Question about Cars & Trucks
Posted by Anonymous on
PO133 indicates that your front oxygen sensor is not controlling the engine properly .. thats usually a bad oxygen sensor .... in some cars thats easy to change. you could do it if you have any mechanical abilities .. in other cars its nearly impossible, it takes special tools and patients beyond human .. hopefully yours is one of the easy ones .. the part itself might be less than a hundred bucks at an auto parts store but more than that at a dealership . other things that can cause this ... if the wires going to the oxygen sensor are damaged .. and if there is a significant exhaust leak (you should hear that) .. usually changing the oxygen sensor will fix the problem ..it has wires going to it and it screws into the exhaust system somewhere between the engine and the catalytic converter. if you give your auto parts store the make, model, year and engine size of your car then they can probably show you where to find the sensor .. if you are not mechanically inclined then find a mechanic with a good reputation forget lowest price .. i find that often the auto parts store can recommend someone if you ask ..
