I was reading some of the other posts about this code and have some questions. I periodically get this code and clear it. I t may stay gone for a while and it may not. I think I am going to change the TSTAT out and start at this point. I would like to Know which TSTAT to use. Do I need to use the 180 or 195 I need help? I have a 2000 4x4 with a 4.6L in it. I have not noticed the temp guage not working maybe it has been working a little slow. Will this repair my problem.Any help will be appreciated. Thanks in advance.
So would this also apply to me? I went yesterday to get a Smog Check on my 2000 Lincoln Town Car which has a Ford 4.6L and failed with code PO125. Low ECT for Closed Loop Fuel Ctrl. I just had a new intake manifold and thermostat put in last year!
