Engine has been running for more than 9 minutes.
The Intake Air Temperature (IAT) is 0-176°F (-18 and 80°C).
The Engine Coolant Temperature (ECT) is 167-248°F (75-120°C).
The Barometric Pressure (BARO) is more than 75 kPa.
Engine is operating in Closed Loop fuel mode.
Engine speed is more than 1000 RPM for more than 44 seconds.
The ignition voltage is more than 9 volts.
Warm the catalyst (Fully open hood, set transmission in Park (A/T) or Neutral (M/T), set parking brake, ensure engine speed is more than 1500 RPM for 1 minute. Return engine to idle).
Test the catalyst. (Set transmission in Drive (A/T) or Neutral (M/T). Within 5-20 seconds, HO2S 1 should toggle rich above 600 millivolts for up to 7 seconds, then HO2S 1 may toggle lean below 300 millivolts for up to 7 seconds. Using scan tool, check if DTC P0420 has passed or failed this ignition cycle).
