hello! i’m back lol
I replaced that bad wire and still no luck. i’m not 100% sure it was even the right wire and i’m getting extremely discouraged because I don’t understand the diagrams in the book I have.
the wire I fixed was a group of 5 small orange wires leading to one so I took out the chunk that was cut multiple times and replaced it with a fresh one.
I guess my question is what do I do next if that didn’t resolve the issue? should i trace back from where the sensor is at and check those wires?
It appears to be in good shape so it may be making proper contact with the pin on the ECU.
Being as you've got it out, connect an ohmmeter to the metal clip and with a big long wire connected to the ohm meter, probe the other probe of the ohmmeter to the orange wire of your temp sensor wire or its connector to check for continuity.
That orange wire is probably broken or disconnected somewhere along its length.
The signal isn't making it from the sensor to the ECU.
Just browsed the schematic; that orange wire is the ground return for all sensors, that we agree on. If that wire was not making to the ECU plug then a whole load of other sensors wouldn't work and the car would -maybe- not even run at all.
What the OP needs to do is verify that the Violet/Yellow wire is making it to the ECU [pin 38]. Easiest way is to measure [with the ohmmeter setting] between pins 38 and 91 of the ECM connector. It should read SOME resistance, -the sensor's resistance. If open circuit THEN follow wires.
Above should be done with all connectors plugged in, battery disconnected.
