Air Temperature Sensor (740 GL REGINA EFI)
- Disconnect air temperature sensor connector. Using an ohmmeter, connect ohmmeter leads between air temperature sensor terminals.
- Ohmmeter should read according to specification. See AIR TEMPERATURE SENSOR RESISTANCE table. Replace air temperature sensor if ohmmeter reading is not within specification.
