There are 2 sensors 1 is temp sensor for dash gauge and 1 is engine coolant sensor for computer. Does the upper radiator hose get hot and pressurized. The engine coolant sensor has two wires one has a reference voltage 5 volts and the other is signal return to computer with key on is will have a minimal voltage .25 volts this tells you that the wire is not broken between sensor and computer. the sensor is a negative coefficient sensor average sensor range about 390 ohms warms and 2400 ohms cold engine.

SOURCE: 04 kia sorento runs poorly

Might be going super simple here but from what you have said have you checked the wiring on your sensors? If you know that one works and you swap it and its not working its very possible the wires farther up are shorted or burned somewhere.

SOURCE: Hi i get codes P0431 and P0174 on a 2002 Kia

I have tried everything, but I am coming to the conclusion that I have a bad pcv letting in too much air. The concensus of how to fix it seems to be to clean the MAF with some electical cleaner or brake cleaner. Basically, you are getting too much air into the throttle body after the MAF or a dirty MAF.

SOURCE: I have a P0011 "Camshaft Position/Bank 1 code.

OK check the CMP sensor connector for cleanliness, sometimes oil can get in and disrupt the signal transmission to the ECU. Check the wire loom continuity all the way back from the CMP to the ECU. If the error code persists remove the cam sensor, clean its tip of any debris and refit.

OHMS Resistance for temp gauge


The OHM's are different from manufacturers. Usually the work or don't. I just test the leads and heat up the sensor with a lighter. If the resistance changes, it is good. If it doesn't read or doesn't change, it is bad. Wires usually break right behind the plug. Check for continuity at the lead and about two inches back on the wire.

I have a 2000 Saturn sl 1.9L sohc. My cooling fan is not coming on. I replaced the temperature sending, which did read a temperature on my instrument cluster, before and after replacement. If I have the...


first, is/was the temp guage showing over heating? If so you should have checked/ replaced the fan temperature switch on the radiator ( or follow the fan wiring to it's location) depending on air temp, and driving conditions, the motor may not need the fan. If it's not, cover the rad with something{paper,plastic} until the guage begins to show overheat condition, then the fan should start. # DO NOT LET IT GET INTO THE RED ZONE! If you keep the reservoir closed, the radiator will **** up the coolant after warming/running, and a cool down.

They make a connector for the sender unit and they have to usually be replaced. Watch which way it goes on since they are a little cumbersome plugging back on...I prefer soldering the new connectors on too.

Temp guage sits at 0 but it runs fine and the cooling fan still kicks on and off


If all other guages are working, the coolant level is ok, and the heater is nice and warm, I'd say you need a new Coolant Temperature Sensor.

The temperature gauge on my 2002 grand prix dose


the temperature sending unit on a 97 grand prix 3800 gt(which is also the coolant temperature sensor) is not accurate. the sending unit part of this sensor only sends info to the guage on the dash. the coolant sensor part sends info to the computer of the car. it is located under thermostat and somewhat difficult to get at. i had put a brand new one in and my temperature on my dash is all over the place---even with good thermostat and properly bled system. when i hook up a scanner to my computer, the coolant sensor is sending the computer(ecu??) what seems to be the right temp. anywhere from 194 degrees to 217 when hot. the guage however on dash go from 160 to 260 in less than 2 minutes.

Temp guage dont read


U are talking about two different sending units, one is the Engine Coolant Temp sensor, the other is the temp guage sender, sounds like you have a bad thermostat, if the engine doesn't reach the proper operating temp it will set a code for the engine coolant temp sensor, and the guage will not move or move very little, replace your thermostat and both problems will go away.

Temp guage barely moves and runs rough just off idle


Try a full tune up.. get Bosch platnium+4 spark plugs and Acel wires, do the fuel filter and air filter(i suggest K&N) buy some fuel injector cleaner or use Marvel Mystery oil. The ECU could e gone but hard to diagnose if the car needs a tune up.

Temp Sensor


The temp sensor known as the engine coolant temp. sensor tells the computer if the engine is overheating and so forth and tells the injectors how much fuel to give the engine. The temp. sending unit is what controls what your guage reads. It sounds like you need the temp. sending unit. It located near the thermostat housing with a single pole connector.
