GM Bob, i've got...

GM Bob, i've got an interesting one regarding a p0128 on a 2006 Pontiac G6. I've recently replaced the thermo & the ECT. Each time i replaced these parts the MIL P0128 came on after she time So my question is could this really be a defective thermo or could something else be causing this

Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

I've believe the coolant is strong but I've not tested it. No more than one year old

Hello, my name is***** what has been done it sounds like your computer needs to be reflashed. The most common cause is the thermostat, I'd consider replacing thermostat with OEM AC Delco Brand if you haven't already and after that have computer reflashed. Here is a copy of the bulletin related to reflash. Let me know if you have more questions, thanks.
