Hello Lytten.

It may take a while yet to run the tests.
If all systems are functioning normally it will eventually reset.
Some of the tests need very specific parameters in order to test themselves.
Air temperatures, fuel levels, highway runs, stop and go traffic for some examples all come into play.
Drive it for a while more, you will find it will be OK.

Thank you for using FixYa.

Why is oxygen sensor not ready, if I replaced it already, and ran the car for 50 miles?


First--- you look at scan tool data & test parts
BEFORE you replace any

There are many O2 Codes & most sensors have
several things, in a trouble chart or trees, to follow,
to find problems

Evap System, is not the same system, as the Oxygen
Sensor Monitor is on--different codes to work on,
different problem

You have 8 Monitors

So get all your codes & find out what they are & component
test

OBD Codes have nothing to do with changing parts

They are only an indication of an out of range parameter

You need to find a new shop that can actually diagnose
a vehicles evap system & the emission monitors

You can not do that without professional tools & knowledge

Don't know how many times you need to be told that

The shop you went to isn't doing anything apparently

You have problems to find & resolve & no one else will
give you a different answer, if they even work on vehicles,
or have knowledge of the obd systems & only the pros have
the test equipment needed

I tried to get a sticker and failed because it stated that 2 (02)sensors, catalyst and evap were not ready on my 2001 saturn sw2. How do I fix this? I have been over 300 miles and have failed twice.w


It is not something you fix, the system self tests after any time the battery is disconnected or the system reset with a scanner tool. Drive it until it clears, take about 20 miles of mixed driving, idle time, freeway, moderate speeds like in town. Gas tank must be at least 3/4 full for the test to complete. This is known as an OBD2 drive cycle. If you had a check engine light and it comes on again then you did not fix the problem.

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

How many miles do i need to drive to have the computer re-ready to accept obd codes?


200 miles is more than enough. p0420 is a cat code meaning the cat in the exhaust is not doing its job. you need to make sure there are no exhaust leaks before the downstream (last one) o2 sensor. if you can get all but 1 monitor to set without the check eng light coming on, you will pass pa emmissions.

Can't get my 96 chev s-10 to pass inspection due to Not ready codes. I recently change the battery and have driven the veh about 200 miles. Autozone checked and said it was all good but the state...


Here is the drive cycle procedure for that vehicle, and let me know if you require any further assistance.


Running an OBD-II Drive Cycle

The purpose of the OBD-II drive cycle is to run all of the onboard diagnostics. The drive cycle should be perfomed when any trouble codes are erased from the PCM or if the battery was dis-connected. Performing the drive cycle will reset the monitors so that any further trouble codes can be detected.

The OBD-II system drive cycle begins with a cold start with the coolant temperature below 120 degrees F. and the coolant and the air temperature sensors within 10 degrees of each other. (The ignition key must not be "on" or in the "Run" position until the cold start or the heated O2 sensor diagnostic might not start)

1. As soon as the vehicle starts up, idle the engine in drive for two and a half minutes with the AC and the rear defrost on if equipped with a rear window defroster. The OBD-II will check the O2 sensor circuits, the air pump, and the EVAP purge.

2. After the two and a half minutes turn off the AC and the rear window defrost, and then accelerate to 55 mph at half throttle. OBD-II checks for any ignition mis-fires, fuel trim, and canister purge.

3. Hold steady at 55 mph for three minutes. OBD-II monitors the EGR system, the air pump, the O2 sensors and the canister purge.

4. After the three minutes decelerate down to 20 mph without using the brakes or the clutch. OBD-II checks the EGR and the purge functions.

5. Accelerate back up to 55 mph at half throttle. OBD-II checks for mis-fires, fuel trim, and purge functions again.

6. Hold steady at 55 mph for five minutes. OBD-II will monitor catalytic converter efficiency, for any mis-fires, EGR function, fuel trim, O2 sensor operation, and purge functions.

7. Decelerate to a stiop without using the brakes or the clutch. OBD-II makes a final check of the EGR system and the canister purge functions.

OBD II Test Shows a Malfunction in the MAFs (Massive Air Flow) S


The O2 sensor located on the exhaust system must be checked.
Sensor and wiring must be tested using a multimeter.

Same thing for the MAF sensor located on air intake.
