How do I reset TPSM system/sensors.

Professional scanner needed to find out WHY light is on... Possible failed sensor (sensors have a battery) sensor(s) may need re-calibrating... Guessing at it is moot!

CHECK ALL ELECTRICAL CONNECTION FOR OUTPUT VOLTAGE, AND GROUND, I THINK ITS ONLY TWO WIRES IF MORE THEN TWO WIRES CHECK SCHAMATIC ONLINE IF YOU DONT HAVE REPAIR MANUAL. AND YOU CAN TELL WHAT WIRE IS SUPPOSED TO HAVE VOLTAGE D.C AND GROUND AND MAYBE A COMMUNICATION WIRE TO LINK ALL SENSORS IF RAN IN SERIES ALSO WHY YOU NEED TO SEE SCHAMATIC ALSO CHECK SENSOR FOR PROPER RESISTANCE OR CONTINUITY THREW SENSOR BY ITSELF TO CHECK SENSOR TO DETERMINATE GOOD OR BAD SENSOR ... GOOD LUCK
