Re: check engine light on my 03, I got the code 0128

03? you mean 04?

I got that same thing on my '04 before I traded it in. Dealer said I needed a new thermostat and quoted me $330 to replace it. I had 0126 and 0128 codes. Do you notice that it takes a long time for your car to warm up? Thats a pretty tell tale sign that its the thermostat. Its perfectly safe to drive.. but you may want to get it fixed.

Hmm.. mine always sits in the middle between hot/cold. Always did on my 04, and does on my new 09. I also have no idea why that particular dealer quoted me so much. The thermostat itself is only about $40. Theres a how-to on here for replacing it... its on the backside of the engine (firewall side) if I remember correctly.

Yeah, it might not be easy to change. Just take it to your dealer and tell them to check it out. They'll probably pull the code themselves just to make sure. I dont know how many miles you have, but I hope you're still under warranty ;).

It'll come back.. just not right away. Generally they wont do the service unless they actually read the code. You're lucky if they only charge you $50 to read the code.. the dealers around me charge $100.

Hmm, maybe your dealer will actually believe you and not have to pull the code. One of the dealers I go to said they had to pull it themselves.. but I think thats just their way of grabbing more money out of their customers pockets.
