What is the drive cycle for a 2001 Pontiac Sunfire?

Answer 1

There is no drive trace as a whole, however, some monitor cycles are similar and may pass through simultaneouslyCatalyst moniotor: Pre-req: no codes present, IAT between -4 and 176 deg f; ECT is avove 75 deg f; barometric pressure above 72kPa, STFT between -20% and 20 % -Idle vehicle 5 minutes until it is in closed loop -drive 5 min at steady speed above 50 mph -idle 2 min in drive (auto) or neutral (manual) *very stable idle is required to pass this monitor EGR Monitor: Pre-req: no codes present, ECT is avove 75 deg f; barometric pressure above 72kPa 1. Idle vehicle 5 minutes until it is in closed loop 2. Accelerate and drive for 1 min at steady speed above 50 mph 3. coast vehicle down to 20 mph (vehicle in drive or w/ clutch engaged, brake off) 4. repeat steps 2 and 3 four times * the GM egr runs during the deceleration portion of the drive trace Evaporative Monitor:Pre-req: no codes present, IAT & ECT between 45 and 85 deg f: barometric pressure above 75 kPa, fuel tank level between 26 and 74 %; TPS between 9& 35 %; evap solenoid is at 50% pwm within 65 sec of engine run time -Idle vehicle 5 minutes until it is in closed loop -drive 5 min at steady speed between 30 and 40 mph -stop and idle 2 min O2 Sensor Monitor: Pre-req: no codes present, IAT above 32 deg f; ECT is avove 167 deg f -Idle vehicle 5 minutes until it is in closed loop -drive 3 min at steady speed above 50 mph -drive 2 min at steady 40 mph -drive 2 min at steady 50 mph
