Here is a typical Honda Accord drive cycle. Driving your Honda Accord in the manner below should make the required Emission Monitors "Ready". Before you start the Drive Cycle make sure your Honda Accord's fuel level is between 1/4 and 3/4, otherwise the EVAP test won't run. Make sure to obey all traffic laws while performing the drive cycle.
1. Begin by idling the engine while 2 1/2 minutes. Next idle for another 2 1/2 minutes with the A/C compressor and rear defroster on and while the transmission is in Drive (D); only of automatic transmission. This part of the drive cycle checks the oxygen sensor heater circuits, air pump and EVAP purge system.
2. Turn the A/C compressor off and rear window defroster off and accelerate to 55 mph at half throttle. During this step the OBDII system checks for ignition misfire, fuel trim and EVAP canister purge.
3. Hold at a steady state speed of 55 mph for 3 minutes. The computer will now be testing the EGR system, air injection pump, O2 sensors and canister purge.
4. Decelerate to 20 mph without braking (or depressing the clutch). Once again the computer system will check EGR and purge functions.
5. Accelerate back to 55 to 60 mph at half throttle. During this step the OBDII system will look for misfires, fuel trim and EVAP purge.
6. Hold at a steady speed of 55 to 60 mph for 5 minutes. Catalytic converter efficiency, EGR flow, ignition misfire, fuel trim, EVAP system and oxygen sensors operation will now be checked.
7. Decelerate to a stop without braking (or depressing clutch). The OBDII system will complete the drive cycle at this point.
We recommend completing this drive cycle at least twice in order to ensure all required parameters have been met.
