resetting a computer program is done with a scanner or fault code reader
any thing else is a waste of time
has any shop bothered to read the fault codes properly
I think you mean drive cycle not complete.
Generally the van needs to be driven 50-100 miles at both city and highway speeds. The distance needs to start when the engine is at operating temp, and the speed needs to vary including stop and go city. It does not have to be all in one trip but the engine must be warmed up first.
Both of these monitors won't run until the oxygen sensor monitor has run. The oxygen sensor monitor won't run if an Engine Coolant Temperature (ECT) sensor Diagnostic Trouble Code (DTC) is stored. So, did you replace the errant coolant temp sensor? I take it you did and reset the codes. But you need to check the codes again and see if there are any that returned or are pending. A pending misfire code will not allow the oxygen sensor monitor to run. (Pending codes will not turn on the check engine light.)
This information is from Haynes Techbook "OBD-II" (No. 10206) Chapter 6, p. 14-16 (Highly recommended reading!)
Putting miles on them wont reset the computer. It is how many times you cycle the key on and off. And they will only reset if the problem was fixed. I don't know how many times yours has to be cycled, but some vehicles are up to 100 times. Hope this helps.
Drive cycle has to do with normal everyday type of driving. So many stops, so many miles, fast driving, slow driving. My car went thru a drive cycle in about 38 miles on my way to work. My daughters took 3 days and about 78 miles. So just drive it like normal.
No tune up required until 100,000 miles. If you are at that mileage change the spark plugs. Change the fuel and air filters. Inpect the brakes, exhaust system and suspension. Change the brake fluid and transmission fluid. Change the engine coolant.
ok well 110 miles resets most off them got one to go
