Get a scan to retrieve the trouble code for the MIL indicating. Most parts stores provides free scanning services.

You could have a loose wire connection at the ECT/gauge sending unit.

As the other reply states; get the codes retrieved and post what they are- these items are all controlled by the PCM, and the a/c and ECT plugs are next to each other in the PCM connector. This could simply be 2 wires shorted together causing your issues. If I can be of further help- Please let me know. Doc
