Code 1125: Intake Air Temperature Sensor
Disconnect DME control unit. Connect DVOM between terminal No. 26 (MAF meter ground) and terminal No. 44 (intake air temperature sensor). See the INTAKE AIR TEMPERATURE SENSOR RESISTANCE . See Figure . If readings are incorrect, check resistances directly on sensor by connecting ohmmeter between MAF sensor terminals No. 1 and 4. See Figure .
