While under the Jeep today doing PM, I noticed the coolant temp sensor plug to the harness had hit the exhaust manifold . not sure when or how. Both the female and male connectors are toast. The new sender will have the female. Where do you get the male end, and how do you splice the harness wires to it?

Without the sender, what is the system defaulting to?

 

See below for parts needed.

 

Google is your friend, parts will be here Friday: Standard Motor Products TX-28 sensor, Dephi 2 pin weather-pack connector.

 

Let's see a photo. The CTS has a pigtail on it. Knock sensor doesn't.

 

I know it's not the knock sensor. It's up on the block, not by the pan. It looked like a weather-pack connector.As long as the two wires are connected, would it matter?

 

Just clarifying.

No worries on polarity or anything.

 

Great. I always worry when the master speaks Happy Thanksgiving Cruiser!

 

Happy Thanksgiving to you and yours.

What do you think the eCU is seeing with a cTS disconnected?

 

-40 due to an open circuit? Very rich?
