coolant temp sensor

[september]

hey what's up, I replaced my cts but I'm still getting code 13. I checked the harness for the ecu, the wire is def plugged in. I replaced it with a brand new sensor from autozone so it should be good. I checked the harness that connects to the sensor while the car was running and it was picking up signal on the multimeter. does this sound familiar to anyone?

reset ur ecm

unplugged the negative and positive leads to the battery today when I woke up. came home from work about 6-7 hours later and hooked the battery back up. Still getting code 13 my car is an s13, the previous owner replaced the radiator with an s14 radiator, and he def did some custom wiring. would this cause code 13 even though the sensor is fine? I'm at a loss here, thanks for the help.

strip the harness back. remove all the split loom and trace the harness all the way to the ecu. look for damaged/frayed wires, make sure its wired right

Check the CTS harness for voltage.. reset the ECU manually using the dial on it

yeah that was it, didn't realize you could reset the ecu that way still have code 34 though, but that's a different story for a different day.
