Software update for false coolant sensor fault code on Honda Civic

On certain models the Powertrain Control Module (PCM) misinterprets data from the coolant sensor and sets a false Check Engine light (MIL). A software update from Honda is required for this repair.

I replaced the sensors, had the mechanic verify all testing perameters between the thermostat,radiator and engine all were found to be normal. However, the engine light remained lit. You can put it out with the code testing instrument but it will come back on in a short period of time.
Put a piece of black tape over light--goes out and on every other week--replaced thermostat and now it could be one of two sensors--another way for Honda to drain $$$ from the consumer!!!
