DTC P1456 EVAP CONTROL SYSTEM EC-1675 [VG33ER] C D E F G H I J K L M A EC 18. CHECK FUEL TANK TEMPERATURE SENSOR 1. Remove fuel level sensor unit. 2. Check resistance between fuel level sensor unit terminals T and E by heating with hot water or heat gun OK or NG OK >> GO TO 19. NG >> Replace fuel level sensor unit. 19. CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR 1. Remove EVAP control system pressure sensor with its harness connector connected. 2. Remove hose from EVAP control system pressure sensor. 3. Turn ignition switch ON. 4. Use pump to apply vacuum and pressure to EVAP control system pressure sensor as shown in figure. 5. Check input voltage between ECM terminal 62 and ground. CAUTION: ● Always calibrate the vacuum pump gauge when using it. ● Do not apply below −93.3 kPa (−700 mmHg, −27.56 inHg) or over 101.3 kPa (760 mmHg, 29.92 inHg) of pressure. OK or NG OK >> GO TO 20. NG >> Replace EVAP control system pressure sensor. 20. CHECK EVAP PURGE LINE Check EVAP purge line (pipe, rubber tube, fuel tank and EVAP canister) for cracks or improper connection. EC-1741, "EVAPORATIVE EMISSION LINE DRAWING" OK or NG OK >> GO TO 21. NG >> Repair or reconnect the hose. 21. CLEAN EVAP PURGE LINE Clean EVAP purge line (pipe and rubber tube) using air blower. >> GO TO 22.
