WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
- DTCs P0030, P0031, P0032, P0036, P0037, P0038, P0050, P0051, P0052, P0056, P0057, P0058, P0116, P0117, P0118, P0121, P0122, P0123, P0125, P0128, P0131, P0132, P0133, P0134, P0135, P0136, P0137, P0138, P0139, P0140, P0141, P0150, P0151, P0152, P0153, P0154, P0155, P0156, P0157, P0158, P0159, P0160, P0161, P0221, P0222, P0223, P0442, P0443, P0444, P0445, P0446, P0447, P0448, P0449, P0451, P0452, P0453, P0506, P0507, P1271, P1277, P1278, P1282, P1283, P1511, P1516, P1519, P1523, P1526, P1530, P1551, P2100, P2101, P2107, P2119, P2122, P2123, P2127, P2128, P2138, or P2176 not set.
- The condition exists for 8 seconds or no change is detected for 4 seconds.
- EVAP purge solenoid is commanded to a 12 percent duty cycle.
- EVAP vent solenoid is commanded ON.
- Engine is at idle.
- Vehicle speed is zero MPH.
- Engine load is less than 35 percent.
- Ignition 1 voltage is greater than 10 volts.
- Engine Coolant Temperature (ECT) at engine start-up is 40-131°F (4-55°C).
- Intake Air Temperature (IAT) is 40-140°F (4-60°C).
- The long term FT cells learned (if not learned, engine must run longer than 16 minutes and 45 seconds).
DTC P0455 diagnostic runs once during the EVAP diagnostic test once per ignition cycle. If DTC P0455 fails, the ECM will re-run the EVAP diagnostic test from the beginning and must fail P0455 again to set.
If an EVAP diagnostic test is aborted due to changing enabled criteria, the ECM will run the entire EVAP test up to three times per ignition cycle.
