💡Oxygen sensors measure oxygen in the exhaust, indicating lean or rich conditions.
🔧Air fuel ratio sensors provide more precise voltage readings for micro adjustments.
🚗Bank 1 sensor 1 is after the exhaust exits the engine, while bank 1 sensor 2 is after the catalytic converter.
💡Understanding the differences between sensors is crucial for engine operation and diagnostics.
🔧Oxygen sensors and air fuel ratio sensors play vital roles in maintaining the proper air-fuel mixture.
What is the role of an oxygen sensor in engine controls?
—Oxygen sensors measure the amount of oxygen in the exhaust and provide feedback to the engine computer to maintain the proper air-fuel ratio.
What is the difference between an oxygen sensor and an air fuel ratio sensor?
—While both sensors measure oxygen levels in the exhaust, air fuel ratio sensors provide more precise voltage readings for finer adjustments by the engine computer.
Where is bank 1 sensor 1 located in a Toyota engine?
—Bank 1 sensor 1 is located after the exhaust exits the engine, providing feedback on the air-fuel mixture before the catalytic converter.
What is the purpose of bank 1 sensor 2 in a Toyota engine?
—Bank 1 sensor 2 is located after the catalytic converter and provides feedback on the catalytic converter's performance.
Why is it important to understand these sensors in Toyota engine controls?
—Understanding these sensors is crucial for proper engine operation and diagnostics, as they play vital roles in maintaining the correct air-fuel mixture and emissions control.
