And if you continue driving for several months, it may lead to engine damage or catalytic converter failure which can cost thousands of dollars to fix or replace. What happens if you keep driving with a bad O2 sensor?ĭriving your Chevy Cobalt with a bad O2 sensor can cause sluggish and rough acceleration, along with high fuel consumption and emissions. Connect the electrical plug of the new sensor.Screw in the new O2 sensor by hand and tighten it up with a wrench.Apply anti-seize lubricant to the threads of the new sensor.Make sure the engine is cold before replacing the sensor to prevent burn injury.

All you need is a wrench for this replacement job. You don’t necessarily have to visit a workshop to replace oxygen sensor in your Chevy Cobalt. You can also perform a continuity test on the connector of the sensor with a multimeter to check if the heater circuit is broken.

If you see any error code from P0130 to P0135 or from P0150 to P0155, it indicates a problem with the upstream oxygen sensor. You can diagnose the problem by connecting an OBD2 scanner to your vehicle. If there is any fault in the oxygen sensor, it usually illuminates the engine check light in the instrument cluster of Chevy Cobalt.

How to check for bad O2 sensor in Cobalt? This suffocates the engine and causes performance issues. because of bad O2 sensor), the exhaust gases cannot pass through easily. If these pores get clogged due to improper engine combustion (e.g. Catalytic converters contain honeycomb-like structures with tiny pores that are coated with platinum, rhodium, or palladium depending on the catalyst stage. Because O2 sensors are relatively cheap compared to the price of catalytic converters, which can easily cost you over a thousand dollars to replace.

If you suspect a problem with O2 sensor in your Cobalt, you should act immediately and get it checked by a professional mechanic. Bad O2 sensors lead to catalytic converter failureįaulty oxygen sensors are the leading cause of premature catalytic converter failures. If this sensor goes bad, it does not have any affect on the engine performance, but the check engine light may illuminate and you may see error codes related to catalyst efficiency. The main purpose of downstream O2 sensor is to ensure that the catalytic converter is functioning properly. The downstream O2 sensor in Cobalt is located further down the exhaust system, after the catalytic converter, and is responsible for measuring the level of pollutants passing through the catalytic converter. Downstream O2 sensors do not affect engine performance Any fault in this sensor can cause all sorts of performance issues in your Cobalt. The upstream O2 sensor helps in maintaining proper air to fuel ratio in the combustion chambers for maximum fuel efficiency and engine performance. But the most important one is the upstream O2 sensor, the one that is closest to the engine, usually in the exhaust manifold. There are multiple O2 sensors in Chevy Cobalt, how many depends on vehicle configuration and model year. Upstream and downstream O2 sensors Upstream O2 sensors are important for engine performance
