measure, not absolute. So you can just press the reset button and go around with low pressures (as I'm sure many do, or did).

Sensitivity is an issue in programming, more than anything else. Mine went off at about 5-7 lbs low on one tire.

oh well that is a ridiculous cost for that

 

"the factory sensors are required".

tirerack sells 4 replacement sensors for 200$. they come in two pieces the sensor/transmitter and the valve stem itself. it comes out to like 32$ per each sensor/transmitter and ~18$ for each valve stem: not too bad if you break it down like that
Tire rack sells them thru ebay

looks like the corvettes appreciate it

I sure hope our car doesn't do something stupid like that.

 

wow. $235 for a bypass... Ow. I would be cheap and do the DIY like I posted above. Unfortunately, you need to keep it in your boot....
