Do I Actually Need a Tire Pressure level Sensor Rebuild?
Is a tire pressure level sensor rebuild really necessary?
If you're asking the question, it means yous're getting new tires and the tire shop wants to rebuild your tire pressure sensors. Yous desire to know if you lot really need a tire pressure sensor rebuild? The short answer is yes. A tire force per unit area sensor rebuild should cost almost $10 per wheel and is worth every dime. Read on for more information.
What is a tire pressure sensor?
All vehicles made afterward Sep. 1, 2007 must accept a tire pressure level monitoring system (TPMS) to alert the driver to a depression tire pressure condition. Each car maker is immune to ready their own pressure threshold at which betoken the low tire pressure indicator shows on the dash. Just the tire pressure warning light must illuminate when tire pressure reaches a pressure that's 25% lower than the car maker's recommended pressure. Driving a vehicle with low tire pressure is unsafe considering 
information technology causes the tire's sidewall to flex and heat up, possibly causing a blowout. The most recent surveys conducted by the National Highway Traffic Safety Administration (NHTSA) conclude that tire failures cause approximately eleven,000 crashes a year. In addition, depression tire pressure dramatically decreases the vehicle's stability and stopping power. Under-inflated tires or worn-downwards treads are a major cause of failure. If that isn't enough reason to cease and inflate your tires when the calorie-free comes on, you should know that low tire pressure as well decreases your gas mileage and wears out your tires much faster.
Tire pressure sensors are available in two styles; valve stem mount, and band mountain (come across the photos)
Both types have a pressure sensor and a sealed battery. Car makers estimate battery life at around vii to x years and it'southward not replaceable because it'southward sealed with epoxy to prevent corrosion. When the battery dies, you must replace the entire pressure sensor. In improver to a pressure level sensor, the unit also includes an dispatch and temperature sensor (air pressure varies 
depending on temperature) and a transmitter to send force per unit area readings to an antenna located in the vehicle. The sensing and transmission protocols vary by car maker. For example, in late model GM vehicles, the sensor takes a pressure reading every iii-secs. when the acceleration sensor determines the vehicle is stationary. If it senses a tire pressure variation of more than ane.2-psi since the final measurement, information technology'll accept another measurement to ostend. It it still reads low, it'll transmit to the antenna. In other brands, the sensor goes to slumber when it senses the vehicle is stationary and wakes up when the acceleration sensor detects movement. The slumber mode is designed to extend battery life.
Why does a tire pressure sensor need to be rebuilt?
Valve stem style tire pressure sensors mount to a hole in the wheel and seal in tire pressure with a safe gasket. Over time, the safety gasket can deteriorate and leak. In addition, the valve stem itself has a spring loaded valve core that allows you to add air. The seal on the valve core tin can likewise degrade over time. Finally, the tire pressure sensor is secured to the bicycle with a metallic "nut." The valve stem threads and nut are exposed to rain and road common salt, causing them to corrode or time. For all these reasons, tire shops recommend rebuilding the tire pressure sensors every time you change tires, since the rebuild procedure must be performed with the tire removed from the wheel. If you opt out of the rebuild job and experience a leak in the tire pressure sensor'due south sealing gasket, you'll have to pay to remove the tire.
Frankly, feel since 2007 shows that very few seals e'er leak. Still, corrosion between the threads and the securing nut has become a major problem. One time corrosion sets in, you can suspension off the unabridged valve stem merely past adding air to the tire. It has become such a trouble that many shops now warn you of the possibility earlier they'll even rotate and balance your tires and check air pressure. If the tire pressure sensor breaks, you must supercede the entire sensor and pay for the replacement yourself. The shop will non be responsible.
What is a tire pressure sensor rebuild?
In one case the tire is off the wheel, the shop unscrews the retaining nut (run into photo) and discards it. Then they remove the sensor associates from the wheel so they tin can remove and discard the rubber seal. Next, they install remove and discard the valve stalk core. The technician and then obtains an advisable tire force per unit area sensor rebuild kit to match the tire pressure sensor used in your vehicle. The rebuild kit for tire pressure sensors usually includes a new rubber seal, washer, securing nut, valve core, and valve stalk cap.
The technician replaces the seal, washer, cadre, and nut with the new components and re-assembles the tire pressure sensor to the wheel. Finally, they secure nut using a special torque wrench because over-tightening tin can damage the sensor and under-tightening tin can issue in leaks.
The $10 charge per cycle covers the parts and labor.
What if yous don't approve the tire pressure sensor rebuild charges?
If you decline the tire pressure level sensor rebuild, yous assume all liability for future air pressure leaks.
What if yous need a new tire pressure level sensor?
If you have your tire rotations performed at the dealer and the tire force per unit area sensor breaks or the battery fails, the dealer will replace it with an (OEM) part. OEM TPMS sensors range from $50 to well over $200. Only many companies make aftermarket parts sensors that perform only as well as the OEM units for a fraction of the toll (like $25). I've listed a few of those below. The downside to installing an aftermarket sensor is that they more often than not require software programming with a universal TPMS programmer—something the dealers don't have. However, tire shops DO have those tools, which is another reason why you shouldn't buy tires at the dealer or have tire service done at the dealer. If the dealer informs yous that y'all need a new tire pressure sensor and the sensor price is high, contact a local tire store and enquire for a quote for a new aftermarket TPMS including labor and programming. That can save a package.
