Code C2134 Lexus Description

The C2134 diagnostic trouble code (DTC) for Lexus vehicles indicates that there is no signal being received from transmitter ID 4 in 2nd mode. In simpler terms, this means that the vehicle's tire pressure monitoring system (TPMS) is not able to communicate with the sensor located in the fourth tire in the second mode of operation. The TPMS is a crucial system that monitors the air pressure in the tires and alerts the driver if there is a significant drop in pressure, which can affect the vehicle's handling, fuel efficiency, and overall safety.
