I need to know the drive cycle for my 2001 elantra .I had code PO105 that is fixed but it wont reset

Gitit scand n correct issue..wontpass w lite on

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.

check for vacuum leaks in the small rubber hoses.

Check the level in the ******. Make sure that oil is there and topped up if necessary. It should be on the upper marks. Good luck.

you would need to clear the codes with a scanner. or fix the problems relating to the light being on, and cycle the codes out by driving the car. if you lack patience, clearing the codes is faster, though you still need to go through the cars "drive cycle"

this means your catalytic converter is no longer doing wut it supposed to! needs replaceing ! u can drive the car! but get it done asap

if u want to turn off the abs light on dash will need to have car scanned for problem most auto stores scan for free fixing problem will reset trouble light ---if u want to drive with out abs braking system[really not advisable] u can pull the abs fuse which will give u a trouble light on dash and in some cases[dont know what year matrix u have] the brake light and if u have traction control that trouble code as well

NEED check engine light code. just shooting in the dark, but it could be your throttle position sensor or the gear indicator (some times called neutral safety switch). to try and reset it (works on some models) when its doing this (giving you grief). pull over to the side of the road when safe and shut off the car (put in park) then press the accelerator all the way to the floor for 30 seconds. then start the car (take foot off of accelerator first) might cure the problem. engine error code would be most helpfull

Satlaan: You need an odb2 scanner to extract the trouble codes. If you don't have one you can buy one for around $30 from most auto part stores. Alternatively, some auto part stores (Auto Zone for example) will read your trouble codes for you, for free. The trouble codes could be anything from a loose gas cap to a misfire, without the scanner there is no way to know.

Rashidas: How did you fix the speed sensor? This is not the speedometer cable that bolts to the transmission, but a separate sensor inside the right side front wheel behind the brakes.

This AllExperts.com post explains it pretty well.

Don't just assume it is the sensor though,, that wiring gets beat up by all the **** you drive over, so look at the wiring carfully.

Hope that helps,

I had an Issue like that on my 2001 Hynudai Elantra GLS and it ended up needing to have the Ignition coil replaced.
