DIAGNOSIS AND TESTING - TIRE PRESSURE SENSOR

NOTE: Tire pressure may increase from 2 to 6 psi (14 to 41 kPa) during normal driving conditions. DO NOT reduce this normal pressure build up.

If a fault in the system is detected, always check air pressure in the tires first with a known accurate air gauge and correct the inflation pressure as necessary. If any tire is low, inspect all tires.

NOTE: If a tire and wheel rotation is not followed by the retrain procedure, the system will not properly inform the driver with the correct vehicle location for a low or high pressure tire.

If gauge-read pressure in the tires does not reflect the data on the EVIC, retrain the sensors, then reevaluate. If the gauge-read readings at each tire still do not reflect the EVIC data, check the accuracy of the air gauge (What is the accuracy tolerance of the gauge being used?). If the gauge used is known to be accurate and one or more gauge readings still do not reflect the EVIC readings, but the remaining gauge readings do, replace the pressure sensor(s) at the suspect wheels.
