Operation: Penetrating oil is specially designed to penetrate very slight openings like those found between the threads of a nut and bolt. Advice: Spray the penetrating oil onto the threaded area of the old sensor liberally and let soak in for ten to fifteen minutes. Repeat this process two or three times before attempting to remove the old oxygen sensor. Recommendations: Penetrating oil
Operation: An oxygen sensor socket is a specially designed socket with a slot in the side to accommodate the sensor wiring. Advice: The location of the oxygen sensor and the amount of available working room will usually dictate which tool that you use to remove it. There are a couple of different designs for oxygen sensor sockets. Most incorporate a slot to accommodate the wiring harness. This slot however also weakens the socket. If the oxygen sensor is very tight, it can cause the socket to spread at the slot and slip, rendering the socket ineffective. In cases such as this a box end wrench is sometimes effective. As a last resort you can cut the wires off of the old sensor and use an air impact wrench with a solid deep-well socket. Recommendations: Oxygen sensor socket
Operation: Many oxygen sensors carry a different part number only because the wiring connector is different. The sensor is the same. A universal oxygen sensor can be purchased often for a lower price, without the wiring harness connector. Advice: Before deciding whether or not to use a universal sensor, first ensure that the connector on the old sensor is still serviceable. Unplug it and inspect it for any broken tangs or missing rubber seals. Most universal oxygen sensors come with crimp connectors for attaching the wiring of the old connector to the new sensor. This style connection is adequate when new, however over time condensation and other forms of moisture can cause corrosion. Since the signal that the oxygen sensor sends to the ECU is almost always less than one volt, it would not take very much corrosion to alter it's signal. It's a good idea to solder the connections and seal them with heat shrink.Use rosin core solder. Acid core solder will cause corrosion in electrical connections. Recommendations: Soldering gun Rosin core solder Heat Shrink tubing
