2000 Chevrolet Metro Parts Questions & Experts Answers

• Q: How should the Oxygen Sensor 2 be serviced to ensure proper performance and avoid damage on 2000 Chevrolet Metro?

  A: Service the Oxygen Sensor 2 with proper sensor handling that includes no dropping of heated Oxygen Sensor (HO2S) units while maintaining all electrical connection points along with louvered ends free from contaminants; avoid using cleaning agents on the device. Replacement of the Oxygen Sensor stands as the proper course of action in case of wiring or connector or terminal damage. Attempts to repair any components of the external clean air reference by following the Oxygen Sensor signal and heater wires will create obstruction and result in performance degradation of the sensor. Contact cleaners should be used with caution near the sensor because applying them to connectors might damage wire harnesses and sensor pigtails while causing lead wire wrinkling which affects sensor performance. The removal of Oxygen Sensor ground wire should not be performed since it functions as the sole sensor ground while maintaining the integrity of vehicle harness peripheral connector seals to block water entry. The packard's crimp and splice seals terminal repair kit should be used for engine harness repairs while preventing soldering to avoid blocked air references. The ho2s removal may become challenging when temperatures exceed 120 fahrenheit so let the engine reach room temperature before performing removal work to preserve the Exhaust Manifold threads. Detach the electrical connector of ho2s 2 before removing it from the Exhaust Pipe. Pay attention to retain the protective anti-seize coating on the installed ho2s 2 sensor since reinstalling a pre-removed sensor requires the additional application of anti-seize compound on threads. The technician must install the ho2s 2 to the Exhaust Pipe followed by tightening to 40-50 n.m (29-36 lb ft) then attach the ho2s 2 electrical connector.
