Nothing in the factory cortina manual either, seems sender resistance is uber secret or sumink, even the intermotor catalog shows everthing appart from temp sender ranges, shows oil pressure switch ranges, rad fan on and off ranges but buggerall for temp senders. The coolant temperature sensor (CTS) is often located near the thermostat of a vehicle’s engine so that it can operate at its optimum level. On the temp sensor it is a 4 pin contact. If your temp sender is a 'gauge' type (and not an "on-off" switch style) you should see a linear change in resistance values as the temperature of the engine rises - the ohms will get lower, and hold steady at something like 33-45 ohms. 00 out of 5 based on 1 customer rating (1 customer review) $ 38. No its not the sensors. Can also be used on 55's when replacing the original mechanical temperature gauge with the 1956 unit, Danchuk # 15955. 100 F = 1050 ohms (rising temperature) 150 F = around 330 ohms (rising temperature) 180 F = 174 ohms (rising temperature) (secondary calibration point) 210 F = 100 ohms (rising temperature) (primary calibration point) 250 F = 54 ohms (rising temperature) EST-250/300, ES2T-250/300 Senders:. A good temp gauge will measure about 60 ohms between its terminals. Today's coolant temp senders have two wires, one wire is feed a small amount of voltage from the computer while the second wiring is read by the computer and the engine temperature determined. Find out what resistance is delivered by 90C, then what voltage that allows through to the temperature gauge. Pt-100, single or dual element; Offers Callendar-Van Dusen constants for transmitter-sensor matching to provide the highest level of accuracy-321 to 1112°F (-196 to 600°C). The subsequent parameters provide precise sender resistance values for three specific gauge readings (Low, Medium, and High), hence, can be used to estimate sender resistance when actual physical parameters are known (e. Fits 351C and 351W engines. You Save $6. Resistance is basically 0 at the "cold" setting, and after soaking in some hot water, at roughly 170 degrees, was around 37 ohms. To Remove a sensor or switch wire from the sensor harness connector (J6), Insert the end of a paper clip into the slot corresponding with the wire to be removed. I pull the sender out, connect an ohmmeter across the sensor connection and the mounting plate, then read the resistance with arm hanging all the way down, then read it with the arm all the way up. So when cold it should be reading around 240 ohms, at very hot it should be 33 ohms. For years the only available temperature sending units were GM/DELCO, and for years they were not calibrated correctly which provided an incorrect resistance for the gauge. Low temperature will be indicated on the gauge. I would check the coolant temperature resistance at that temperature, since it has greater relevance. Sensors for Porsche 356 (1956-1965): Fuel Level Sending, Oil Level Sensors, Oil Temperature Senders, Tire Pressure Monitoring Systems (TPMS). Mechanics have been known to connect the O/D sender wire, to the wrong sender by mistake (there are three separate senders in the same place). Temperature sensor(?) behaving erratically. NTC thermistor The NTC type is used when a change in resistance over a wide temperature range is required. 40 ohms at the sender equates to the gauge resistance reading 40 ohms and stopping at the 180 mark. you can find the values listed in a Factory Service Manaual (FSM). I believe there is > another for the A/C. As an example the look at the datasheet for the AVRs that have a temp sensor. These are all 3/8-18 NPT. 3 Check the thread size of the port being used. The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank.
