O2 sensor, will wideband pass emissions
So i failed my inspection, due to a bad o2 sensor. Not a big deal as I need a wideband o2 anyways due to my catless dp. However, will a wideband 02 sensor pass Massachusetts inspection?
Thanks, brendan

Nope on the wideband. Which O2 was bad? You have 2 you know.

You can replace the rear O2 sensor with an LM-1 or LC-1, and program one of the analog outputs to act like a factory rear O2 sensor.
If you were to do this, you would also need to disable the CEL for "heater circuit open"... possibly some others as well. |
