How many O2 sensors does a 2005 Chevy Suburban have?

Answer:
The 2005 Chevy Suburban has four oxygen (O2) sensors. There are two O2 sensors located on the exhaust manifold before the catalytic converters, and two O2 sensors located after the catalytic converters.
Please note that the O2 sensors in your vehicle are designed to measure the exhaust gases to ensure they are within the correct range for operation. If one of the sensors has a problem, you may notice that your engine is running rough and you may also see a check engine light on your dashboard. In such cases, you can use an OBD II scan tool to confirm the fault detected by the sensor.
