Coolant Temp Sensor Resistance Gm
Coolant Temp Sensor Resistance Gm. The 1st graph shows the comparison of the newer computer controlled (ohms)) signal (top line), and the older (ohms) value on the lower line which would apply to the 60's and early 70's cars. Resistance should be 1425 at 100*f (cold) and should decrease as it warms up.
Coolant temp sensor resistance chart written by kupis on august 27, 2020 in chart nissan maxima service and repair manual coolant temperature sensor resistance temperature gauge repair blue vs black temp sensors ohms cts temp table for a. Gm style coolant temperature sensor. These measurements produce essential data for the engine system of your vehicle.
The Ect (Engine Coolant Temperature) Sensor Is A Thermistor Which Changes Resistance Based On Temperature Of The Coolant In Contact With It.
In cold engine and an ambient temperature of 20 ºc the sensor resistance is between 2000ω and 3000ω. One wire is a 5 volt supply from the pcm (powertrain control module) to the ect. The thermistor used has a low resistance when hot, rising as the coolant cools.
Coolant Temperature Sensors Are Also Known As Engine Coolant Temperature Sensors Or Ect Sensors.
Sensor part number gm 25037332 pigtail standard s963. 18.90 mm (3/4) dissipation constant: Videos you watch may be added to the tv's watch history and influence tv.
A Ford Coolant Sensor, By Comparison, May Read 95,000 Ohms At 32 Degrees And Drop To.
If you were to test the coolant temperature sensor alone, you may think that it failed because its resistance value has remained at about 1500 or 2100 ohms, for example, when in fact the sensor is reporting the coolant actual temperature and it's working properly. There are no comments to display. Locate the coolant temperature sensor on the driver's side of the engine block, just behind the power steering pump.
I Think I'll Try It And I'll Measure Again With The Laser While Running.
You will search for the sensor within the engine block itself, using a drop light if you need help to see it better. Gm ect and iat temperature sensor resistance chart. Cts is used to control fuel mixture, timing, idle speed, tcc and egr operation, among others.
The Principle Working Of This Sensor Involves The Use Of An Electrical Resistance That Measures The Temperature Of The Coolant.
The engine coolant temperature (ect) sensors function is, to monitor the temperature, of the engine’s coolant. Here's a chart that gives the resistance values at a wide range of temperatures. Post by rappse » sun aug 02, 2009 9:36 pm.
