Question about 2003 Toyota Corolla

1 Answer

I have a toyota corolla 2003 and recently went for an emissions test and passed. The day after my emission test, the engine light went on. I tried to unscrew and rescrew the gas tank cap, but it didn't work. Is it possible that where I sent my car in for an emissions test, they may have done something to the car that would require further work? I'm always sceptical when it comes to leaving my car at a garage that I'm not familiar with. It was the only garage that was open for emissions test, and Iw as desperate to get it done as my license needed to be renewed.

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.

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.

Why did the catalytic converter on my 2003 Toyota Highlander fail? How do I prevent this from happening again?


I had the same thing happen on a 2003 Corolla. The dealer said one possible cause was too much oil which was blown on to the fins in the catalytic converter causing damage. The catalytic converter is a pollution device so unless you need to pass an emissions test it may not be a factor.

Emission Failed Inspection. Engine light not on.


I've always found the following to help with emissions tests on older cars: Check & replace air cleaner if dirty (difficult to see light through it), Check spark plugs ( will also be good indicator of any bad cylinder so keep them in order of removal) - if any look/measure bad, replace the set. Check engine oil quality & replace if dirty (or you can't remember the last  time it was changed). Dirty oil = higher emissions.
Run engine on higher grade fuel for a few days and during test (better fuel = lower emissions). If o2 sensor is the problem it will set off codes.

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.

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.

2001 toyota corolla check engine light is on. Code reads P420 low threshold. Changed front and rear Oxygen sensors reset the light and drove the car 50 miles and the light came back on. the car will not...


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. :)
