    I have a persistent Check engine code of P0125 that keeps coming back even though I have recently changed both of the CATs, all four O2 sensors, the air filter, the serpentine belt, the Electronic Temperature Sensor, and the thermostat. I need to get it to pass inspection for State of Massachusetts next month and I'm told they will not pass it with a check engine light on.

    Anyone else have any ideas of what to check or do next??

    I don't dispatch anymore. But I used to dispatch for Atlas Bulk Carriers (shut down by legal action in the '90s) after that for Harrison-Nichols (Irwindale, Ca) and last for Beneto Bulk Transport (Long Beach, Ca)
    But I drive now.

    Is the coolant level correct?

    One of my last cars was impossible to pass smog, I took it to a performance build shop and had to take a picture of my registration and fwd it, $300 later it was registered.
