I was under the impression that 'Turning the light off' was just that - it turns the CEL light Off on the dash, but does nothing for allowing O2 sensor readiness in order to pass emissions OBD2 plug in test?
How do you pass emissions test in Cali with catless DP?
I was told that here in PA, with catless DP, even if light was turned off - I would not pass the test as O2 sensors would not show ready
Which is why I went with catted FabSpeed DP - I have not had a problem passing emissions with this DP & I have nothing turning anything off - it passes with DP & O2 sensors installed |
Me too!
