Broke valve stem with pressure sensor!
2005 explorer. My pressure sensor on the dash has been going on and off for a few days. I checked my pressure in three wheels and all were at 35 psi. The fourth wheel's metal valve cap was siezed on, so I took a pliers and tried to turn it off. It broke off the tip taking the valve core with it. Anyone heard of this happening? How much to replace? Also, this was the only tire with the original metal cap. The others were replacement plastic ones. I last checked the pressure just over a month ago.

The same thing happened to me with my girlfriends '05 Explorer. I purchased a new valve assembly from the local Ford dealer for around $65 and then had a local shop install it. The assembly threads into the rim and some shops may not want to do this for "liability reasons" so you may just want to bring the whole tire to the Ford shop. Once the tire is replaced on the vehical you may have to retrain the computer if it does not reconize the new sensor. I had to retrain the sensors when I rotated the tires because the computer was confused by their new locations. If you need to retrain, let me know and I will give you the info. on how to do this by yourself without the need to buy an expensive programmer or having a dealership/tire shop do it.

If the caps corrode & sieze, then why did they come brand new on my explorer. Obviously the tire shop that plugged the other three tires (screws) knew enough to replace the metal ones with plastic caps.

The metal caps are needed as they are part of the effective antenna of the transmitter. Just get a new sensor and stem kit. You will need to reset all the sensors with a magnet..Get magnet on ebay from guess who...LOL

From TPMS 101's website: "As a precaution, warn your customers about using aftermarket metal valve caps. Many are made from steel or brass, which will corrode the aluminum valve over a short period of time"

My 05 has all aluminum caps from factory. The book says not to use plastic as its part of the antenna...
The TPM valve stem cap is made of aluminum and the valve core is nickel-plated for resistance of corrosion. The outer end of the valve stem functions as the sensor's RF antenna. Always place both the cap and the sensor/valve assembly on a clean, dry surface when they are removed from the wheel.
CAUTION:
- If the metal stem cap is stuck, DO NOT use plies to remove it -- it will break!
- DO NOT use a self calmping air chuck on the TPMS sensors, valve stems will break off! These things are VERY fragile!
- Valve Cores of the TMPS are not the same as regular rubber stems, do not lose them.
- DO NOT replace cap with a rubber one, it will mess up the transmitters
- DO NOT use "fix-a-flat" with a TPMS; it will clog the sensor and render it broken.
