My specs say at 68 degrees the resistance reading of my ECT should be 2100-2300, can anyone tell me if this is right/wrong. or just what specs does your book give. because at 70 degrees, my sensor reads 10320, and its brand new. and ive tested 3 others also. WTF is going on here? Please PLease someone help me im gonna freak out, or just sell the car

My specs say 2.1k to 2.7k at 68 degrees, so you have the right specs. What is your meter set to? Some meters have different decimal placement settings, and also range settings, so be sure its on the 1k ohm scale. As temp increases, the resistance decreases, so if your meter is not set correctly, it would be reading 1032 ohms or 1.03k, which would be about right for 70 degrees. At 178 degrees, my specs call for 260-360 ohms.

how would the meter read 103.2? if the specs call for 2.1 to 2.7? if it reads 103.2 thats 10320 ohms, and if im thinking correctly 2.1 to 2.7 should be 2100 to 2700 ohms Correct??

Yes, spec is 2,100 to 2,700 ohms(2.1K to 2.7K, K=1,000) Some autoranging multimeters will show a smaller decimal number, like 2.7 and have a "k" on the display to denote a reading in the thousandths. What type of meter are you using? An autorange meter will only have one position selection to measure resistance, while non auto ones will have several positions to measure, for example- 20, 200, 2000. You would select the 2000 range, since that is closest to what you are measuring. On some meters if its not set right, it may show a number with the wrong decimal place. Thats why i mentioned if your reading was an accurate decimal place, instead of 103 ohms, it could be 1,032 ohms. Easiest way to check is to get a regular resistor of known value, and measure it, to see how the meter reads it. Also, dying meter batteries will cause inaccurate readings as well.

Ok i get it your had me confused. Im using a regular multimeter. I dont understand why everytime i got to the parts store i get one with 10320 resistance. I even went to the deal, and yet again the same thing. Any ideas?

Im using a non auto meter by the way. ok i tested a sensor. at 68 degrees, i got 1414ohm and at 100 i got 932 ohms. The 68 degrees is off, but the 100 degree is fine.... What now?

Ok i got it i wasntmaking a good connection on the probes and the sensor. Ive got one and it works thank god],my fuel milage is back. Thanks for the help

Thanks YOU for replying when you discovered the problem. This is a tremendous help for those that use the search function (plus we're all curious too. ). I wish this was done with more frequency.
Nice job,
