DTC C2105: Right Front TPM Sensor Malfunction: Description

WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

When Tire Pressure Monitoring (TPM) sensors detect vehicle speed of 10-15 mph, TPM sensors will enter powered up stage and begin to transmit identification code and tire pressure information from 0-62 psi (0-427 kPa) to the receiver. Receiver waits for first sensor to transmit information. When first sensor transmits its information 15 times, receiver verifies if all sensors have sent information. If one or more sensors do not transmit information, receiver will set appropriate DTCs for TPM sensor that did not transmit. When vehicle has been stationary for longer than one minute, sensor will enter a power down or sleep mode and will stop transmitting tire pressure information.

DTC C2105 will set when vehicle completes a diagnostic cycle (driving for about 20 minutes at speeds greater than 15 mph) and right front TPM sensor has not transmitted tire pressure information and at least one TPM sensor has transmitted tire pressure information 15 times. When DTC C2105 sets, Driver's Information Center (DIC) will display SERVICE TIRE WARN SYS message and right front tire pressure will be displayed as XXX kPa (XX psi).

DTC will clear when right front TPM sensor transmits tire pressure information to the receiver before a diagnostic cycle is completed. History DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is no longer present. Scan tool and DIC can also be used to manually clear DTC.
