B2872 Lincoln Code - Tire Pressure Sensor Fault
Quick Answer
The Tire Pressure Monitor (TPM) system monitors the air pressure in the 4 road tires with wheel-mounted tire pressure sensors. Common causes include Low tire pressure, Tire pressure sensor is missing or damaged, Spare tire is installed as a road wheel. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code B2872 Lincoln Description
Each tire pressure sensor transmission is compared against a low-pressure limit (pressure listed on vehicle certification label minus 25 percent, which will be about 6-9 psi). If it is determined that the tire pressure has fallen below this limit, the SJB sends a message to the instrument cluster, which then illuminates the low pressure warning indicator and displays the appropriate message(s) in the message center (if equipped).
What are the Possible Causes of the DTC B2872 Lincoln?
- Low tire pressure
- Tire pressure sensor is missing or damaged
- Spare tire is installed as a road wheel
- Incorrect tire pressure sensor is installed
- Tire pressure sensor installed incorrectly
- Faulty Tire Pressure Sensor
