I want to disable the Tire Pressure Monitor System on my 2007 Chrysler T&C. (The sensors have been removed from three of my tires and the light on my dash is on continuously.) Is this possible?
Please respond by email to racnh4@yahoo.com.
Thank you.

 

The Tire Pressure Monitoring (TPM) system monitors air pressure in the four road tires. Pressure in the spare tire is not monitored.
TPM alerts the driver when tire pressure falls below predetermined thresholds.


The TPM system is controlled by the Wireless Control Module (WCM), commonly referred to as the Sentry Key Remote Entry Module (SKREEM).


There is a sensor (transmitter) in each of the vehicle's four road wheels that operates on a 315 MHz radio frequency. For further information, An indicator lamp located in the instrument cluster and, if equipped, the Electronic Vehicle Information Center (EVIC) are used to communicate system information.


For further information, refer to the Owners Manual or the appropriate diagnostic information.


On vehicles equipped with Tire Pressure Monitoring (TPM), one tire pressure sensor (6) is mounted to each wheel in place of the traditional tire valve stem. Each sensor has an internal battery that lasts up to 10 years. The battery is not serviceable. At the time of battery failure, the sensor must be replaced.


The TPM sensors are designed for original style factory wheels. Do not attempt to install a tire pressure sensor in an aftermarket wheel. If aftermarket wheels are installed and do not contain tire pressure sensors, the system will not function properly and the driver will be continuously notified of a system malfunction.

The serviceable components of the tire pressure sensor are:

Sensor-To-Wheel Seal and Metal Washer
Valve Stem Cap
Valve Stem Core
Valve Stem Nut (with pressed-in washer)

The valve stem caps and cores used are specifically designed for the tire pressure monitoring sensors. Although similar to standard valve stem caps and cores, they are different. The valve stem cap has a special seal inside to keep moisture and corrosion out. The valve stem core has a special nickel coating to protect from corrosion.


NOTE: Tire pressure may increase from 2 to 6 psi (14 to 41 kPa) during normal driving conditions. Do NOT reduce this normal pressure build up.

When diagnosing a tire pressure issue, always check air pressure in the tires first with a known accurate air gauge. Adjust air pressure as necessary to that listed on the Tire Inflation Pressure Label (Placard) provided with the vehicle (usually applied to the driver's side B-pillar). After adjusting air pressure in a tire on the vehicle, allow approximately two minutes for the message or indicator lamp to go out.

Check the tire pressure indicator lamp in the instrument cluster. If the lamp is illuminating continuously, proceed as listed below. If the indicator lamp is flashing on/off for 60 seconds, once every 10 minutes, there is a system fault detected. Refer to the appropriate diagnostic information.

If air pressure in any tire is low, inspect all the tires for leaks. A water “dunk tank” or other water test may be used to check for a leak around the sensor as long as any water at the valve core is removed once the procedure is completed. The water can be easily expelled from the core area by pushing in on the core for several seconds, allowing escaping air to drive out any moisture. Reinflate the tire as necessary. Always make sure the original valve stem cap is securely installed to keep moisture out of the sensor.

If the gauge-read pressure in the tires does not indicate a tire pressure issue, refer to the appropriate diagnostic information.


Tires and Wheels/Tire Pressure Monitoring/SENSOR, Tire Pressure Monitoring (TPM)/Removal:


1. Raise and support vehicle.
2. Remove tire and wheel assembly.

CAUTION: The cap used on this valve stem contains an O-ring seal to prevent contamination and moisture from entering the valve stem. Do not substitute a regular valve stem cap in its place.

CAUTION: The valve stem used on this vehicle is made of aluminum and the core is nickel plated brass. The original valve stem core must be reinstalled and not substituted with a valve stem core made of a different material. This is required to prevent corrosion in the valve stem caused by the different metals.

Start Mount/Dismount Tool Within 10 Degrees Of Valve Stem
3. Dismount tire from wheel following tire changer manufacturers instructions while paying special attention to the following to avoid damaging the pressure sensor:a. When breaking the tire bead loose from the wheel rim, avoid using the Bead Breaker in the area of the sensor. That includes both outer and inner beads of the tire.
b. When preparing to dismount the tire from the wheel, carefully insert the mounting/dismounting tool 280° from the valve stem ± 10°, then proceed to dismount the tire from the wheel. Use this process on both outer and inner tire beads.

Sensor Mounting To Wheel
4. Remove sensor nut retaining sensor to wheel. While removing nut, hold pressure against rear of metal valve stem to keep valve stem from pushing rearward, damaging antenna strap.
5. Remove sensor from wheel

 

Starting with the 2007 Model year, TPMS is required on ALL vehicles SOLD in the U.S. This is a LAW instituted by the Federal Government. The 2006 and earlier systems had a "Technician Level" setting available to disable the system, But This option is no longer used.

Of course you could always remove the bulb........ But that doesnt remove the EVIC message......

EXCELLENT POST! Essentially removing the TPMS is similar to disabling the air bags in your vehicle (not a good idea and probably illegal in your state)

 

Your response to my question was idiotic.
Don't waste peoples time with stupid responses.
"removing the TPMS is similar to disabling the air bags in your vehicle", how dumb can a response be.

If you don't find an answer informative shut your face and move on. You are the one coming here and asking questions, it looks like you are the dumb one, eh? I hope it costs you hundreds to fix it, jerk.
