I believe I need a new CTS connector pigtail because when I back-probed the connector to read the ohms when I was testing the sensor, I did not get a reading, I got 0 ohms. However, when I unplugged the connector and tested it directly, I got the proper reading. I then proceeded to test for continuity from the connector back to the ECU and that was perfect, so I am guessing I need a new pigtail? Is it okay to cut the wire and solder in a new connector I buy at the parts store?

Yes.

adamj

Okay, because I thought some sensors like the o2 sensor you can't solder, is that true?

cruiser54

Yeah. That's the only one that has a shielded wire in it.

adamj

So what do you do in that situation with the o2 if you need a new connector?

cruiser54

Go out to the pump house and get a spare harness.....

Most of these guys don't have a pump house. I still have my old one its concrete block, my new well has everything in the basement of my new house. NO more frozen pipes!!!

What's a pumphouse?

cruiser54

The building where my well head is. Houses the pressure tank etc. Plus tons of Jeep parts.

How about the knock sensor? I see it has a shielded wire or something, how do I go about soldering on a new connector there?

cruiser54

The O2 sensor has the shielded wire doesn't it?

Knock sensor has a connector like a fuel injector.
