When the computer throws the code that you need to change the sensor.
bank2 is opposite side of the cylinder 1 and sensor 1 is before catalytic converter so the 1 near the radiator on the top
its located in the back of the motor.
On a 2001 Toyota Highlander with a 6-cylinder engine, the knock sensor is located on the engine block, typically near the cylinder head. Specifically, it can be found on the driver's side, below the intake manifold. Accessing it may require removing some components, such as the intake manifold, for easier reach. Always refer to a repair manual for detailed guidance specific to your vehicle.
It is for the oxygen sensor. There are two, one before the catalytic convertor and one after, this is for the one after it. Follow the exhaust from the side of the engine down and look for something resembling a spark plug in the exhaust pipe.
Usually V6 has a MAF sensor. 4 cylinder does not have it.
Yes, if the vehicle came equipped wiht that option, unless the original spare tire was removed and replaced - or - the sensor was damaged or removed from the wheel. When the low air pressure alarm goes off it is THAT tire that is most often overlooked.
I4 does not have MAF.
should be a M18 x 1.4
3 sensors are on toyota altezza AT rs 200
This refers to the second oxygen sensor on Bank 1. Bank 1 is the same side of the engine that cylinder 1 is on, the very front cylinder on the drivers side. It could need to be replaced, or there could be a short to voltage on the O2 signal circuit, or it could also be that the connector has been corroded, and needs to just be cleaned. I believe this code is the same for all vehicles, not just Toyotas.
Trouble code P1725 means: Rear Wheel Sensor Circuit Malfunction
Front cover just above the crank pulley, behind the crank sensor, 1 wire light grey plug.
