I've been to the dealer 7 times in the past two months. Dealer replaced coolant temp sensor, thermostat twice, PCM and the wiring from the temp sensor to the PCM. Service tech drove car home, drive cycle put 100 miles on it. I need to bring it back Monday, same code. What else can this be?

The code is identifying that the engine is staying cold too long. PLEASE KEEP IN MIND, THIS IS AN EMISSIONS RELATED PROBLEM THAT IS COVERED 100% BY THE MANUFACTURER FOR 5 YEARS OR 50,000 MILES.

Is there a fan clutch on your vehicle?
