of rapid cycling, the PCM will use a fixed time If the system does not pass the EVAP Leak Detection Test, the following DTCs may be set: • P0442 - EVAP LEAK MONITOR 0.040 9 LEAK DETECTED • P0455 - EVAP LEAK MONITOR LARGE LEAK • P0456 - EVAP LEAK MONITOR 0.020 9 LEAK DETECTED • P1486 - EVAP LEAK MON PINCHED HOSE • P1494 - LEAK DETECTION PUMP SW OR • P1495 - LEAK DETECTION PUMP SOLENOID ENABLING CONDITIONS TO RUN EVAP LEAK 1. Cold start: with ambient temperature (obtained from modeling the inlet air temperature sensor 2. Engine coolant temperature within: -12° to -8°C (10° to 18°F) of battery/ambient. 3. Battery voltage between 10 and 15 volts. NOTE: If battery voltage drops below 10 volts 4. Low fuel warning light off (fuel level must be between 15% and 85%). 5. MAP sensor reading 22 in Hg or above (This is the manifold absolute pressure, not vacuum). 6. No engine stall during test. NOTE: The following values are approximate T . See TSB 25-02-98 for more detail. A DTC will not set if a one-trip fault is set or if the MIL is illuminated for any of the following: • Purge Solenoid • All engine Controller Self Test Faults • All Cam and/or Crank Sensor Faults • MAP Sensor Faults • Ambient/Battery Temperature Sensor Electrical • All Coolant Sensor Faults • All TPS Faults • LDP Pressure Switch Faults • EGR Solenoid Electrical Faults • All Injector Faults • Baro Out Of Range • Vehicle Speed Faults • LDP Solenoid Circuit FIGURE 6 SECTION 1 When the ignition key is turned to “ON”, the LDP diaphragm should be in the down position and the After the key is turned “ON”, the PCM immedi- ately tests the LDP solenoid circuit for electrical NOTE: If battery temperature is not within temperature calibrations may be different between models. FIGURE 6 SECTION 2 If DTC P1495 is not set, the PCM will check for DTC P1494. If the LDP reed switch was closed FIGURE 6 12 GENERAL INFORMATION |
