Could be thermostat stuck open or temperature sensor.Any codes?

Posted on Dec 09, 2016

Testimonial: "yes i have the check engine light on took it to autozone and the code which i forgot said it needs a fuel vapor detection pump to be replaced. i noticed that the temp gauge is not moving much pass the cold but we have good heat in the cabin"

Location of the coolant temperature sensor on hyundai accent 2002


There are normally two, one with one wire which is for the temp gauge, and one with 2 wires which speaks to the ECU. The later one is usually near the thermostat housing or in the cylinder head nearby. If unsure, get the part from parts store and ask if they can show the location chart.

2000 hyundai accent runs good though,when it gets up to temp. the car shuts off ,when it gets cold again it starts right back up whats my problem has a new radiator in it


car shuts off when temp, gets to normal--- causes: low coolant, failing coolant temp. sensor, air in water pump, failed radiator fan, kinked heater hose, check the coolant temp. sensor first.

The check enging light comes on then goes off. I foud out the code po118 engine coolant temp circut high input. is it the coolant temp sensor. if so how do I replace it. It is on a 2004 jetta tdi


According to Autozone.com:

Because ECT (engine coolant temperature) sensor procedures vary depending upon their location, first locate the part. You may need to partially drain the engine coolant to prevent coolant spillage.
  • Disconnect the negative battery cable.
  • Unplug the ECT.
  • Then, unscrew it.
  • Reverse the removal procedures to install the new part.
  • Connect the negative battery cable to the battery.

Fig. Remove the coolant temperature sensor
The coolant temperature gauge sensor is a temperature-variable resistor, or thermistor. As coolant temperature increases, the resistance of the sensor decreases or decreases, depending on the type of sensor.
A1 and A2 platforms use a different type of circuit that A3 vehicles. On A1 and A2 vehicles, the circuit is a "resistance to ground" type. A3 vehicles use a "variable voltage" type, where a voltage is supplied to the sensor. Because of the circuitry design on A3 vehicles, testing of the coolant temperature gauge is limited.
The engine coolant temperature gauge uses a heat sensitive sending unit to transmit an electrical signal to the gauge. The sending unit is a heat sensitive variable resistor that is located on or near to the cylinder head and threads into an engine coolant passage. The sensors are a Negative Temperature Coefficient (NTC) type. As the temperature increases, the electrical resistance of the sensor decreases. As the coolant temperature changes, so does the resistance of the sensor. The gauge is calibrated within the operating range of the sensor and interprets the resistance value to display the coolant temperature.
Beginning with model year 1994, the engine coolant gauge and the Engine Control Module (ECM) temperature sensors were combined into one sensor with 4 terminals. The basic operation remains the same in that their resistance decreases as the coolant temperature increases, however the actual resistance values of the 2 sensor circuits are different. The electrical connector of the 4-wire terminal sensor ( 1 and 2 ) is keyed to prevent improper connection of the sensor's electrical circuit.

My 2003 hyundai accent is over heating I replaced the thermostat the belts are fine Im not sure what else it could be


If it only overheats while stopped or when driving slowly then check to see if your radiator fan is coming on. If not check the radiator fan fuse, temperature switch, relay, and the fan motor itself.

If it is consuming radiator coolant or is blowing steam out of the tailpipe then consider a blown head gasket as your problem. The engine oil may or may not look milky in color if the head gasket is leaking.

did you install the thermostat pointing in the correct direction? Is the radiator cap in good shape? Check for correct coolant level. The radiator will continue to draw in coolant from the reservior for many heat cool cycles after it has been opened.

And lastly could the temp gauge be reading high? Possible temperature sensor.

There are two sensors connected to the thermostat housing and i need to know which sensor is which and what they control. on cold days i cant get started


The larger of the two is the coolant temperature sensor. The other is the actual gauge temperature sensor. The coolant temp. sensor gives information to the cars computor & when the car reaches a predetermined temperature, the computor changes the ignition timing allowing the car to run at normal operation temperature settings. The temperature sensor gives info to the dash board gauge &/or temp. warning light. The reason you can't start on cold days is that your coolant temp. sensor is stuck in advanced mode & the timing is to far advanced . To remedy this problem change the coolant sensor. Good luck!

Seems to me it's the engine coolant temperature sensor or the connecting wire to it. Some Model/Year (MY) hyundai's have TWO (2) temperature sensors.. one for the instrument panel/gauge, the other strictly used by the ECU (Engine Control Unit)... if this sensor goes bad, it sends the wrong data/signal to the ECU and this can affect engine performance.

They tell me I need a coolant temperature sensor


you might have 2 coolant sensors one for the gauge and one for pcm, and if you stop by a part store like autozone they will give you a print out of locations of one or both. did they tell you that you only had one ? ask the part store how many they are showing for your car when you go they will tell you. then find out which one they want you to replace

1997 Hyundai Elantra has heat but temp gauge does not rise.


If the coolant is below a certain level, the temperature sensor will not read anything and the temp gauge will not rise. Replace the cap, and check that you have enough coolant in the system. If this does not solve the problem, you will need to test/troubleshoot the coolant temperature sensor.
