I have been told to drive more miles to have my monitors reset on my 2019 Ridgeline. Are there any specifics as to driving speeds, highway, city or distance?

 

Catalytic Converter Monitor and Readiness Code
Enable Criteria:

• ECT SENSOR 1 at 158 °F (70 °C) or more.
• IAT SENSOR at 20 °F (-7 °C) or more.
• Vehicle speed above 25 mph (40 km/h).

Procedure: Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. After about 5 miles(8 km), the readiness code should switch to complete.

Air Fuel Ratio (A/F) Sensor Monitor and Readiness Code
Enable Criteria:

ECT SENSOR 1 at 140 °F (60 °C) or more.

Procedure:

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.

Air Fuel Ratio (A/F) Sensor Heater Monitor Readiness Code

Procedure:

Start the engine, and let it idle for 1 minute. The readiness code should switch from incomplete to complete.

EGR Monitor and Readiness Code
Enable Criteria:

ECT SENSOR 1 at 176 °F (80 °C) or more.



Procedure:

Drive at a steady speed with the transmission in D at 50－62 mph (80－100 km/h) or above for more than 10 seconds.
With the transmission in D, 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 step, repeat steps.
