How do I do a code check on my rav 4 2003 - 2003 Toyota RAV4

have car scanned for codes

Si nota que se ha encendido la luz de trac de su Toyota Rav 2011, esto significa que hay un problema con el sistema de tracci?n. Primero, aseg?rese de que el sistema de tracci?n del veh?culo est? activado. Si est? activado, es posible que haya un problema con el sistema el?ctrico del veh?culo, con los componentes del motor, con los sensores del tr?nsito, con el fluido de frenos o con la computadora del veh?culo. Para solucionar el problema, debe contactar a un mec?nico profesional para que pueda diagnosticar el problema y luego realizar los reparos necesarios.

Do you have the dash light dimmer control turned down by chance?

The flashing check engine light means there is a serious problem with the performance of the engine. You need to get the computer scanned for trouble codes next.

I doubt it.
Did you check the computers for trouble codes ?

In my experience, you need to contact the Toyota dealer for these. They should have a record of them--they keep track of them by the VIN

Strip the plastic off the head of the key. The key code should be under that part stamped into the metal keys head

A/F Sensor Heater Circuit Malfunction (Bank

You most likely have a bad Air fuel sensor bank 1 sensor 1.

Unless your computer in your car is faulty... the check engine light came on because it, or one of your vehicle's many sensors detected something within your vehicle was not operating under preset factory conditions. Fortunately, the error code that was extracted was indeed a cylinder # 1 misfire, which is fairly basic. Could be a bad spark plug, wire, etc. or you may have gotten some condensation inside the plug boot. Your mechanic did indeed clear the code, but drive it for awhile and see if it repeats. Normally with a cylinder misfire, you'll notice a small stutter when you accelerate or idle. If your Check Engine light returns, have the codes extracted once more. If the same cylinder is misfiring, have him replace the spark plug and wires.
