Almost a year ago, I had my check engine light come on and I got code 0128. I looked that up and it said the engine temperature was operating below thresh hold. Tonight I got the same code again. I didn't change the thermostat last time, I pulled fuse 11 and the light went off never to return until today.
In both situations the outside temperature was under 30 degrees and there was snow. I didn't let the engine warm up and when I drove off and I didn't get up to speed quickly. Should I go ahead and replace the thermostat or should I just keep driving and not worry about it? I'm thinking it could be more the circumstances other than a defective part.
Thanks for your time
may need to replace i need to do the same. my weather is nice in socal but my thermostat reads cold.
Should you still see this Code pop up even after replacing the Stat, then I would start looking at the Coolant Temp Sensor(s) Connections, and the Sensor(s) themselves...
i agree with MOL, happened to me a couple of times
De Molded-KMC Jacks and Fives-Tinted Tails-Black Housing Headlights-Two Tone Bumper-Toyo Proxes 4-Drilled/Slotted Rotors-CSRT8 Diffuser-AFE CAI-Diablo-Removed Resonators
Econo Heads-Sidewinder Cam-JBA Headers
mines on daily. light went out after fuse 11 then 10 mins driving popped up again!
Thanks for the replies.
I'm still running the stock thermostat. From now on I'll let the engine warm up before I drove off. If it only comes on once or twice a year I would think the thermostat is still good.
Thanks for your time and help everyone.
i have the same problem here in mn, drive around in less than drive till you have at least 180 degrees indicated through EVIC and have the heater off or very low for that time. Mine finally cleared its own code after about a month of the CEL being on at me, and i havent seen a day above 25 out in that entire month. From what i learned the cold air intake dosent help: and being in manual mode overrides the cylinder cutout so its always a V-8 helps get to temp faster. works for me so far
I would say replace it, better be safe then sorry. Make sure you replace it right though! I really screwed up my old camaro replacing mine...
any news? i have found really just leaving it in 4th on the freeway for till i get temp has made the difference needed to keep the light off, and cyceling the heat. Watching it climb on evic is a good passer time on the back roads before you get into real driving too
I haven't drove my Magnum in over a week. I did drive it right after the code popped up and I reset the computer. The code didn't reappear. I'll wait it out and see if it comes back on.
