TPMS Sensor Matching Process Each TPMS sensor has a unique identification code. Any time you rotate your vehicle's tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. The sensors are matched to the tire/wheel positions in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service. The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire's air pressure. If increasing the tire's air pressure, do not exceed the maximum inflation pressure indicated on the tire's sidewall. To decrease air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage, or a key. You will have two minutes to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than two minutes, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions the matching process stops and you will need to start over. The TPMS sensor matching process is outlined below: 1. Set the parking brake. 2. Turn the ignition switch to RUN with the engine off. 3. Using the Remote Keyless Entry (RKE) transmitter, lock and unlock the vehicle's doors. 4. Press and hold the RKE transmitter's LOCK and UNLOCK buttons at the same time, for about three seconds. The horn chirps two times indicating the receiver is ready for the sensor matching process to begin. 5. Start with the driver side front tire. The driver side turn signal lamp comes on. 5-61
