Why do the two front green tire lights on your 2001 montero sport xls 4x4 keep flashing and has one sold green light for the back tire?

The flashing front green tire lights on your 2001 Montero Sport XLS 4x4 indicate a potential issue with the tire pressure monitoring system (TPMS) or that the system is not detecting the front tires properly. The solid green light for the back tire suggests that the TPMS is functioning correctly for that tire. It's advisable to check the tire pressures, as low or uneven pressure can trigger these warnings, or there may be a fault in the sensors for the front tires. If the issue persists, consulting a mechanic or servicing the TPMS may be necessary.
