Is your 2017 Honda Ridgeline failing emissions tests due to “not ready” monitors? Understanding your 2017 Ridgeline Obd2 Readings is essential for ensuring your vehicle is ready for a smog test. Often, OBD-II readiness monitors need to be properly set before your vehicle can pass. A specific OBD-II drive cycle can facilitate this process.
To perform an effective OBD-II drive cycle on your 2017 Ridgeline and obtain accurate OBD2 readings for monitor readiness, adhere to the following steps, beginning with a cold start (coolant temperature below 122 degrees Fahrenheit and coolant and air temperature sensors within 11 degrees of each other):
NOTE: Ensure the ignition key is not turned on prior to the cold start, as this may prevent the heated oxygen sensor diagnostic from running.
-
Immediately after engine start, idle the engine in drive for two and a half minutes with the air conditioning (A/C) and rear defrost activated. This step allows the OBD-II system to check the oxygen sensor heater circuits, air pump, and EVAP purge system.
-
Turn off the A/C and rear defrost, then accelerate to 55 mph at half throttle. During this phase, OBD-II assesses for ignition misfire, fuel trim, and canister purge. Maintain a steady speed of 55 mph for three minutes to enable monitoring of the EGR system, air pump, oxygen sensors, and canister purge.
-
Decelerate (coast down) to 20 mph without applying the brakes or depressing the clutch. This action allows OBD-II to check the EGR and purge functions.
-
Accelerate again to 55 to 60 mph at half throttle. OBD-II will re-evaluate misfire, fuel trim, and purge functions.
-
Hold a steady speed of 55 to 60 mph for five minutes. This extended period allows OBD-II to monitor catalytic converter efficiency, misfire occurrences, EGR operation, fuel trim adjustments, oxygen sensor performance, and purge functions.
-
Decelerate (coast down) to a complete stop without braking. OBD-II performs a final check of the EGR system and canister purge.
By diligently completing this OBD-II drive cycle, you can significantly increase the likelihood of setting your 2017 Honda Ridgeline’s readiness monitors. This ensures accurate OBD2 readings, preparing your vehicle for successful emissions testing and confirming the proper function of critical emission control systems.
