Here is the OBD2 emission system drive cycle test procedure.
Engine coolant temp must be below 70c (158f) before starting the engine for either the first or second trip
The fuel level should be less than 1/2 full
First trip:
Start engine, idle for at least 1.5 minutes
Drive 3 minutes, hold b/f schdl: 1.5-2.0 msec, selector lever "3rd" eng rpm 1,800-2,000 A/C switch:ON Hold the recommended b/f schdl range. Allow road speed to vary as necessary.
Drive at 55-65 mph for 1.5 min b/f schdl 2.0-3.2 msec, selector lever "5th" Engine rpm 2,200-3,000
IGN "off" for at least 10 seconds (not more than 5 min)
Dive at 50-60 mph for 3 minutes Selector lever "4th" keep engine speed above 3,000 rpm Allow speed to vary if necessary. Do not decelerate for more than 3 consecutive seconds. A/C switch ON.
Drive at a steady state cruise of 53-58mhp b/f schdl more than 1.8 msec selector lever "5th" eng rpm 2,400-2,600
Downshift to "4th" and decel more than 5 seconds without breaking, then idle for 1 minute.
Drive two minutes b/f schdl less than 2.0 msec Accelerate to 41 mph, decelerate to 34 mph, accelerate to 41mph. Do not completely release the accelerator. A/C switch off.
Idle 1 minute in park or neutral
Drive two minutes Steady state cruise at 31-44 mph. Selector lever "4th" A/C switch OFF. Hold the accelerator pedal as steady as possible. Allow speed to change if necessary.
End of first trip. Turn the key off the begin the second trip.
Second trip:
Start engine, idle for at least 1.5 minutes
Drive 3 minutes, hold b/f schdl: 1.5-2.0 msec, selector lever "3rd" eng rpm 1,800-2,000 A/C switch:ON Hold the recommended b/f schdl range. Allow road speed to vary as necessary.
Drive at 55-65 mph for 1.5 min b/f schdl 2.0-3.2 msec, selector lever "5th" Engine rpm 2,200-3,000
IGN "off" add four gallons of fuel
Dive at 50-60 mph for 3 minutes Selector lever "4th" keep engine speed above 3,000 rpm Allow speed to vary if necessary. Do not decelerate for more than 3 consecutive seconds. A/C switch ON.
Drive at a steady state cruise of 53-58mhp b/f schdl more than 1.8 msec selector lever "5th" eng rpm 2,400-2,600
Downshift to "4th" and decel more than 5 seconds without breaking, then idle for 1 minute.
Drive two minutes b/f schdl less than 2.0 msec Accelerate to 41 mph, decelerate to 34 mph, accelerate to 41mph. Do not completely release the accelerator. A/C switch off.
Idle 1 minute in park or neutral
Drive two minutes Steady state cruise at 31-44 mph. Selector lever "4th" A/C switch OFF. Hold the accelerator pedal as steady as possible. Allow speed to change if necessary. I especially like the part where they want you to add four gallons of fuel. Not three gallons, not five gallons, four gallons. Gotta love those Nissan engineers. ...and of course they state that if the trace is not followed exactly (i.e. you botch the acceleration/deceleration) you have to start all over again from scratch

2002 Hyundai Elantra that says my on board computer is not ready to be tested. Emission results are: readiness- fail, monitor comprehensive- not ready, monitor EVAP not ready,monitor O2 not ready.


Did you recently clear the trouble codes or disconnect the battery? Once all codes are cleared, the computer will not display systems 'ready' until they go through an evaluation cycle. Some of the systems require a certain number of drive cycles before they will display 'ready'. A drive cycle is usually starting the engine from a cold start (based on coolant temperature) and driving until certain conditions are met. I don't know what the requirements are for your car, but my 2003 pickup truck requires more than 10 drive cycles before it will make the O2 sensors and evaporative emissions 'ready'. Most states only require that a certain number of systems are showing 'ready' to pass emissions certification.

I bought a 99 Voyager this week and it failed emmissions because the battery had been removed for a peroid of time and they said I needed to drive it for a while and bring it back. How many miles do I need...


What does "not ready" mean?

A service technician will turn off the dashboard "check engine" light after most repairs. This resets the vehicle's emission system components to "not ready". The status remains "not ready" until the vehicle's computer has had adequate time to review the repaired component. This happens after the vehicle is driven for a period of time established by the manufacturer.

If the vehicle's emissions system status is "not ready" when it is presented at the E-Check station during the initial test cycle, a tailpipe emissions test may be conducted. If the vehicle is transferred to another test type, the vehicle must remain on the different test track until the vehicle passes the emissions test or receives a waiver. For example, if the vehicle undergoes an OBD II test and fails, it cannot be downgraded to a tailpipe test on a re-test; the vehicle must pass the OBD II test.

For initial and subsequent tests, if a dashboard light is on when the vehicle is presented at the E-Check station, the vehicle will fail the test.


How can the vehicle status be made ready?

When a vehicle is driven through its normal drive cycle, the computer reviews the emission control
system and if the vehicle was properly repaired, the system resets itself to ready. A normal drive
cycle includes operation at both cruising speeds and in stop-and-go traffic for up to a couple
weeks. This process should be followed before bringing the vehicle in to be tested.

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 test comes up not ready - can't pass inspection


Under the hood, there is a fuse block. I believe it is on the driver's side of your vehicle. Open that box, and pull the "ECU" fuse. Leave the fuse out for at least 5 minutes. Put the fuse back in, start the car, and let it idle for at least another 5 minutes. Do not drive the car, touch the gas, or even look at the gas pedal for these 5 minutes, as the ECU is remapping itself. This will properly reset the ecu and clear the codes. After this you may drive the car.

Need to do a drive cycle?????


a drive cycle is very complicated and is outlined in the factory emission manual, but here is the short version, u need to do about 20 miles of mixed driving, freeway steady speed, then stop and go and steady low speed, repeated idle times and stop and go, so just drive it in town and on the freeway for a few days and I am sure it will clear the drive cycle test and be ready to pass emission test.
