Air Fuel Ratio (A/F) Sensor Monitor and Readiness Code: Procedure
2006 Honda Element EX, 2.4 YH1, StandardSECTION Procedure
- Start the engine.
- Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. During the drive, decelerate (with the throttle fully closed) for 5 seconds. After about 3.5 miles (5.6 km), the readiness code should switch from incomplete to complete.
- Check the readiness codes screen for AIR FUEL RATIO (A/F) SENSOR in the DTCs MENU with the HDS.
- If the screen shows complete, readiness is complete.
- If the screen shows not complete, go to the next step.
- Check for a Temporary DTC. If there is no DTC, the enable criteria was probably not met. Select the DATA LIST Menu. Check the ECT in the ALL DATA LIST with the HDS. If the ECT is lower than 140°F (60°C), run the engine until it is higher than 140°F (60°C), then repeat the procedure.
- Start the engine, and let it idle for 1 minute. The readiness code should switch from incomplete to complete.
- If the readiness code is still not set to complete, check for a Temporary DTC. If there is no DTC, repeat the procedure.
