1C-13 Engine Electrical Devices: Mass Air Flow (MAF) and Intake Air S5JB0A1306019 NOTE
1) Disconnect MAF and IAT sensor connector. MAF and IAT sensor connector (1) disconnected and 3) Turn ON ignition switch and check that voltage is battery voltage. 4) Turn OFF ignition switch and connect connector to MAF and IAT sensor. 5) Connect special tool between ECM and ECM connector referring to “Inspection of ECM and Its 6) Turn ON ignition switch and check MAF signal voltage between “C37-26” terminal circuit and “C37- MAF signal voltage between “C37-26” terminal 7) Start engine and check that voltage is lower than 5 V and it rises as engine speed increases. MAF signal voltage between “C37-26” terminal 8) If check result is not as specified above, cause may lie in wire harness, connector connection, MAF and Mass Air Flow (MAF) and Intake Air S5JB0A1306020 CAUTION !
• Do not disassemble MAF and IAT sensor. shock. • Do not clean MAF and IAT sensor. should be replaced. • Do not blow compressed air by using air gun or the like. • Do not put finger or any other object into MAF and IAT sensor. Malfunction may
