Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What type of emissions sensors are used in the 2019-present Acura RDX?
What type of emissions sensors are used in the 2019-present Acura RDX?
The 2019-present Acura RDX is equipped with a combination of oxygen sensors (O2 sensors) and a NOx sensor. The O2 sensors include both upstream (pre-catalytic converter) and downstream (post-catalytic converter) sensors, which monitor oxygen levels in the exhaust to optimize fuel-air mixture. The NOx sensor measures nitrogen oxide levels to ensure compliance with emissions standards.
Q2 What is the operating temperature range for the emissions sensors in the Acura RDX?
What is the operating temperature range for the emissions sensors in the Acura RDX?
The oxygen sensors in the Acura RDX operate effectively within a temperature range of 300°C to 850°C (572°F to 1562°F). The NOx sensor operates optimally between 200°C and 500°C (392°F to 932°F). Exceeding these ranges may result in sensor failure or inaccurate readings.
Q3 How often should emissions sensors be inspected or replaced in the Acura RDX?
How often should emissions sensors be inspected or replaced in the Acura RDX?
Emissions sensors in the Acura RDX should be inspected during routine maintenance, typically every 30,000 to 50,000 miles. Replacement intervals vary based on driving conditions, but most sensors have a lifespan of 60,000 to 100,000 miles. Always refer to the vehicle's maintenance schedule for specific recommendations.
Q4 What are the symptoms of a failing emissions sensor in the Acura RDX?
What are the symptoms of a failing emissions sensor in the Acura RDX?
Common symptoms of a failing emissions sensor include illuminated check engine light, reduced fuel efficiency, rough idling, poor acceleration, and increased emissions. Diagnostic trouble codes (DTCs) such as P0135 (O2 sensor heater circuit malfunction) or P2201 (NOx sensor circuit range/performance) may also be triggered.
Q5 Can I replace the emissions sensors in the Acura RDX myself?
Can I replace the emissions sensors in the Acura RDX myself?
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 inaccurate readings. It is recommended to consult the official Acura service manual or seek professional assistance to ensure proper installation and calibration.
