2011 Ford Escape 3.0 Code P1489

I have a 2011 Ford escape that has a code P1489. P1489 is is PCV Heater control circuit fault. When we removed the pcv valve to check the heater, there was no electrical connector in the pcv valve. The vehicle has 175000 miles on it and the pcv valve appears to be the original by looking at it. Has anyone run into this before and do I put a new one in that does have the heater in it? Check engine light is NOT on.

Is there a wiring harness connector? If so, replace it with the proper valve.

There is a connector and it is plugged into the pcv valve that has been in the vehicle forever. I am assuming that this code does not turn the CEL on so it has gone unnoticed forever. I will order the proper valve and give it a try. I can't believe that Ford sent this out this way.

I think I mis-understood your original post. I assumed that the valve did not have a connector to plug into, implying that the wrong valve had been installed.

Is the code a current code? Or, history? Does it come right back, if you clear it?

There are a few checks that you can do before replacing the valve.

Check 10 amp Fuse 27, in the engine compartment fuse box. It should have battery voltage, with the key on.

At the valve, disconnect the connector and check the voltage between pin 1 and pin 2, of the wiring harness connector. You should have close to battery voltage, with the key on.

On the valve connector, set your meter to check resistance. Service information says resistance should be between 10 - 35 Ω.

We did have voltage at the connector for the heater, we cannot ohm the heater itself is because the male plugs that are supposed to be in the valve are not there. I am just making sure that this is not just the way they were made and it is normal. Valve is close to 50$ and I don't want to replace it if it is not needed. I have attached a photo but unfortunately it is not very clear that the connector is empty.

Yes on the code, hard code and will not clear.

Believe the heated PCV circuit works along with the intake air temp sensor. When the IAT temp is below 48° F it grounds the PCV.
Did the pins pull out when you disconnected the harness?

I wish I could say that they did, but we checked it very close. I made my students check the inside of the connector as they were checking for voltage. There is no evidence of there ever being any terminals in the pcv valve at all. I think I will go ahead and purchase a new one, see if that keeps the code away and then cut the old one apart to see if there is anything in it.

To make sure the code will go away you temporarily could install a substitute load instead of the valve....
