depends on the code it is giving there is 2 and sometime 3 o2 sensors depending on model and year but there should be one in the manafold or just pass it and one after the catalitic converter but also some cars newer then 98 have one before the muffler...
what are the symptoms of bad tdc o2 sensor
You can visit a local auto repair store to have them detect whether your O2 sensor is bad or not. They can normally do this for free in a few minutes. A bad O2 sensor would trip the check engine light to come on. The code retrieved would lead you to the failed O2 sensor.
how do i know if the o2 sensor is bad. The check engine light would illuminate and the code(s) set would steer you to the faulty O2 sensor.
The check engine light would illuminate and set a code for the bad O2 sensor.
By "exhaust manifold sensor" do you mean the O2 or oxygen sensor? The only sensor I know of on a exaust manifold is the O2 sensor and if you follow the manifold you will see 2 sensors sticking out they will have (usually) green wires coming from them
When a O2 sensor goes bad the check engine light will illuminate. The code set in the ecm will lead you to which O2 sensor is bad.
Unfortunately there is no fixing an O2 sensor. If the "check engine" light is on due to an O2 sensor, it can only be remedied by replacing the bad sensor.
yes
A bad O2 sensor can affect gas mileage. It is an emissions sensor, so when it goes bad, it does not reflect emissions performance on the car, which could cost a lot in gasoline.
The bad one.
That is a heated O2 sensor.
When an O2 sensor is bad your car will not run efficiently. You will use more gas than you would normally use on a trip.
