Reset maintanice light - 2007 Toyota Corolla

lift the bonnet and look?

try disconnecting+ battery cable for a few minutes

PO300 mu;ti cyclinder misfire can be many things Low fuel pressure or clogged fuel filter. Worn sparkplugs, need of major tuneup. If the car doesn't run bad conpared to last week when it did'nt have the missfire it may have missed just long enough to set the code. Engine starting cold and the valves and other engine parts not warming up fast enough not to stumble. The oil change being overdue can make this happen.. If it seems to run as good as anyways and basic maintanice is up to date reset the computer ( clear codes). Drive the car and try to see when and if the light comes on. Running real low on fuel, and running real short rips can cause fuel build up in the oil that can make it stumble as the engine oil does come to operating temperture.

getting enought room to get it out is the problem. 4 thought bolts hold it on and the linesets are held on with one bolt for each line. don't forget to remove the freon first as you can hurt yourself. corse the belt needs to be removed. The easiest way to get enough room is to take out the raditor so you may as well clean it and do a good cooling system maintanice while your in there

The power chips work fine but you have to think why did'nt the Toyata peaple do it first? The reason is the car might not be able to pass emission tests durability test fuel milaage test. The chips are designed to help retune the engine for other improvements like a cold air intake( more noise) open muffler or converter ( more noise and polution) more power has it's own problems. The whole drivetrain was designed to have this much power as you increase the power you alsoo need to improve the brakes tires shocks as a bigger more powerful truck has. Toyatas last a long time with very few problems. I you can afford troble and stey up the maintanice of all the systems, it can be fun, but may cost as much as getting a truck that has more power to begin with.

TURN THE IGNITION KEY TO RUN WITH THE ENGINE OFF.FULLY PRESS AND RELEASE THE ACCELERATOR PEDAL THREE TIMES WITH IN FIVE SECONDS.YOU HAVE TO DO THIS MORE THAN ONE TIME.ITS NOT GOING TO RESET FIRST TRY BUT DO THIS PROCEDURE.UNTIL THE CHANGE ENGINE OIL LIGHT WILL FLASH WHILE THE SYSTEM IS RESETTING.TURN THE KEY TO OFF.WAIT A FEW SECONDS.START CAR UP TO SEE IF CHANGE OIL LIGHT COME BACK ON.IF YES YOU HAVE TO TRY THE RESET PROCEDURE AGAIN.

A Transmission MAY be able to Make Adjustments to Correct this Otherwise sounds as if it is on its way OUT

This is tripped on by an odometer count reminding you its time for service. Technicians will reset light and it will trip once again in 5k miles

Hi to reset the oil life monitor

The same thing happend to one of my wranglers, a 95 yj 4cyl 2.5 liter. The "Aisin AX-5" is the transmission that jeep used on the yj and tj 4cyl and 83 cherokee and up 4cyl, and the "Aisin AX-15"was used on some of the 6cyl models. Both are a "light duty" transmission according to the transmission manufacturer. As everyone knows, A jeep is no light duty vehicle, the shifting slider, a fork like item slides the gears back and forth over the drive and output gears to change the gears. and with heavy use or lack of maintanice they can break, they also can break cause of the cheap casting they used in the tranny. Other problems happen in those trannys too. The only thing is to tear the tranny apart and find out what failed and replace. I did this on the kitchen table ofer a day off. being the up own an early 90s yj, If you are one who doesn't work on their own car, I would find a good garage that is good with jeeps, they are not to expencive to fix, and when they are taken care of, will be a joy to own.
I hope this helps, Jeep ownership is a great thing.
