It is a 2 wire seneor under the throttle body. You will have to remove the air breather and it will be a brass/black plastic sensor. A 3/4 socket will fit it.Good Luck

My Chevy Venture 1999 when I drived the temperature was normally, but when I stay the temperature was hot. I changed the termosthator but the problem is continually.


Check the coolant reservoir and the radiator for proper coolant level. If low you probably have a leaking intake gasket or possibly a head gasket leak. The intake leak will be visible on either end of the intake manifold, located at the very top portion of the engine. The head gasket usually shows up at the rear head, nearest the belt. You could have a water pump leaking and this would show coolant on the ground under the right front of the engine, more so when the engine is running. They are very common for all 3 problems.

My 97 chevy venture has been overheating and losing coolant after driving for only 3 to 5 miles. I recently changed out the thermastat, flushed the radiator and added new coolant, changed the spark plugs,...


You will need to replace your heater core as I bet if you lift up the carpet you will find it damp because thats where you are loosing the fluid. It is undectable unless you lift up the carpet and the foam padding. Also change out your Coolant temperature sensor under the throttlebody. You may also have a bad water pump and or (as you face the the engine) the upper right plastic part of the Radiator may be cracked leaking only when hot.

Never use a stop leak additive especially to the Venture; it has an inferior coolant system. One other item is you may have installed an either overrated temperature or underrated Thermostat causing open and closure issues....The Venture needs the precisely rated Thermostat. Let me know how you fare.

I have a 2004 Chevy Impala. As I was driving home yesterday I had the heater on full blast - temp outside appx. 60. The check engine light came on and I had a P0128 code. Could this be due to keeping...


This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125

In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle.


A code P0128 may mean that one or more of the following has happened:

  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor

Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:

  • Verify coolant strength & level
  • Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
  • Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
  • Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
  • If the above items check out good, replace the thermostat

I hope this helps a bit!

Fifteen minutes! you have bigger problems than only the fans the fans are controlled by a thermo switch that is heated by the coolant, If you have no coolant the sensor cannot activate But fifteen minutes seems like you may have a headgasket problem and steam cannot heat the coolant sensor.OperationNotesThe electric cooling fan operates when the engine cooling temperature exceeds a certain value. The cooling fan on this engine is controlled by the Powertrain Control Module (PCM) . The PCM turns the cooling fan ON by grounding the coil of the cooling fan relays when certain conditions are met. When the A/C is requested, the cooling fan will also be turned ON.

Power for the cooling fan motors are supplied through Maxifuses(R). The cooling fan relays are energized when current flows from the fuses in the Underhood Accessory Wiring Junction Block, and through the relay coils to ground through the PCM. The Coolant Fan 1 Relay Control Circuit is grounded for low speed fans operation. During low speed fans operation, both fans run at a slow speed. The Coolant Fan 1 Relay Control Circuit is grounded for high speed operation. During high speed fans operation, both fans run at high speed.

IMPORTANT: When certain Diagnostic Trouble Codes (DTCs) are present, the PCM may command the cooling fans to run all the time. Perform the A Powertrain On Board Diagnostic (OBD) System Check prior to diagnosing the engine cooling fans.

For more information regarding the Charging System, refer to Charging System Description , and Charging System Circuit Description in Starting and Charging.

If a problem that involves the low speed cooling fan relay control circuit exists, DTC P0480 Cooling Fan Relay 1 Control Circuit should set. If the problem affects the high speed cooling fan relay control circuit, DTC P0481 Cooling Fan Relay 2 Control Circuit should set. A problem with the ECT sensor should set DTC P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low Voltage, DTC P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Voltage, DTC P1114 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent Low Voltage, DTC P1115 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent High Voltage. Any of these DTCs will affect cooling fan operation and should be diagnosed before using the Electric Cooling Fan Diagnosis.

For more information regarding the Cooling System refer to Engine Cooling Fan Description - Electric, and Cooling System Description in Cooling System.


Here is the electrical schematic and how it all is suppose to work,
