• Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
• The following DTCs are not detected: DTCs related to MAF sensor, ECT sensor (other than P0116),
IAT sensor and barometric pressure sensor
1) With ignition switch OFF, connect scan tool.
2) Turn ON ignition switch, clear DTC.
3) Drive vehicle more than 40 mph (65 km/h) for more than 12 minutes.
4) Stop vehicle.
