Check engine light/2003 toyota CE

To turn the engine light off you can buy a car code reader very cheap to buy

The "check engine light" or MIL (malfunction indicator lamp) is telling you that the power train computer is holding a diagnostic trouble code (DTC) in memory. These codes set when a problem with one of the many engine sensors is detected or engine parameters exceed expected programmed limits. A code reader tool is needed to read out these codes and explain the definitions. Most major auto parts stores will read out your codes for free.

Even if your car is running fine, do not ignore this light. In many states, your car will not pass an emissions test with the light on. Many faults that will set codes are related to proper emissions control. But many faults that cause emissions problems also cause poor gas mileage. So if you ignore the light you may very well be wasting precious gas dollars.

Your gas mileage will suffer and if your state requires an annual emission inspection, you will not pass. There is also a possibility that your catalytic converter's life will be shortened because of improper combustion. Ask the dealer if these component are covered under the emissions warranty.

Those lights indicate an issue with ABS or traction control systems. In order to properly diagnose the problem the vehicle's codes will need to be read with a scanner.

Generally speaking there is no danger in driving the vehicle but be aware you may not have functioning traction control and/or ABS while those lights are present.

Hi, I believe their is a TSB for your model. You'll want to check with the dealer because if the ECM needs replacement it should be covered under the emissions warranty. More info @ P0607

sorry if the cat is getting to clogged there is no way around it you most replace it because in time it will effect the performance of your engine.

If you want the check engine light to stay off, make sure that the converter is a direct fit, and not a universal. It should work fine then.

What's the code #?

your car engine may have some hidden problem, suggest you take it to dealer workshop to have you car ECU scan and it will resolve the problem once and for all.

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)
