Turn ignition switch ON.\n2. Measure voltage between terminal TE of SG of A/C amplifier connector at each temperature.\n\nOK Voltage:\nat 0°C (32°F):   2.0 ~ 2.4 V\nat 15°C (59°F):  1.4 ~ 1.8 V\nHINT: As the temperature increases, the voltage decreases gradually.\n\nNG\n\nOK Proceed to next circuit inspection shown on matrix chart (See page AC–26). However, if the light is still blinking, check and replace A/C amplifier.\n\n2 Check evaporator temperature sensor.\n\nThermometer\nIce\nOhmmeter\n\nMore than\n10 cm (3.94 in)\n\nN07725\n\nP Remove evaporator temperature sensor (See page AC–106)\n\nC Check resistance between terminals 1 and 2 of evaporator temperature sensor connector at each temperature.\n\nOK Resistance:\nat 0°C (32°F):   4.5 ~ 5.2 k\nat 15°C (59°F):  2.0 ~ 2.7 k\nHINT: As the temperature increases, the resistance decreases gradually.\n\nOK\n\nNG Replace evaporator temperature sensor.\n\n3 Check harness and connector between A/C amplifier and evaporator temperature sensor (See page IN–30).\n\nOK\n\nNG Repair or replace harness or connector.\n\nCheck and replace A/C amplifier.","image":"https://tsrm.sasquatchvc.com/images/mk4/AC/AC_033.png","url":"https://tsrm.sasquatchvc.com/mk4/tsrm/AC/33","prev":{"page":32,"url":"https://tsrm.sasquatchvc.com/mk4/tsrm/AC/32","api":"https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/32"},"next":{"page":34,"url":"https://tsrm.sasquatchvc.com/mk4/tsrm/AC/34","api":"https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/34"},"section_url":"https://tsrm.sasquatchvc.com/mk4/tsrm/AC","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/1","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/2","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/3","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/4","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/5","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/6","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/7","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/8","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/9","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/10","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/11","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/12","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/13","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/14","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/15","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/16","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/17","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/18","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/19","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/20","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/21","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/22","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/23","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/24","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/25","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/26","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/27","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/28","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/29","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/30","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/31","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/32","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/33","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/34","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/35","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/36","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/37","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/38","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/39","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/40","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/41","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/42","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/43","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/44","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/45","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/46","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/47","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/48","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/49","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/50","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/51","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/52","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/53","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/54","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/55","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/56","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/57","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/58","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/59","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/60","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/61","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/62","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/63","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/64","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/65","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/66","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/67","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/68","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/69","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/70","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/71","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/72","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/73","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/74","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/75","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/76","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/77","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/78","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/79","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/80","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/81","
