bad O2 sensor
1st o2 senor is between exhaust. 2nd o2 sensor is under shifter
A bad O2 sensor could cause the engine to overcompensate for what it believes to be a problem. It will tell the engine to let in more or less O2 and could damage the engine in the long run. The sensor is not too expensive to replace and could save you LOTS of money in the future.
A defective O2 sensor will not prevent the engine from starting. The engine will start and run albeit not as it should.
The check engine light would illuminate and set a code for the bad O2 sensor.
Yes.
A bad o2 sensor could confuse the cars computer. This can make the computer to send wrong signals to the engine, resulting in the engine not running properly.
The "check engine" light would illuminate.
it is bad for the catalytic converter and O2 sensor. It is also bad for the environment. Your engine also has less power due to the worn rings and loss of compression.
Not likely. A bad O2 sensor would illuminate the check engine light and the engine performance would suffer.
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.
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.
