Hi, I’ve done lots of searches but can’t find much. The alarm comes on every now and then on my 5.7 motor. It’s a thunderbolt 5 ignition. I’m pretty sure it’s to do with the temp sensor. I tested that to ground when I removed the wire, the alarm sounded, when I took the wire off ground the alarm wouldn’t stop. Sometimes it stops sometimes it doesn’t. Would the icm be the problem? I have disconnected that and cleaned etc but still the same.
cheers
