Misfire Monitor and Readiness Code
• This readiness code is always set to available
because misfiring is continuously monitored.
• Monitoring pauses, and the misfire counter resets, if
the vehicle is driven over a rough road.
• Monitoring also pauses, and the misfire counter
holds at its current value, if the throttle position
changes more than a predetermined value, or if
driving conditions fall outside the range of any
related enable criteria.
Fuel System Monitor and Readiness Code
• This readiness code is always set to available
because the fuel system is continuously monitored
during closed loop operation.
• Monitoring pauses when the catalytic converter,
EVAP control system, and HO2S monitors are active.
• Monitoring also pauses when any related enable
criteria is not being met. Monitoring resumes when
the enable criteria is again being met.
Comprehensive Component Monitor and
Readiness Code
This readiness code is always set to available because
the comprehensive component monitor is continuously
running whenever the engine is cranking or running.
EGR Monitor and Readiness Code
NOTE:
• Do not turn the ignition switch off during the
procedure.
• All readiness codes are cleared when the battery is
disconnected or when the PCM is cleared with the
OBD II scan tool or the HDS.
Enable Criteria
ECT at 176°F (80°C) or higher.
Procedure
1. Connect the scan tool to the vehicle's data link
connector (DLC), and bring up the tool's generic
OBD II mode.
2. Start the engine.
3. Drive at a steady speed with the transmission in
D position, 50 62 mph (80 100 km/h) or above
for more than 10 seconds.
4. With the transmission in D position, decelerate
from 62 mph (100 km/h) or above by completely
releasing the throttle for at least 5 seconds. If the
engine is stopped during this procedure, go to step
3 and do the procedure again.
5. If the readiness code is still set to incomplete, check
for a temporary DTC. If there is no DTC, the enable
criteria was probably not met; repeat the procedure.
