. This means the vehicle's central computer cannot determine the exact position (e.g., front-left vs. rear-right) of one or more tire sensors. National Highway Traffic Safety Administration (.gov) +2 Technical Details & Fixes Official Technical Bulletins from the NHTSA and Land Rover documentation identify the following: Primary Cause: The vehicle's charging circuit can emit a 125MHz electromagnetic pulse that interferes with the TPMS sensors, preventing them from being localized. Recommended Action: Land Rover typically recommends replacing the complete set of four (or five, if including the spare) low tire pressure sensors with an updated sensor kit designed to address this interference. Interference Check: Non-approved electronic accessories (like some USB chargers or GPS units) can also disrupt sensor signals. Try removing these to see if the fault clears. Reset Procedure: If you have recently rotated tires or replaced a sensor, the vehicle must be stationary for at least 15 minutes, followed by a drive at speeds above 20 mph (32 km/h) for about 15 minutes to allow the system to re-learn sensor positions. National Highway Traffic Safety Administration (.gov) +4 Diagnostic Steps If the fault persists after a re-learn drive, technicians use manufacturer-approved diagnostics (like JLR Pathfinder or SDD) to check the

According to official Land Rover technical bulletins and owner reports, several factors can trigger this failure: TMPS Issue Codes C1D21-05 and C1D18-00 land rover c1d18-00

A known issue where the vehicle's own charging circuit or aftermarket accessories (like USB chargers, radar detectors, or dash cams) emit a 125MHz pulse that disrupts the TPMS sensors. National Highway Traffic Safety Administration (
