How O2 Sensors Work & Why Replace Them
Why O2 Sensors Fail & Need Replacement
O2 sensors work in harsh conditions - exposed to extreme heat and toxic exhaust gases. Over time, they become contaminated with oil, fuel, and other deposits, causing them to send incorrect signals to your engine's computer.
Common signs of a bad O2 sensor: Check engine light, poor fuel economy, rough idle, and failed emissions tests.
