I need to check my ecu temp sensor, per poor 'cold starts' and poor 'cold' running and was wondering if anyone knows how to do this...I am handy with wires and a voltmeter

well resistance testing is not the best option in my opinion. I just recently added a good 45 min. to a job due to resistance tests gone bad.

I would recomend checking voltage. back probe on the signal side.(key on) stone cold motor should have 4.6V aprox. start motor and watch the voltage drop. down to 1v or less at operating temp.
