Where is the engine temp sensor located in a 94 dodge spirit. 2.5 liter car


It doesn't show an 'engine temperature sensor' for that year, make and model
What you do have is a Coolant Temperature Sensor (there are actually one of each on other makes and models - an engine temperature sensor and a coolant {radiator fluid} sensor). Just doesn't appear to be a separate engine temp sensor for the 94 2.5. The coolant temperature sensor is the sensor that will make your temp gauge in the car move. It's location is - Under hood, center, front engine area, near distributor, mounted in driver side of cylinder head. I've attached a pic of the sensor for you.

You also have an intake air temperature sensor and an ambient air temperature sensor that tells the computer the temp in the vehicle's cabin. I can shoot you that info if your question wasn't answered above.



Good Luck & All The Best, Justin Lee

Temperature sending unit location


Hi there:
Coolant temp sensor is actually under the hose that goes from the radiator to the engine. The hose kind of loops around the power steering module.

You will probably have to take off the metal connector which connects the hose to the engine to get to the temp sensor (mine has 2 torx / star bolts) because even after taking the hose off, it's almost impossible to get to, but if you take off the metal piece, it will be very easy to get to.

Now, the temp sensor is the little bolt looking thing with a wire going into it just below.

Hope helps.

On a 2004 volvo s-40 with turbo where is the thermostat located and the engine coolant temperature sensor thanks


Hi!!

Thermostat location in 5 cil. engines, temp sensor is located just right or upper arrow in picture. I've included a picture of temp sensor and installation instruccions.

Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

  1. Drain the engine coolant.
  2. Disconnect the ground cable of battery.
  3. Remove the electrical connector from the sensor.
  4. Remove the coolant temperature sensor.

To install:
  1. Apply sealant to sensor threads. Install the sensor and tighten to 15-29 ft. lbs. (20-39 Nm).
  2. Attach electrical connector to sensor.
  3. Connect the ground cable of battery.
  4. Refill the coolant.

Volvo Radiator, Thermostat and Sensors Your cooling system's temperature controls include all coolant temperature sensors, Volvo thermostat, Volvo radiator or expansion tank cap, cooling fan(s) and fan clutch (if equipped). These cooling system parts function primarily independent of the engine but control the engine either through cooling or by sending control signals to your Volvo's electronic systems.
The Volvo thermostat is a spring-loaded valve that opens and closes based on the temperature of the coolant flowing through it. A high temperature reading followed by a drop to normal temperature (or a continuously low temperature) is a common first sign of a sticking Volvo thermostat. However, many other conditions may cause these symptoms, so you need to know how to eliminate each possibility.
The Volvo radiator or expansion tank cap is also a spring-loaded valve reacting to system pressure. It serves to maintain proper system coolant level at predetermined pressures. It must always be replaced with an exact replacement cap with the same pressure setting. Never use other caps except for short-term emergencies!
A belt-driven fan blade for pulling air through the Volvo radiator is usually on the Volvo water pump pulley and should have a fan clutch to control it. The fan clutch allows the fan to turn with the belt at low engine speed and "free-wheel" at higher speeds. A bad fan clutch either doesn't allow the fan to spin at low speed (overheating in traffic) or doesn't allow it to free-wheel at high speed (potential overheating on highway or reduced gas mileage).
An electric fan can be either by itself (usually front-wheel drive) or auxiliary (used with a mechanical fan). Both types are controlled via a temperature sensor - in the Volvo radiator or upper Volvo radiator hose or on the Volvo thermostat or Volvo water pump housing. This sensor is usually an on/off type switch with a fixed temperature setting. (Some vehicles may have 2-3 settings for multi-speed fans.) This sensor is commonly called an "auxilliary fan switch".
Other common temperature sensors are: 1) gauge sender (variable output); 2) warning light sender (on/off type); 3) lambda and/or fuel injection sensor(s) (variable to control fuel injection settings); 4) thermo-time switch (cold start valve control). Your Volvo may have other sensors as well.
Temperature control is critical to both performance and emission control. Unfortunately, this system is the most difficult to troubleshoot without proper equipment and diagrams. It's even more difficult with computers that adjust timing, idle speed, vacuum and fuel delivery automatically to make up for potentially faulty temperature sensor signals.
Maintenance of your cooling system sensors is virtually impossible since there's nothing really to "maintain". Keeping them clean both internally (coolant replacement) and externally (engine cleaning) is the best way to ensure trouble-free driving. Checking and replacing all parts at the factory-recommended time or mileage limits helps as well

That is a code meaning that your coolant temperature is too low below threshold. 9 times out of 10, you need a new sensor. It is the CTS (coolant temp sensor), or called your engine temperature sensor. Hope thats helpful
