- Buick Ownership
I have 2006 BUICK RENDEZVOUS 3.5 V6, when I driver the vehicle today the engine light come on. So I went to auto zone check the engine light it come out P0128, I have notice when I driver the car the temperature gauge does seem right, it looks lower. I watch couple video online and replace the thermostat, but the check engine light still on and temperature gauge was below the 1/2 . What’s normal temperature gauge should be? Did I do anything wrong or do I have to replace the coolant sensor too?
