The lambda sensor is located in the exhaust. There are 2, 1 before the catalytic convertor and 1 after. The lambda sensor senses how much oxygen is in the exhaust gases and continually adjusts the fuel/air mixture so that the oxygen level is correct. If the lambda sensor fails and senses the incorrect amount of oxygen it may adjust the fuel/air mixture so that the engine doesnt run properly.

Not sure, but I believe the lambda sensor is the feedback sensor, to determine if the mixture really is right.
On most cars that is the oxygen sensor I believe, and is located in the exhaust manifold or the top of the exhaust pipe.

Service engine, abs, trac off


The service engine light does not affect the abs.You most likely have a broken wire in your abs system which is affected by suspension movement.A code reader which does abs codes will tell you which wheel circuit is turning on the abs light.When there is no abs available the track will turn off.

Lambda sensors, they measure your fuel air ratio being burnt by the engine and addapt the management system accordingly. You will have to put them both back or the check engine light will stay on.

Take your TB to Autozone or a parts store that offers a free check engine light check. All they do is tell you what code your check engine light is throwing. Get this code, and we can help from there.

One of the dash board lights on my 2007 toyota rav 4 won't cut off, what is wrong with it? It's not the oil light


Sounds like the Orange engine light is on? If yes, the 07 Rav 4 is a great car but suffers greatly with Lambda faults. You need the code read to be sure plus there are 4 lambda's on your car.

If it is a Red triangle light staying on then it could be low brake fluid level.

Engine managment light is illuminated and the engine is not running unevenly


its a dummy light and its probly in the emsission system somewhere like a bad O2 sensor or a bad EGR valve PCV valve something vaccuum controlled get it put on a diagnostic machine to find out for sure (the dealership has the best diagnostics machines for your car) also you may want to look over all your vaccuum lines also to make sure that none of them are cracked or leaking because that will make the engine light come on as well.
