ECT testing
Hi again. Is there a way to test a new ECT sensor before fitting to the car and what should the resistence be? As ya all know its in a stupid place to get to and i have hands like shovels. So would be nice to know before fitting its ok. Cheers steve

Saucepan and thermometre will do it.
10 C 6 K OHMS
20 C 3.75 K OHMS or 3 volts(return)
30 C 2.42 K OHMS
40 C 1.6 K OHMS
50 C 1.08 K OHMS or 1 volt(return)
60 C 0.75 K OHMS
70 C 0.53 K OHMS
80 C 0.38 K OHMS or 0.3/0.5 volts(return)
90 C 0.27 K OHMS

Last night i made up 2 wires to test the connection on the ECT, Plugged 1 end on sensor and other into the plug, the car still choked and died when warm, so i thought deffo sensor. But then i checked resistence on the old sensor and it seems to work ok to the figures, I not have temp gauge on the test but running sensor under a cold then hot tap showed a varied res as per figures.
So what the hell now? Today i will check wires for breaks with multi meter, Has anyone had this prob before or is it just captain lucky me. Am i right in thinking its pins 11 and 29 on ECU to test res in ECT and to do voltage check. Thanks again for any help given. I just wanna drive her again before the snow comes over here.
Ps could it be anything wrong with the stg 3 collins chip?
