DTC NO.
DETECTION ITEM TROUBLE AREA 13 Open or short in front evaporator temperature sensor circuit Front evaporator temperature sensor Harness or connector between front evaporator temperature sensor and A/C amplifier A/C amplifier WIRING DIAGRAM INSPECTION PROCEDURE PROCEDURE CHECK AIR CONDITIONING AMPLIFIER 1. (a) Remove the A/C amplifier with the connectors still connected. (b) Turn the ignition switch ON. (c) Measure the voltage between terminals FRTE (A48-16) and FRSG (A48-18) of the A/C amplifier connector at each temperature. Standard voltage: 2.0 to 2.4 V at 0°C (32°F) 1.4 to 1.8 V at 15°C (59°F) HINT: As the temperature increases, the voltage decreases.
However, if DTC 13 is displayed, check and replace the A/C amplifier. OK REPLACE AIR CONDITIONING AMPLIFIER NG INSPECT FRONT EVAPORATOR TEMPERATURE SENSOR cardi 2. REPLACE AIR CONDITIONING AMPLIFIER
