Here's what the manual says for the ECT's temp (deg C) vs resistance. Pull of the top and use an ohmmeter to measure the resistance between adjacent terminals. Readings should be no more than +/-5% from those below. If so replace the sensor.

Temp(C)-Temp(F)---- Ohms
20 -------- 68 ----------- 2500
30 -------- 86 ----------- 1700
40 ---------104 ---------- 1170
50 ---------122 ----------- 830
60 ---------140 ----------- 600
70 ---------158 ----------- 435
80 ---------176 ----------- 325
90 ---------194 ----------- 245
100---------212 ----------- 185

Fixed TYPO error, tnx to Arthur Dalton
