Check engine light/2003 toyota CE

The light stays on (check engine) can not pass emissions. The check engine light came on, the dealer replaced the catalytic converter. The light came back on, we can reset and drive for a while and the light comes back on. No one seems to know how to correct the problem

Have you had a diagnostic code check? if not i'd start there. it sounds like it might be a oygen sensor, but before spending money on it, it really should have a diagnostic test to tell you exactly whats causing the problem.

Your code 441 is the evap system. Anything from a loose gas cap to a bad vsv on your evap canister, nothing to do with the cat.
You need a scan tool to clear codes. If its not fixed first if will set a fail in that monitor and fail the emission test.
linda_abi, get it scanned to see what the code is.

SOURCE: check engine light/2003 toyota CE

I have a 2005 Camry that has this as a 'feature'. the check engine light comes on after a few thousand miles to indicate that the oil has to be changed. Even if you change the oil, the light comes on unless you reset it. If this is also applicable to your Corolla, check your manual for exact instructions. I always have to look up how to reset it. It is a combination of turning your key in the ignition and holding the odometer reset button. I have to do this every so often. Btw, if this is the cause of your check engine light, it is only meant as a reminder to you, there is nothing wrong with the car.

I have 1998 Toyota Corolla Automatic CE. Check light is on. What is this.


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.

After tightening the gas cap, you will have to drive the car a few 'cycles' before the light goes off. If that doesn't work, have the trouble codes read to find out exactly what is wrong and causing the light to illuminate.

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.

Replaced bank 1 sensor 1 O2 sensor with an OE


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.

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.

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. :)
