How does the O2 sensor in AutoZone work?
AutoZone’s aftermarket oxygen sensors can keep your engine running efficiently. The engine computer is responsible for calculating how much fuel the engine needs based on the amount of oxygen in the system, and it relies on a good O2 sensor to function properly.
Why is the oxygen sensor on my car not working?
The sensor is mounted in the exhaust manifold to monitor the amount of oxygen in the exhaust. Faulty oxygen sensors cannot send the correct air-fuel ratio data to the engine control module, leading to inaccurate guesses about the amount of fuel your engine needs.
What does the DTC code p0421 stand for?
What Does the P0421 Code Mean? Diagnostic trouble code (DTC) P0421 stands for “Warm Up Catalyst Efficiency Below Threshold (Bank 1).” It means that the oxygen sensor downstream of your vehicle’s catalytic converter on bank 1 is detecting that the converter is not working as efficiently as it should.
