Question about 2006 Toyota Corolla

2 Answers

My check engine light came on, then went off on it's own, now it's back on again. It's a 2006 Corolla with 123,000 miles. The car seems to run fine, though it seems to shift (automatic transmission) a little rough. What can it be? I'm supposed to be going on a trip, should I drive it like that? I'm a student and single parent, and don't have much money.

The check engine light could come on for any number of reasons. You need to go to O'Reillys or a similar parts store where they will lend you a code scanner that you can plug into the car. Usually the plug in is located on the drivers side lower dash area although I'm not sure with a Toyota. Once you have pulled the error code you will have a general idea of what is going on. These codes will not tell you exactly what is wrong but will tell you what sensor is reporting input that is out of spec. Most check engine light conditions are for items related to emissions control. Your problem could be serious; a sensor or part that needs to be replaced or not so serious; gas cap wasn't screwed on correctly. This latter will disappear after a time once the gas cap is installed correctly.

Car shuts of suddenly while driving. Starts back up after 20 minutes.

When the gas-cap is plugged, you build up vacuum in the gas- tank and cause the gas flow to stop.
Use premium gas only, ETHANOL in the mix is attracting moisture/water which is part of the problems.

Flashing check engine light subaru forester

If there is a lot of ice then I would think that the coolant was iced up and the engine overheated as stated . The engine light is there to let you know that something drastic is about to happen to the engine and you should stop immediately , check the oil level and coolant level before driving any distance.

ECS likely stands for Engine Control System. If you have the check engine light on, you should have the car scanned for fault codes.

Check engine light on, auto transmission shifts gears abruptly

It should still be under warrenty Take it to the shop for repairs It is a transmisson problem but many things can cause the transmisson not to shift correctly. Call your service department and ask if you should drive it in or have it towed and do not drive till you have it figured out. If you have a warrenty and continue to drive it will void your warrenty.

Engine check light on

My '06 Corolla's CHECK ENGINE light came on the other day and then went out after about a half hour. It was back on this morning and stayed on, and I noticed that the automatic transmission was shifting a bit more roughly than it ever had before. Took the car to a Toyota dealership immediately. The guy told me that Toyota has had an ongoing problem with the CHECK ENGINE light coming on due to a faulty CPU (car's computer "brain"). This has been affecting models from '05, '06, and '07 according to him. He said Toyota had extended the warranty for this particular part (i.e. the CPU) due to it being faulty. The warranty expires once you reach 80,000 miles, and my car has 87,000 miles on it (yes, I do drive that much for my job!). But the guy at the dealership was kind enough to put in a new CPU for free because I have been a good, loyal customer there. The CHECK ENGINE light is now off and it should stay that way.

Chech engine light came on

Have your engine scanned for free at a parts store such as autozone. Get a code. It may be one sensor or more .my belief is that it is the Crankshaft position sensor or the throttle position sensor. If not , then the EGR, or other valve could be it. but it seems electonic in nature.
