Dodge Avenger 1995-2000 Emissions & Sensors Specifications

The emissions sensors for the 1995-2000 Dodge Avenger are designed to be compatible with all trim levels and engine configurations within this model range. These sensors are specifically calibrated for the 2.0L and 2.5L engines, ensuring accurate emissions monitoring. Always verify the part number with your vehicle's VIN to confirm compatibility, as minor variations may exist between model years.

Emissions sensors require minimal maintenance but should be inspected during routine service intervals. Check for corrosion, damage, or contamination every 30,000 miles. Ensure the sensor wiring is intact and free of wear. Cleaning the sensor with a specialized cleaner can help maintain accuracy. Replace the sensor if it fails diagnostic tests or shows signs of malfunction.

To replace the emissions sensor, first, locate the sensor near the exhaust manifold or catalytic converter. Disconnect the battery, then unplug the sensor's electrical connector. Use an oxygen 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 battery.

If the emissions sensor malfunctions, first check for diagnostic trouble codes (DTCs) using an OBD-II scanner. Inspect the sensor for physical damage or contamination. Test the sensor's voltage and resistance with a multimeter to confirm failure. Replace the sensor if necessary. Ensure the exhaust system is free of leaks, as these can cause false readings.

To optimize emissions sensor performance, ensure the engine is properly tuned and running efficiently. Use high-quality fuel and replace the air filter regularly. Avoid short trips, as the sensor needs time to reach operating temperature. Periodically clean the sensor with a specialized cleaner to remove contaminants that may affect accuracy.
