Here is the definition of the code in GM manual:
P0128 - Coolant Thermostat Below Thermostat Regulating Temperature, this indicates the engine is running cold, u need a thermostat

SOURCE: location of the coolant temperature sensor

You will find this sensor where the fat hos comes from the radiator and conects to the engine block. It would be on the housing where the thermostat is located. If it is not there you should look for a sensor that has a wire connected to it anywhere on the engine block where a water inlet is located. I hope this helps. Don't forget to rate my answer, thanks.

Trouble code p0125 which sensor do i need to replace


The code says that engine temperature was not reached to allow closed loop operation. Basically the coolant temperature sensor did not inform the ECU that the engine had reached normal running temperature. 4 things to check: 1) coolant level 2) coolant sensor cable and connection 3) coolant sensor 4) thermostat The first two are fairly easy. To check the coolant sensor (3) drain the coolant into a bucket (you can reuse it when you refill). Put a voltmeter across the connector pins on the sensor. Now immerse the end of the sensor in a hot cup of water and again measure the voltage output. You are looking for a change either up of down in response to temperature change. If you see a change the sensor is OK, if not change it for a new one. Whilst the coolant is drained take out the thermostat and drop it into a pan of simmering water. The 'stat should pop open. Take the pan off the heat and after about 5 minutes the 'stat should pop closed, if it does it is OK. If the 'stat remains open then it is faulty and this is the source of the problem in that coolant circulation is unimpeded and the engine is is being kept below operating temperature.

I have a 97 corolla, when I first start it in the morning it starts fairly easy, but when it warms up and im running errands around town, it cranks longer before it wants to restart, and its getting worse,...


The engine coolant temperature sensor could be stuck in the cold mode. This would activate the cold start injector even with the engine warm--and flood the engine with too much fuel, making for long crank times. The engine coolant temperature sensor (ECT) is usually located close to the thermostat housing. It has two wires coming from it. The coolant temperature sender for the dash gauge is not the same. It only has one wire and grounds through the engine block. It is easy to get them confused.

My temperature gage set on cold; it just begun today and it will not move pass cold.is it the temperature gage sensor and where is it located.


You didn't give any vehicle information but I would certainly check the ECT (engine Coolant Temp) sensor. They are fairly inexpensive and easy to install. Put one in and see if it fixes it. Good Luck

My radiator fan is not working on my 2006 Dodge Charger


Hi, If you have truble code check/service engine soon light on,then go to your local Autozone part store for a free scan. If not,i'm going to start with haveing you check the cooling fan relay,this can be found in the power distribution box,this can be found in the engine compartment.I would change places with another relay with the same number on it. If this takes care of it,buy a new relay and it was an easy fix. If not here's tests you will have to do as long as you have a digital volt meter.

Operation printpage_icon.gif

The Engine Coolant Temperature (ECT) sensor is used to sense engine coolant temperature. The sensor protrudes into an engine water jacket.
The ECT sensor is a two-wire Negative Thermal Coefficient (NTC) sensor. Meaning, as engine coolant temperature increases, resistance (voltage) in the sensor decreases. As temperature decreases, resistance (voltage) in the sensor increases.
The PCM compares the ECT, Intake Air Temperature (IAT), and Ambient Air Temperature (AAT) under cold start conditions. Following a start to run delay time, the sensor values are compared. If the one sensor value is not within a specified range of the other two sensors, the value is determined to be irrational

  1. Turn the ignition off.
  2. Disconnect the Engine Coolant Temperature Sensor (ECT) harness connector.
  3. Turn the ignition on.
  4. With a scan tool, read the ECT sensor voltage.
  5. The sensor voltage should be approximately 5.0 volts (plus or minus .1 volt) with the connector disconnected.
  6. Turn the ignition off.
  7. Connect a jumper wire between the (K2) Engine Coolant Temperature Sensor (ECT) signal circuit and the (K900) sensor ground circuit in the ECT harness connector.
  8. Turn the ignition on.
  9. With a scan tool, read the voltage.
  10. The sensor voltage should be approximately 0.0 volts (plus or minus .1 volt) with the jumper wire in place.
  11. If voltage is present as stated suspect faulty ECT sensor.
