99 Taurus drive cycle without scan tool

I have a 99 Ford Taurus that won't pass AZ State required emissions test. I have tried the drive cycle in the owners manual and it still wouldn't pass emissions. They said the drive cycle wasn't complete. I went online to find the definitive way to complete the drive cycle. What I have learned is you need a scan tool. My question is this, "Can I complete a Drive Cycle with out using a scan tool? Pleeeease Help!

SOURCE: What is drive cycle miles to make ready emission

a drive cycle is not measured in miles driven but in the type of driving done, here is a ford drive cycle procedure to clear the not ready code.

Ford Motor Company Driving Cycle Description of OBDII Drive Cycle
The following procedure is designed to execute and complete the OBDII monitors and to clear the Ford P1000, I/M readiness code. To complete a specific monitor for repair verification, follow steps 1 through 4, then continue with the step described by the appropriate monitor found under the "OBDII Monitor Exercised" column. When the ambient air temperature is outside 4.4 to 37.8°C (40 to 100° F), or the altitude is above 2438 meters (8000 feet), the EVAP monitor will not run. If the P1000 code must be cleared in these conditions, the PCM must detect them once (twice on some applications) before the EVAP monitor can be "bypassed" and the P1000 cleared. The Evap "bypassing" procedure is described in the following drive cycle.
The OBDII Drive Cycle will be performed using a scan tool. Consult the instruction manual for each described function. NOTE: A detailed description of a Powertrain Control Module (PCM) Reset is found in this section, refer to the table of contents.
Drive Cycle Recommendations:

  1. Most OBDII monitors will complete more readily using a "steady foot" driving style during cruise or acceleration modes. Operating the throttle in a "smooth" fashion will minimize the time required for monitor completion.
  2. Fuel tank level should be between 1/2 and 3/4 fill with 3/4 fill being the most desirable.
  3. The Evaporative Monitor can only operate during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to minimize "fuel slosh".
WARNING
STRICT OBSERVANCE OF POSTED SPEED LIMITS AND ATTENTION TO DRIVING CONDITIONS ARE MANDATORY WHEN PROCEEDING THROUGH THE FOLLOWING DRIVE CYCLES.

For best results, follow each of the following steps as accurately as possible:

Some times it takes several days to reset the drive-cycle = Starting from cold state, different speeds for a certian distance, EVAP from cold condition and time. If the PCM dosen't get the proper readings from the sensors it won't reset untill it does. If you keep getting an " incomplete" on a system, then there's a problem with that system and you will have to find and repair it.
Give it a few days of running varried trips.

What is the drive cycle for a 2003 Nissan Sentra SE?

Take extra caution while performing dirve cycles on public roadways. Drive cycles can be difficult to follow under normal driving conditions. Begin by: - Start the engine. Idle the engine in drive for two and a half minutes with the A/C and rear defroster on. - Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. - Hold at a steady speed of 55 mph for three minutes. - Decelerate (coast down) to 20 mph without braking or depressing the clutch. - Accelerate back to 55 to 60 mph at ¾ throttle. - Hold at a steady speed of 55 to 60 mph for five minutes. - Decelerate (coast down) to a stop without braking. If all other emissions systems are functioning properly, completing the drive cycle above will set the "readiness flags" required to pass the smog check. It will not hurt to perform the drive cycle 2 or 3 times before the smog test.

I replaced the alternator on my 1999 Audi A6 with 2.8 engine. Now the check engine light is on. Was not on prior to the repairn. How do I correct?


Instructions on How to Turn Off The Check Engine Light:
Step 1. If not using a scan tool, locate your vehicle's battery. Disconnect the 12v positive cable (red wire) from battery terminal (+). Leave it disconnect for 5 minutes. While the battery is disconnected, cycle the ignition switch to ON position 3 times. If using a scan tool to turn off the check engine light, follow manufacturers directions. You will need to find your vehicle's OBD II Data Link Connecter (DLC) and connect your scan tool to the DLC, then follow the steps indicated on your scan tool or scan tool manual.

Step 2. Insure ignition switch is OFF. Reconnect the battery 12v positive cable (red wire) to battery terminal (+).

