MTD August 2016 TPMS Aer adjusting air pressure in a tire, allow approximately two minutes for the message or indicator lamp to go out. Tire pressure sensor retraining e WCM automatically learns and stores the sensor's ID while driving aer a sensor has been replaced. ere is no formal retraining procedure necessary. Driving a vehicle with a new sensor for a minimum of 10 minutes while maintaining a continuous speed above 15 mph (24 km/h) will cause the system to learn the new sensor ID code and will clear any DTCs automatically. If a sensor cannot be trained, see the appropriate manufacturer service information. A new sensor ID also can be programmed directly into the WCM by using a RKE-TPM analyzer in conjunction with a scan tool. Once the new sensor ID has been programmed, the RKE-TPM analyzer can be used to update the TPMS by activating the sensor. Demounting/mounting procedures CAUTION: e tire should be demounted from the wheel using the tire changer manufacturer's instructions. Use the fol- lowing information to avoid damage during the demounting/ mounting procedures. CAUTION: e TPMS has been optimized for the original equipment tires and wheels. TPMS pressures have been estab- lished for the tire size equipped on the vehicle. Undesirable operation or sensor damage may result when using replacement equipment that is not of the same size, type and/or style. Aermarket wheels can cause sensor damage. NOTE: If a tire pressure sensor has been replaced, the tire pressure sensors must be retrained. See reset procedures. NOTE: W heels and tires are match-mounted at the factory. Before demounting a tire from its wheel, a reference mark should be placed on the tire at the valve stem location, to ensure that it is remounted in the original position on the wheel. For match-mounting procedures, refer to appropriate manufacturer service information. Tire pressure sensor IMPORTANT: is vehicle uses the 315 MHz TPMS. Although 315 MHz and 433 MHz sensors are identical in size and shape, they are not interchangeable. Always make sure the correct sensor is being used. On a domestic vehicle, the TPMS sensor operates on a 315 MHz radio frequency. Imported vehicle sensors operate on a 433 MHz radio frequency. e 315 MHz sensors can be easily identified by a white outline oval (black center) insignia on the sensor body. e 433 MHz sensors can be easily identified by either a solid white oval insignia on the body or a solid white oval insignia with 433 printed in the center. e sensors are identical except for the oval insignia. e 433 MHz sensors can either have a black or grey sensor body.
