The sensors are installed as a safety feature. If your sensor is permanently on, then the sensor it self will have to be replaced with a new one.
Oxygen sensors do no work well when they are cold so manufactures have installed a heater in the sensor to get it up to speed quickly.
The CA20E Engine has one oxygen sensor installed in the exhaust manifold.
two oxygen sensors for air / fuel ratio (and another two oxygen sensors that are called catalyst monitors installed downstream )
depends on the sensor .your question has to have more detail to it .Due to there is all kinds of sensors such as, temp sensor,knock sensor,o2 sensor,iac sensor,map sensor,idle air control sensor,mass air flow sensor,shift control sensors,transmission sensors,coolant sensors,hell there is even brake sensors and rear end sensors,some even have body sensors.
Errors PO405 to PO409 is because you have change your up-pipe to the turbo and might of not installed the EGT sensors or you have installed the EGT sensor and your up-pipe is very big.
Most oxygen sensors are heated oxygen sensors.
The #1 oxygen sensors are installed into the exhaust manifold. If a vehicle has #2 oxygen sensors, they are after the catalytic converter. Bank 1 is between the engine and the firewall. It is highly recommended that you replace both oxygen sensors at the same time, since the failure of one sensor is a good indicator that the other is about to fail.
The equipment and materials required to make your own motion sensor far exceeds the cost of purchasing one off the shelf.
an o2 sensor is the same as an oxygen sensor. vehicles can have up to 4
calibration of sensors to optimize sensor accuracy
A device that allows position measurement is a position sensor. There are absolute position sensors and displacement sensors that are relative ones.
