To monitor the system, the number of lean-to-rich switches of upstream and downstream O2S’s is The ratio of downstream switches to upstream switches is used to determine whether the The system must be monitored so that when cata- lyst efficiency deteriorates and exhaust emissions Monitor Operation—To monitor catalyst effi- ciency, the PCM expands the rich and lean switch The test runs for 20 seconds. As catalyst efficiency deteriorated over the life of the vehicle, the switch The MIL is extinguished after three consecutive good trips. The good trip criteria for the catalyst Enabling Conditions—The following conditions must typically be met before the PCM runs the cat- • Accumulated drive time • Enable time • Ambient air temperature • Barometric pressure • Catalyst warm-up counter • Engine coolant temperature • Accumulated throttle position sensor • Vehicle speed • MAP • RPM • Engine in closed loop • Fuel level • Front Oxygen Sensor Response • Front Oxygen Sensor Heater Monitor • Front Oxygen Sensor Electrical • Rear Oxygen Sensor Rationality (middle check) • Rear Oxygen Sensor Heater Monitor • Rear Oxygen Sensor Electrical • Fuel System Monitor • All TPS faults • All MAP faults • All ECT sensor faults • Purge flow solenoid functionality • Purge flow solenoid electrical • All PCM self test faults • All CMP and CKP sensor faults • All injector and ignition electrical faults • Idle Air Control (IAC) motor functionality • Vehicle Speed Sensor • Brake switch • Intake air temperature of the following are conditions are present: • EGR Monitor in progress • Fuel system rich intrusive test in progress • EVAP Monitor in progress • Time since start is less than 60 seconds • Low fuel level • Low ambient air temperature • Ethanel content learn is taking place and the ethenal used once flag is set Suspend—The Task Manager does not mature a catalyst fault if any of the following are present: • Oxygen Sensor Monitor, Priority 1 • Upstream Oxygen Sensor Heater, Priority 1 • EGR Monitor, Priority 1 • EVAP Monitor, Priority 1 • Fuel System Monitor, Priority 2 • Misfire Monitor, Priority 2 NON-MONITORED CIRCUITS The PCM does not monitor all circuits, systems and conditions that could have malfunctions causing JR EMISSIONS CONTROL 25 - 5 EMISSIONS CONTROL (Continued) |
