Cold lowest reading for temp gauge is 130 after starting and driving needle stays on 130. After motor is warmed up if shut motor off then turn key to power temp gauge reads correctly and will keep reading correctly. If start motor needle will start out reading correctly but will start to gradually drop until it is sitting at 130 since that lowest it can go. I have checked power from pcm and it is reading steady 5.181. Replaced the ect and even tested to make sure it was working correctly. I jumped the wires that go to the ect and gauge jumps to around 190 but will gradually drop to 130 with it running. I am trying to find a diagram from the temp gauge back but no luck so far why hoping you can help me figure out the problem or narrow it down.
have the same problem?
