Frequently Asked Questions

Find answers to common questions about torque specifications

Q1

What is the function of the oxygen sensor in the 2013-2021 Acura ILX?

The oxygen sensor, also known as the O2 sensor, monitors the oxygen levels in the exhaust gases. It provides real-time data to the Engine Control Unit (ECU) to optimize the air-fuel mixture for efficient combustion, reducing emissions and improving fuel economy. The sensor operates at a voltage range of 0.1V (lean mixture) to 0.9V (rich mixture).

Q2

How often should the emissions sensors be replaced in the Acura ILX?

The emissions sensors, including the oxygen sensors, typically have a lifespan of 60,000 to 90,000 miles. However, this can vary based on driving conditions and fuel quality. It is recommended to inspect the sensors during routine maintenance and replace them if diagnostic trouble codes (DTCs) such as P0135 or P0141 are detected.

Q3

What are the symptoms of a failing emissions sensor in the Acura ILX?

Common symptoms include illuminated Check Engine Light (CEL), poor fuel economy, rough idling, hesitation during acceleration, and increased emissions. Diagnostic tools can read specific DTCs to confirm sensor failure, such as P0130 (O2 Sensor Circuit Malfunction) or P0420 (Catalyst System Efficiency Below Threshold).

Q4

Can I replace the emissions sensors myself, or should I consult a professional?

While it is possible to replace emissions sensors yourself, it requires specialized tools and knowledge of the vehicle's exhaust system. Improper installation can lead to damage or incorrect readings. It is recommended to consult a certified Acura technician to ensure proper installation and avoid voiding the vehicle's warranty.

Q5

What is the difference between upstream and downstream oxygen sensors in the Acura ILX?

The upstream oxygen sensor (before the catalytic converter) monitors the air-fuel ratio for combustion optimization. The downstream oxygen sensor (after the catalytic converter) checks the efficiency of the catalytic converter. Both sensors are critical for emissions control and must function correctly to pass emissions tests.
