The 1999 Chevrolet Cavalier came average with a 115-horsepower, 2.2-liter four-cylinder engine and had a 150-horsepower, 2.4-liter four-cylinder engine available in the Z24 models. Both engines utilized two emissions sensors in the exhaust course: a heated oxygen sensor and a catalyst overseer sensor. The heated O2 sensor measures the magnitude of pollutants forthcoming from the engine as exhaust leaves the engine. The Cavalier's machine then compares this reading to the reading from the catalyst monitor to impel whether the catalytic converter is operating fair. Replacing this sensor is a relatively active duty, however it requires a speciality effects.
Instructions
Plug the oxygen sensor's wiring harness into the Cavalier's wiring harness.
Press the locking Press-stud on the wiring harness and seperate the O2 sensor wiring harness from the Cavalier's wiring harness.
3. Remove the O2 sensor from the manifold, using a ratchet and oxygen sensor socket. If the sensor seems stuck in the manifold, apply heat to connection point between the sensor and the manifold, using a propane torch.
4. Coat the threads of the new oxygen sensor with an anti-seize chemical, if not pre-coated, and hand-tighten the sensor into the exhaust manifold. Tighten the oxygen sensor to 30 foot-pounds, using a torque wrench and socket.1. Establish the oxygen sensor on the side of the exhaust manifold, equitable above the flange connecting it to remainder of the exhaust process. Hint the O2 sensor wire out from the sensor until you come to where it connects to the Cavalier's wiring.2.
