MULTIPOINT FUEL INJECTION (MPI)
13A-12
PROCEDURE 1
CATALYTIC CONVERTER MONITOR
DTC
P0421, P0431
Drive cycle
pattern
This monitor [from start to ignition switch "LOCK" (OFF) position] will be completed while
driving the vehicle with the following drive cycle pattern. It will take 20 minutes. You must
complete this drive twice.
NOTE: Vehicle speed and throttle opening angle should be within the shaded range.
Inspection
conditions
• Atmospheric temperature: −10°C (14°F) or more
• A/C switch: OFF
• Condition of A/T: Selector lever D range

Test
procedure
1. Engine: start
2. Accelerate until the vehicle speed is 72 km/h.
3. Travel for 5 minutes or more while keeping the vehicle speed at 72
− 97 km/h.
4. Decelerate until the vehicle speed is within 56
− 64 km/h.
5. While keeping the accelerator pedal opening degree constant, keep the vehicle speed at
56
− 64 km/h and travel for 1.5 minutes or more. (During monitor)
6. Fully close the throttle and decelerate, and keep the deceleration state for 10 seconds.
Then, quickly accelerate until the vehicle speed reaches 56
− 64 km/h. Then, repeat steps
5 and 6, and complete six monitor sessions.
7. Return the vehicle to the shop, then turn the ignition switch to "LOCK" (OFF) position.
8. Confirm that the diagnostic trouble code (DTC) is not output.
9. If DTC P0421 is output, refer to DTC P0421
− Warm - Up Catalyst Efficiency Below
Threshold (Bank 1) .
If DTC P0431 is output, refer to DTC P0431
− Warm - Up Catalyst Efficiency Below
Threshold (Bank 2) .
