P0528 Code after new Thermostat/Coolant Change

Hey Guys,

A few weeks ago I had a new thermostat put in and had my coolant changed at ford. Later that same day, I had the fan come on for about 30 seconds sitting in traffic idling, then it shut off. It was loud so I immediately panic'd!

I was only at 190 degrees for both EOT/ECT. I had done a couple hard runs 15 minutes pror to that.

I have a Scan guage II and checked for codes and it showed me "No Codes Found".

However, today (week late) I swung into my local dealer to see if I had any soft codes. They hooked up thier scanner in the service lane and said I had soft code:

P0528 PCM Cooling Fan Speed Sensor No Signal.

I researched online and checked my sensor and the wires are not chaffed, cut, etc..and they look good. I even unplugged it "blew inside" and reconnected it! hehe

The fan has not come back on full force like that again, temps are good, truck is running top dog. The service guy said it may be that there was "air in the system" after the coolant/thermostat change.

What do you guys think? Was this just a one time glitch? No CEL, everything runs perfect Only did this one time. Fan is spinning when running.

I'm probably being a worry wart, but wanted to check with some of you. I assume if there was a real issue the fan would be coming full force alot, displaying a cell, or running real hot.

Maybe this is a "Ghost" code and nothing to worry about, lol

Thanks

the fan clutch is by no means failsafe. They go bad quite often with the symptoms you describe. It's probably not gone yet but on it's way out.

If it's not doing anything right now don't worry about it but keep it in the back of your mind. If you do a lot of heavy towing change it sooner rather than later. some of our trucks that run around unloaded may never hear the fan kick on though. I know I've never heard mine.
