2001 Chevrolet Prizm Question: oxygen sensor
Answer #1patrick mannion from Greg Solow's Engine Room, July 22, 2009, 22:07Master
The 1.8Litre Prism engine has only two Oxygen sensors. What is called bank one sensor one is located at the rear of the engine. Follow the exhaust manifold where it starts to bend and go down parallel to the firewall, the sensor is on the driver's side of the exhaust down pipe. The second oxygen sensor (called bank one sensor two ) is located under the car.
The sensor looks like this.
