Code C1718 Infiniti Description

The C1718 Infiniti diagnostic trouble code indicates a malfunction with the rear right tire transmitter pressure sensor. This sensor is responsible for monitoring the air pressure in the rear right tire and transmitting this data to the vehicle's tire pressure monitoring system (TPMS). When this sensor malfunctions, it can lead to inaccurate tire pressure readings being displayed on the dashboard or no readings at all. This can potentially compromise the vehicle's safety by causing improper tire inflation, leading to decreased fuel efficiency, poor handling, and increased risk of tire blowouts.
