SEF357W SEF799W COMPONENT INSPECTION EVAP control system pressure sensor 1. Remove EVAP control system pressure sensor with its har- 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 5. Check output voltage between ECM terminal q 92 and ground. Pressure (Relative to atmospheric pressure) Voltage (V) 0 kPa (0 mmHg, 0 inHg) 3.0 - 3.6 −9.3 kPa (−70 mmHg, −2.76 inHg) 0.4 - 0.6 CAUTION: I Always calibrate the vacuum pump gauge when using it. I Do not apply below −20 kPa (−150 mmHg, −5.91 inHg) or 6. If NG, replace EVAP control system pressure sensor. I Never apply force to the air hole protector of the sensor, I Discard any EVAP control system pressure sensor which GI MA EM LC FE AT PD FA RA BR ST RS BT HA EL IDX TROUBLE DIAGNOSIS FOR DTC P0450 Evaporative Emission (EVAP) Control System EC-325 |
