In the 2001 Chevy Tracker, there are a total of 3 O2 sensors that play a vital role in the vehicle's emission and ignition systems. Sensor 1 is installed in the exhaust manifold, sensor 2 is located before the catalytic converter, and sensor 3 is placed after the converter. These sensors monitor the levels of unburnt oxygen in the exhaust pipes and send this data to the vehicle's main computer. This information is used to adjust the engine's air/fuel ratio for optimal performance. A functioning O2 sensor helps maintain good fuel economy and engine firing. However, if the sensors become faulty, they can cause the vehicle to run too rich or too lean, leading to issues like rough idling, decreased gas mileage, and potential misfires.
