Well if the engine light is on, it usually means there is a DTC (diagnostic trouble code). You need to have it checked out and find out what the problem isthat threw thecode and how to fix it, or it will just pop up again and again. But if you just want it to go away temporarily, all you need to do is disconnect the battery completely (positive and negative cables) and wait about 3 minutes for the computer to discharge and reset. NOTE:that after doing this, the engine is going to run a little rougher than your used to as it has been completely reset (as if it was brand new) and has to relearn itself all over again. Hope that helps. http://www.rav4world.com
maintenance with engine
Reset the Check Engine Light by disconnecting the battery for about 10 minutes.
To reset the reminder light on a Toyota, you need to turn the ignition key forward without starting the vehicle. You then need to pump the gas peddle 3 times within 10 seconds and it will reset the reminder light.
You need a code reader to reset it or go to a shop and get it reset. Average $20 however, if you don't fix the problem why the check engine light came on in the first place it will only come back on again.
You can reset your engine service light by holding in the scroll button. Hold the button in until the engine oil life goes to 100 percent. The engine service light will go off.
no because both of them are built for a certain engine
3 litres
The 2.4 liter 4 cylinder engine in a 2005 Toyota Rav 4 has a timing CHAIN
The block heater is located near the engine on most cars. This is true also for the 2003 Toyota Rav 4.
the 2.0 L 4 cylinder is not an interference engine
Stop by AutoZone and ask them to use their code reader because officially they are not allowed to reset trouble codes.
check the gas cap... usually if you "lost" yours and/or it isn't tight this could cause the check engine light to come on
