Infiniti EX35 2008-2013 Emissions & Sensors Specifications

The emissions sensors for the 2008-2013 Infiniti EX35 are specifically designed for this model and may not be compatible with other vehicles. These sensors are calibrated to meet the emissions standards and engine specifications of the EX35. Always verify compatibility with your vehicle's VIN before purchasing or installing sensors. Using non-compatible sensors can lead to incorrect readings, check engine lights, or emissions test failures.

Emissions sensors in the 2008-2013 Infiniti EX35 require periodic inspection to ensure proper function. Check for any signs of damage, corrosion, or contamination during routine service intervals, typically every 30,000 miles. Clean the sensor tips if necessary and replace them if they fail or show reduced efficiency. Regular engine maintenance, such as using quality fuel and timely oil changes, also helps prolong sensor life.

To replace the emissions sensors, first, locate the sensors on the exhaust system. Disconnect the electrical connector and use a sensor socket to remove the old sensor. Install the new sensor by threading it in by hand to avoid cross-threading, then tighten it to the specified torque. Reconnect the electrical connector and clear any error codes using an OBD-II scanner. Always refer to the vehicle's service manual for specific instructions.

If the check engine light is triggered, use an OBD-II scanner to retrieve the error code. Common codes related to emissions sensors include P0420 (catalyst efficiency) or P0135 (oxygen sensor heater circuit). Inspect the sensor for damage, contamination, or loose connections. Replace the sensor if necessary. If the issue persists, check the exhaust system and catalytic converter for leaks or damage.

To optimize emissions sensor performance, ensure your Infiniti EX35 is regularly serviced with high-quality fuel and air filters. Avoid short trips that prevent the engine from reaching optimal operating temperature. Use a fuel system cleaner periodically to reduce carbon buildup. Keep the exhaust system in good condition to prevent leaks or blockages that could affect sensor readings.
