The car seems to run good. The egr valve was replaced and the light came back on. The gas cap was replaced also. Anyone else have this problem. The car has 146000 miles on it and is having isssues.

kim_banning84:  you could have hit a bump when you were driving that would have caused it come on, something like a wire might have came out of place but other than that i doubt anything is wrong with it.

sr performance:  i had this problem in my dads mustang its because of low engine oil yeah i know but after fixing things it came back on . . the low oil light is for the brakes(hydraulic) . . check oil level and fuel rail its surely not a breakdown

lila21:  first off you need to change oil, plugs wires,pcv valve air filter and do an octain boost and use seafoam and you can also go to auto zone and get them to do a computer check for you....

John K:  JUST BECAUSE THE LIGHT CAME BACK ON DOES NOT NECESSARILY MEAN YOU HAVE ANOTHER PROBLEM IT MAY BE THAT THE LIGHT CAME ON AS A PRE SET INTERVAL (USUALLY DUE TO MILEAGE) IN WHICH CASE THE LIGHT IS RESET TO OFF AFTER INSPECTION AAMCO TRANSMISSION AND REPAIR SHOP AT 6629 LOMAS WILL DO A FREE DIAGNOSTIC CHECK AND EXPLAIN WHAT THE PROBLEM IS B4 U SPEND ANY $

Nathan B:  Theresa, that light means one of two things, your transmission fluid is low or your oil level is low. My mons car check engine light comes on whenever the oil is hot. And that is on an american car. Generally on foregin cars, it is the transmission fluid that is low when that light comes on. So you should check those two fluids if you want.

king_davis13:  Most of the time the engine light will come on because there is a emissions malfunction somewhere. It could be an O2 sensor or somthing as stupid as a cylinder missfire. The only way to be sure is to have it checked. Auto parts stores like Advance Auto Parts and Auto Zone will check your cars computer and let you know why the light is on for free. And by the way 146000 miles is nothing for a Toyota, My truck has 316000 miles on it and still running like a champ. Hope I have been helpful.
