[QUOTE="Mark Kovalsky, post: 1540878, member: 1654"] That is not how the sensor is supposed to work. What is happening is that when you see the OSS reading the PCM has calculated what the OSS should read and substituted that in place of the actual reading. You have either a bad OSS or a damaged wire between the PCM and the OSS. My money is on the wire, not the sensor. [/QUOTE]
