Mitsubishi Mitsubishi Endeavor 2004-2011 Emissions & Sensors Specifications

The emissions sensors for the 2004-2011 Mitsubishi Endeavor include oxygen sensors and catalytic converters designed to meet EPA standards. These sensors are compatible with the 3.8L V6 engine and are typically located before and after the catalytic converter. They operate within a voltage range of 0.1 to 0.9 volts and are compatible with OBD-II systems for accurate emissions monitoring.

Regular maintenance of emissions sensors includes inspecting for damage or contamination every 30,000 miles. Cleaning the sensors with a specialized cleaner can prevent build-up. Replace sensors every 60,000 to 90,000 miles or as indicated by diagnostic trouble codes (DTCs). Ensure proper electrical connections and check for corrosion periodically to maintain optimal performance.

To install or replace emissions sensors, first, locate the sensor near the exhaust manifold or catalytic converter. Disconnect the electrical connector and use a sensor socket to remove the old sensor. Apply anti-seize compound to the threads of the new sensor and install it, tightening to the manufacturer's torque specification. Reconnect the electrical connector and clear any DTCs using an OBD-II scanner.

Common issues include faulty readings or DTCs like P0130 or P0420. Start by inspecting the sensor for physical damage or contamination. Check the electrical connections for corrosion or loose wires. Use an OBD-II scanner to read live data and verify sensor operation. If readings are inconsistent, replace the sensor and retest to ensure proper functionality.

Optimize performance by ensuring the engine is running efficiently, as misfires or rich/lean conditions can affect sensor readings. Use high-quality fuel and perform regular tune-ups. Keep the exhaust system in good condition to prevent leaks. Regularly clean sensors and replace them as recommended to maintain accurate emissions monitoring and compliance.
