Coolant temp sensor issues

I keep getting a error code 0021 on link. Two days ago, I replaced the sensor and ran new wires to the ecu since the wiring looked suspicious. I connected the grn/yel to pin 20 and the grn/bl to sensor ground pin 24. All was well yesterday except the car ran a little warm. I did check my thermostat position and turned it so the pin faced the block last night. Temps seem a little better but this morning my cel comes back on error 0021. Drop my kids off at daycare and the car won't start. I pop the hood and wiggle stuff and then it fired but I think its that cts.

The connector looks okay I sprayed some cleaner in there. Did I wire it wrong? There's a sensor ground pin 17 as well, but I think they are all connected though. Should I just ground the stupid thing out - but what consequences come from that? The darn fan runs all the time when it goes off so I want to get it fixed plus the not starting sucks too.

Thanks!

Well I think it's fixed. I had ran the lines in tandom with the stock harness thinking it was just a bad wire. It must have been shorting on something so I clipped of the factory wires and all seems well.

Thanks for the space /ubbthreads/images/graemlins/hsugh.gif
