SOURCE: check engine light/2003 toyota CE

have you had a diagnostic code check? if not i'd start there. it sounds like it might be a oygen sensor, but before spending money on it, it really should have a diagnostic test to tell you exactly whats causing the problem.

SOURCE: 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.

SOURCE: How far to drive for drive cycle?

I dont think it matters how far you drive as long as it gets completly warmed up and then gets completly cooled down.
It sounds like you already know this but But for other readers benifit I will add that there are some details that can make the process quicker.
this only pertains to 1996 on up vehicles that the check engine light is NOT illuminated.
When preparing for emissions tests after unhooking your battery, there are readyness tests that have to be completed before your truck is ready to be tested.

  • Basicly in a nut shell, all they do at the emission station is to make sure that your check engine light is not coming on because of any issue.
The way they check this is observe the light before and after they start up your vehicle. If it goes out after starting then your good.
except for one thing, they hook up to your trucks computer and see if your computer has been reset. if so they confirm that your truck has ran its readyness tests.
Thus if there were any problems then the light would be on.
Then it dosnt pass
  • If your readyness tests are not complete and your light is off, then they will send you away and tell you to drive your truck for a few days and then come back. Hopefully then the readyness tests will be done
You can expodite the process by driving in certian patterns for different tests.
The pattern that I have found that works the best to complete the most tests, is
  • Start your truck and let it warm up completely,
  • then drive the truck at a steady speed at 40 to 50 mph for 5 miles
  • coast down to 30 then back up to 50
  • then coast down to 30
  • When its convenient stop and let the truck idle for two minutes,
  • Then turn it off for at least 5 seconds. thats it.
Where I live there is traffic and it is very difficult to find a time or place to drive it at these speeds for that far.So I just follow it the best I can.
I use this dirve pattern all the time and 90% of the time It will run the tests it needs to pass.
If you havent unhooked your battery or reset your computer recently, and your check engine light is not on then you dont have to worry about any of this information, your car should pass emissions test.

Not ready means that the engine control computer has not completed what is called a drive cycle self test, to do this drive cycle and clear the system asap you need to follow the instructions at the link. Note that during the drive cycle you may get that fault code and check engine light again if the problem you mentioned is still present. How to Perform Basic Drive Cycle

What are the drive cycle steps to reset the system so we can get an emissions test done?

Sometimes it's not just one sensor that is faulty or worn and won't activate the engine light until one sensor is replaced to clear the light. Some vehicles have more than one sensor( such as 2 or 3 catalytic converters could have an oxygen sensor for each converter). I would have the dealership do another scan to locate which sensor is activating the check engine light (CEL.) I imagine they warranty their work for the initial work done recently if that's the problem. Most auto part stores will run a scan for free to detect what part (sensor) is engaging the light.

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.

Reset check engine light

The light could be blinking because you haven't driven it enough for it to register. Drive it for awhile and check again. If the light still blinks, you will need to know what code it has.

Take it to autozone or another place like it and have them read the codes and tell us what they are.

A drive cycle is a test that the on board computer performs while you drive the car to prove out all the systems on the car that control tailpipe emissions, if it finds a problem it will trigger a check engine light and and the drive cycle will not complete. The correct name of this is the "OBD2 ELECTRONIC ENGINE CONTROL DRIVE CYCLE TEST". "OBD2" is short for On Board Diagnostics generation 2. The test is just driving the car at various speeds, stop and go traffic and idle time, make sure you have at least 5 gallons of gas in the tank as well. Many folks disconnect the battery to clear a Check Engine light when a smog is due, this resets the computer (known as the PCM) and then you must complete a OBD2 drive cycle, which of course will turn the Check Engine light back on.

Battery was disconntected to replace a connector now computer is 'not ready' and failed emissions test. driven it over 600 miles since then. Tried to follow steps to complete a 'drive...

Do you have a service engine light on or does the smog station tell you that the monitors are set?
A drive cycle won't clear a service engine light if the reason for it was not fixed. Normally a drive cycle or a 25 or so mile drive will be enough for the PCM to run through its test, and if all is well, clear the monitors.
Now some shop scanners and code readers can clear the monitors. Actron is one of the code readers that I know of that will clear monitors (the newer models. older ones did not). They are about $75 for the basic code reader and may be a worthwhile investment for the do it yourselfer.
Auto Zones also have code readers and if theirs is capable may do it for you. Though if you're in California I have heard they don't do that any longer due to people getting codes cleared just before a smog test without fixing the issue first.

Land rover 2003 check engine light on. Drive cycle needed

Clear the codes per factory specs, you must drive the car for at least a week normal driving in order for the computer to reset itself to have all sensors in ready mode to be scanned for emissions testing or it will fail emissions due to the computer sensors showing NOT READY MODE, which the mechanic may not tell you about in order to sell you services you don't need.
