2001 Saturn SL2

We have a saturn tech that can tell you more specifically than what I am presenting.

1. Cold Start
In order to be classified as a cold start the engine coolant temperature must be below 50ºC (122ºF) and within 6ºC (11ºF) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.

2. Idle
The engine must be run for two and a half minutes with the air conditioner on maximum and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire and if closed loop is achieved, Fuel Trim.

3. Accelerate
Turn off the air conditioner and all the other loads and apply half throttle until 88km/hr (55mph) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.

4. Hold Steady Speed
Hold a steady speed of 88km/hr (55mph) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.

5. Decelerate
Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 32km/hr (20 mph). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.

6. Accelerate
Accelerate at 3/4 throttle until 88-96 km/hr (55-60mph). This will perform the same diagnostics as in step 3.

7. Hold Steady Speed
Hold a steady speed of 88km/hr (55mph) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.

8. Decelerate
This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.

Keep in mind htat there are over 1000 different drive cycles and this may not apply. Keep the fuel between 1/4 and 3/4 until you get through this or the evap monitor will not run.

Our Saturn Guy says: Drive it for 50 miles without turning off the key in one trip.that usually does the trick to reset the monitors.he may have driven 600 miles total but the question is did he drive it like 50 miles without turning off the key.what i posted for u is the gm drive cycle its almost like what u posted except it doesnt say to turn off the a/c or rear defroster when u drive 55-60 mph for five mins.if i were them i would try both the drive cycle see if the monitors reset if not take a 50 mile drive without turning the key off.i would also check and make sure no new engine codes popped up.sometimes its a pain reseting those monitors but persistance pays off in reseting them.
