Hey everyone,
I have a check engine light that is very finicky. It is on for a twenty minute drive, shut off the car, come back two hours later, and it's off again for two days then comes back. I had the code checked when it was on and the code was PO597. I have a bumper to bumper warranty, so I'm not worried about cost. But I was wondering if anyone knew what this issue is, and also what the repairs entail? How long would this take? I'm 22, and unfortunately i cannot drive a rental car yet (which is ridiculous IMO). I want to wait for the repairs to be done while I'm there...

Thanks,
Ben

Thermostat Heater Control Circuit/Open. Most likely the thremostat or cracked breather hose. In either case they should be able to repair it while you wait.

Sounds like it's time for a new thermostat.

Ben, check your coolant level as well. A cracked thermostat can leak coolant everywhere. Out of curiosity, are you driving an LS?

I will check the levels when its light and somewhat warmer, probably in the morning. And possibly? Sounds awful to say, but i have no idea. I dont have any audio package (stock at least), no rims, no spoiler, no body kit. So idk, does that sounds like an LS?

If there's no badge in the right corner of your trunk lid, it's a LS model.

LS models have been known to have leaks at the thermostat housing, which has been updated.

Thanks patsy! I appreciate it. I do have a 125K mile bumper to bumper, so I'm not worried about the cost. I will be setting up an appointment for next week and will let everyone know how it goes. And if I need anything patsy, nice to know I can contact you here.
