Hey everyone, I'd like to see if there is any new information regarding this issue. The latest credible posts I have seen are years old and I'm not sure if there have been any new solutions since then as far as the CAT diagnostic on 04+ vehicles.
Latest information I have found:
O2 simulators do not work.
One "solution" is do disable CEL but leave the code active, emissions test fails but no annoying light.
Another "solution" is to disable the code, but CAT diagnostic runs continuously, harming fuel economy.
Another "solution" is to disable the code, and run car in open loop to circumvent the fuel consumption of the diagnostic test.
Are there any other options now for handling this?
