No, that IS the TPMS system. The wheel speed sensors are only tapped for the ABS, nothing more.
TJKJ, I have to disagree about what model years they were made mandatory. First was the SUV category, and I'm fairly certain it was the 05 model year, 06 almost absolutely. My family has two Mercury Mariner hybrids, both 06 model year, and they have the sensors.
Safety? Fuel economy? HAH!!!!! The REAL reason we are all saddled with these things and that they DON'T give any useful info (like WHICH WHEEL is failing or low) is because Ford lost the lawsuit in like 2002... And the industry was required to install these things to alert the driver that there was a problem - The driver was too brain-dead to put down the latte and recognize that the vehicle's handling resembled wallowing in a mud puddle on the highway.
Yes, it sounds like safety might be the reason... But here is the catch that proves it isn't: The idiot light is there to alert the driver to DO SOMETHING (could be anything, choose your own adventure) and thereby ABSOLVE the vehicle manufacturer OF LIABILITY IN THE SITUATION. Ford was found guilty of putting sub-standard tires (not LT rated for the weight of the vehicle, not enough safety margin) onto the Explorers... And then compounding the problem by setting the factory pressure (on the almighty door sticker) at the barest-minimum level to be considered "safe" in "normal" conditions.
Unfortunately, hot highways and extended (1 hour+) highway-speed driving made the tires flex excessively, wearing out the glue liners. Add in the problem of tires not being checked religiously by the owner and maintaining that barest-minimum pressure... And you have the disasters that happened.
Safety might have been part of the ruling, but the real argument by Ford was (somewhat correctly) that it is the owner's responsibility to check the tire pressures. That is what the TPMS is designed to prod you into doing - It says "I have a problem!" without telling you what... So you have to become a detective and CHECK THINGS. The biggest flaw in the system is that the manufacturers are STILL putting barely-capable tires onto heavy vehicles, and then under-pressuring them with the factory ratings to deliver that "car-like ride" out of a vehicle that was originally a TRUCK. Want a car-like ride? Buy a CAR!
But the driving public really should be given transportation ala "Minority Report" where the vehicles drive themselves to the destinations... So that the 90% of the sheeple that are too dense to check their own tire pressures OR put down the latte and drive aren't endangering the ones of us that know how to do these things.
Its 2010... Weren't we promised self-driving cars by now, in everything sci-fi for the last 60 years?