Step 3. Cycle ignition switch to ON position and wait 1 minute, then start your vehicle. Check Engine Light or Service Engine Soon Light should be reset and turned OFF.

Step 4. Drive your vehicle for one week under normal driving conditions. During this period the emissions computer is gathering data and re-learning your vehicle's emissions components and systems. The emissions computer OBDII (on-board diagnostics) system must complete at least one drive cycle (in some cases two or three). A drive cycle is a sequence of internal tests which the emissions computer runs while your vehicle is being driven. This insures all emissions systems are functioning properly. Proper "readiness flags" are set as the computer completes it's cycles. Test cycles are unique to a vehicle. Certain cycles run under very strict parameters, and may require extended driving time to trigger on. Cycle data and readiness flag information is available through your dealership's service department. The data vary widely.

What is the drive cycle of a 2003 grand am

The drive cycle is a series of conditions that you drive a vehicle to prepare the emissions systems for an emmisions test.

the drive cycle that is most common to GM vehicles is the following;

1. cold start vehicle and allow to warm up to driving temperature, then set a load on the engine, ie. turn on radio and A/C MAX and headlights.
2. reverse vehicle for approx. 15-20 ft.
3. from a stop, drive vehicle at 35mph @ 25% throttle for 15min
4. allow vehicle to slow to a near stop without using hte brake pedal.
5, begin driving vehivle again 45mph @ 50% throttle for 15-20 min.
6. check for emissions status and test.

***OBDII vehicles (95-99) can have up to (2) two emissions monitors at unready status for PA and can sucessfully submit a "pass" status.
vehicles that are 1988 (OBDI) are emissions exempt.

Battery was out of 99 ford taurus for 2 month now cant get reading from obd told to drive car 4/5 days how many mile do i need to dive car to reset obd for emission test

It has nothing to do with Miles and EVERYTHING to do with Drive Cycles.. There are certain things that must be tested. Within the first 10 miles, generally speaking you are going to complete the Drive Cycle requirements for ALL the tests except for 2-3. The EVAP/ O2 normally the last ones to get cleared.

Your Vehicle is a 1999 which means that you can pass the I/M test with 2 lights "NOT READY". The EVAP is going to take longer than a few miles, you must fill up your car with fuel above the 3/4 mark and then it has to go below I believe it is 1/2.

But if there are 2 Not Ready's... it will pass

NO it's not bad. If any scan tool reads it and the mechanics scan tool wont' then there is a problem with the mechanics scan tool. Some scan tools require a different chip in them to read different cars. Try another mechanic.

My 2000 Lincoln town car has been diagnosed as requiring 02 sensor replacement. Car has 220,000 kilometres on it. Can I continue to drive without replacing the sensor?

Yes you can still drive it. However your gas mileage will drop . Also it wont pass the smog/ emissions test if your state requires one.

On-board computer not ready for emission inspection 02 ford taurus. replaced battery 1 month ago

This is the biggest flaw in emissions testing. It takes 4 tanks of fuel and 1000 miles of wasteful driving to reset the computer on the FORD TAURUS (I've got a 2000). So much for pollution control!

EMISSIONS REJECT, AGAIN, AND AGAIN....AND AGAIN!!!

If it is not passing because monitor is not completed and there are no trouble codes.
Start from cold engine with no more than 3/4 tank of fuel and more than 1/4. Drive it about 25 miles with at least 2 minutes of steady speeds between 35-45 mph and also the same at 50-65 mph.Then make several stop and goes,pausing about 20-30 sec when stopped.
If you turn the engine off before the monitors complete you must go thru a 6 hour cool down cycle before it will try and complete again. Then stop by an Autozone or some place that checks codes for free and have them check it and make sure no codes are stored in memory and the P1000 code has cleared. If it has cleared you should be good to go then. Plus this will make sure that it is not an issue with their inspection machine linking up with your vehicle. The only other problem it may be is if you are loosing the keep alive memory when you shut down your vehicle.That would be fuse 19 (15amp) in the underhood fuse panel.
