SOURCE: WHERE IS THE SENSOR LOCATED?

This is a known problem. The temp sensors go bad every so often. VW recognized this a few years back, updated the sensor and accordingly changed the colour from brown to green. oops.... They still go bad. The sensor is on the drivers side of the engine, on the back of the head in what looks like the thermostat housing. If you have a man trans there's a set of glow plugs commin out of it. This is the only temp sensor on the TDI. There's a plastic horseshoe clip (the dealer should have offer you one when you bought the sensor) you have to pop out, then wiggle the sensor until it comes out. MAKE SURE THE OLD O-RING COMES OUT, this will make instaling the new sensor much easier and will prevent your all your coolant from leaking out.... Yah, I seen it done, not good. Worst part is you can't see what you are dooing so good but its fairly simple. Good luck and happy motoring

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

P 1401 location


Codes don't have a certain location, a code means a problem has occurred in a system of the electronics of the cars fuel control or emission control system.
P1401 NISSAN - EGR Temperature SensorPossible causes- EGR Temperature Sensor harness is open or shorted
- EGR Temperature Sensor circuit poor electrical connection
- Faulty EGR Temperature Sensor
- Malfunction of EGR function, EGRC-BPT valve or EGRC-solenoid valve
- Blocked EGR passages When is the code detected?An excessively low voltage from the Exhaust Gas Recirculation (EGR) temperature sensor is sent to Engine Control Module (ECM) even when engine coolant temperature is low, or an excessively high voltage from the EGR temperature sensor is sent to ECM even when engine coolant temperature is high.
P1401 NISSAN Description The Exhaust Gas Recirculation (EGR) temperature sensor detects temperature changes in the EGR passage way. When the EGR valve opens, hot exhaust gases flow, and the temperature in the passage way changes. The EGR temperature sensor is a thermistor that modifies a voltage signal sent from the Engine Control Module (ECM). This modified signal then returns to the ECM as an input signal. As the temperature increases, EGR temperature sensor resistance decreases.
This sensor is not used to control the engine system. It is used only for the on board diagnosis

Location of engine coolant temperature sensor


Automobiles: 2000 Ford Escort ZX2 4-cylinder 2.0L MFI DOHC

NOTE
The "left" side of the engine is the driver's side.

The Engine Coolant Temperature (ECT) sensor is a thermistor (a device which changes resistance or voltage as temperature changes). The sensor detects the temperature of engine coolant and provides a corresponding signal to the PCM (Powertrain Control Module - aka "the car's computer").

The ECT sensor is mounted in the following locations (small Ford engines):

1.8L engines: in the cylinder head
1.9L engines: threaded into the heater hose inlet pipe
2.0L engines: at the left rear of the engine

2.0L Zetec Engine

(1) Partially drain the engine cooling system using a clean container. If coolant is in good condition, retain for reuse.
(2) Disconnect the battery ground cable.
(3) Disconnect the electrical wiring connector from the engine coolant temperature (ECT) sensor.
(4) Remove the retaining clip and the ECT sensor.


12_5_2011_5_38_05_pm.jpg

Fig. 1 Escort ZX2 ECT sensor - The retaining clip is removed (at the solid arrow). Withdraw ECT sensor by gently wiggling/pulling in the direction of the dashed arrow.

To install:

NOTE
Coat the ECT sensor O-ring with clean coolant prior to installation.

(1) Replace the retaining clip and the ECT sensor.
(2) Connect the electrical wiring connector from the Engine Coolant Temperature (ECT) sensor.
(3) Connect the battery ground cable.
(4) Refill the engine cooling system. An inexpensive plastic "Radiator Funnel" will help with this task.

Where is the tempurture cooling sensor located on a 1994 buick regal


The coolant temperature sensor is a thermistor mounted in the engine coolant stream. A thermistor is an electrical device that varies its resistance in relation to changes in temperature.

For 2.5L engines, the coolant temperature sensor is located on the left side of the cylinder head.

For MFI engines, the coolant temperature sensor is located on the intake manifold water jacket or near (or on) the thermostat housing.

Where is the temperature sensor for the temperature gage


Engine Temperature Sensor Operation:00116_engine_temp_sensor.jpgThis sensor monitors the temperature of the engine and sends that information to the engine control computer to regulate the amount of fuel needed - more if engine is cold and less if it's hot. The signal generated can also be sent to the temperature gauge as a visual indicator of overheating and imminent danger

I checked with autozone.com and their site says that the engine temperature sensor is not used on both engine sizes available for this vehicle.

The Coolant Temperature Sensor is used though. So maybe it has a dual purpose on your vehicle.

Coolant Temperature Sensor Operation:00113_coolant_temp_sensor.jpgThis sensor monitors the temperature of the engine and sends that information to the engine control computer to regulate the amount of fuel needed. More fuel is needed if the engine is cold; less if it's hot. If the temperature is extreme, the signal will be sent to the temperature gauge as a visual indicator of overheating and imminent danger.

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.
