Coolant thermostat temperature check (P0128)

Post by rainy187 »

Do we need to have Coolant thermostat temperature check enabled (P0128) unchecked for the flex fuel calibration?
if it is unchecked, how or where would the car get that information from?

Are you getting an error code?

Do you have it checked or unchecked?
