Updated. October, 2003. INTRODUCTION. ALLISON 1000/2000 SERIES. Beginning at the start of production for the 2000 model year, General Motors introduced two new Allison automatic transmissions referred to as the 1000 Series and the 2000 Series, for light duty (8600-19850 GVW) and medium duty (19850-3000 GVW) commercial trucks..

Oct 15, 2008. #2. This is some very good info, especially the coolant sensor is a very interesting read with the step in the voltage. I think this is worth keeping as it shows the voltages one would expect to see when checking the sensor if you fuel consumption is up and you suspect the temp sensor. Youv'e had a barry with the cas link, i've.

There are actually two sensors which feed information through their resistance to the ECU. At 60-70F they should both read roughly between 950 and 1000 Ohms. If it's cold out and especially the coolant temp sensor fails with open circuit, the most common, you will not be able to start he vehicle.

Footnote: If you ever have to test the IAT, it operates the same as the two lead coolant sensor. The same temp vs. resistance table above is applicable to the IAT, as well as the +5vdc lead and ground wire at the harness connector. edited 1/03/2005 Knock Sensor. The knock sensor system is used for the detection of detonation. I popped out the temp sensor last night, took the easy way out and just threw a few pails under the truck and let it drain out. Probably less then a gallon of coolant came out (didn't actually measure but fairly certain) so that's all good. Hopefully pop the new one in this weekend when the wife brings it home and I'll have a working temp again!.

"ALL" GM temp sensors run on variable resistance (thermistor) to ground, no voltages whatsoever. The temp gauge sensor should be on the drivers side cylinder head between exhaust ports 1 and 3 with one single dark green wire attached. That sensor sends a "resistance signal" (not voltage) back to the gauge or idiot light depending what is used.

So the fan circuits work but neither the temp sensor on the car or my aftermarket one go down low enough in resistance. The aftermarket one is PN: FOR4337456 which is the.

Another thing that can be done, is to take a resistance reading of the sensor. I should be able to match that to a chart and determine if it is showing excessively low temperatures. That is what would have to be occurring for it to be the coolant temp sensor. It would have to measure below zero to cause a flooding condition.

The sensor does not control the fans, the PCM does based on coolant temp (from ECT sensor), A/C head pressure, vehicle speed and when certain trouble codes are set. Stock fan turn-on temperatures are pretty high, 225F primary and 232F secondary. Also, the temp sender for the gauge is in the cylinder head and does not correspond well to the ECT.

One is the ECT or engine coolant temperature "sensor" which feeds info to the computer and the other is a coolant temperature "sendor" which supports your instrument temp gauge. So the answer to your original question would be Yes.
Guess you were wrong or you gave me the resistance to one for a dummy light. Tested an original sending unit. 24 ohms in boiling water. 375 ohms under tap water (approx 60 degrees). Wow! That's really strange. I thought all Ford gauges (exception of the ammeter) were roughly 23 - 78 ohms.
