    There is an issue with your oxygen sensor. Possibly an open or short leading to that sensor. The sensor it self could be bad however there is long list of possible reasons that don't include the sensor but things that effect it. hope this helps

Its possible that engine fault codes is stored in the compute, I suggest scanned to know exactly what code is there: I could think that your codes are refer at O2 emission or air intake fails.

Keep us updated.

The FIRST step is to scan your engine computer to retrieve fault codes and see why the computer has turned the check engine light on. Without the fault codes, anybody could GUESS what is wrong with your car for weeks and not get it right!

Malfunction indicator lamp in my toyota corolla is on how i fix?

The check engine light also called the malfunction indicator comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

2005 Toyota Corolla check engine light on.Fault code P2716,undefined reading.What does this mean?

Could mean there is one fault causing many faults, example, Air mass sensor, this can cause rough idle and over fuelling so the code reader will just send it back with undefined as there are to many faults to identify as the cause.

Most likely it will be a air fault so check the air sensor first, try cleaning it with carb cleaner, sometimes works. If not get back to me could be 2 other things. although the car will not drive very well if it is any of the other 2.

Toyota corolla 2008 engine light

i think your right about the dealer, the code reader will tell the mechanic what is sending the fault, for him to change the air flow meter then the wiring is bizzare as these are 2 major seperate items and the codes would tell him that. My suggestion, take it to a local mechanic who has a code reader to tell you what the fault is, most mechanics won't charge to have a look. Toyotas are usually a pretty reliable car. Hope this helps, Good luck

2006 toyota corolla - I bought it used in September - didn't get an owners manual with it. A light came on this morning - it looks like a picture of a motor (I think) - is this a check engine light?

If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.
