My O2 sensor seems to not be working. I backprobed it with my Fluke 115 which usually is fast enough to pick up the voltage swinging back and forth. I'm getting a steady 5v. The old O2 is an NTK which lasted about 2 years so I decided to go back to Bosch and give them another try.
The new Bosch O2 is labeled pn 12009 on the box, but is labeled as LSH 24 on the body of the sensor. Is this the right part? I don't think it is. Looks different too. Engine runs rich slowly to lean until it almost stalls and then the computer gives little more fuel and the cycle repeats.
I'm going to send it back to Amazon. Any one else run into this?
