Replaced mine when doing my valve cover gaskets and I can feel a noticeable difference. Shifts smoother and it feels good. I think my MPG improved as well. Definitely a plus to change this out, especially considering how cheap and easy it is.

 

Just did mine last week and a cup or so spilled out. I bought one from ebay (I know) and the adapters don't seem to fit together. Waiting on the new one from Rock Auto and hoping it all fits together.

 

Yes, did mine with engine cold and very little if anything spilled out. Definitely worth doing.

 

According to Chilton Library, the sensor's torque spec is 15.

 

Where is the engine temperature sensor on the motor located I see the pictures but not where it goes

 

I replaced my temp sensor today, but I broke the plastic clip on the harness connector. Does anyone know the part number to replace it?

 

Very good info. I just ordered a new temp sensor today. Reading above there is no need for teflon tape, sealant, etc. However is there a gasket?

 

The gasket part number is 9043012005.

 

I have a permanent OBD2 scanner connected with bluetooth. My normal operating coolant temperature is 85 degrees C / 185 degrees F. The car is at 114K miles and I recently measured 29.2 mpg at constant 55 miles per hour, flat terrain over a distance of 20 miles. I can monitor the rise of the temperature, and the opening of the thermostat.
So I will not replace my ECT for now , as it appears to be operational as it should. I do not want to mess with crumbling connectors, as I had experienced with the camshaft connector while replacing the valve cover gasket.

My suggestion would be:
1) read the coolant temperature through the OBD2 to check if it is within range.

2)If you do not have an OBD2 scanner, read the resistance of the ECT sensor on vehicle. Remove the connector and read the resistance between the pins with an ohmmeter when the engine is cold. It should read about 5Kohms to 2Kohms depending on the coolant temperature (32 degrees F to 68 degrees F). Plug the connector back. Bring the car to full operating temperature, then remove the connector and read the resistance. It should be around 200 ohms at the operating temperature of 185 degrees F.

If you have to replace the ECT sensor, make sure you do not introduce any air in the cooling system (purge the the air). Else you may end up with inaccurate coolant temperature readings at the OBD2 and possible engine overheating.

 

thanks for all the support that is available on the discussion thread , its true and I have solved the issue of P0171 system too lean bank
I ride a 2004 with 136k miles and I had the issue long ago I replaced the MAF sensor, followed by cleaning the O2 sensors, different mechanic giving me different options to try which even reached to changing the petrol tank cap.

it got finally solved once I changed the temperature sensor which was the last thing I could think off.

 

​​​​​​thanks for the post owner, i did everything and all thanks comes to this little sensor with ur guidance my dashboard is at last clean

 

Glad to hear even the older threads are very much relevant today..

This reminds me... I need to order a sensor before I do my Timing Belt next week...

 

I just replaced my temp sensor today with one from Oreilly's. (Their import direct brand that has a lifetime warranty) I'll update if my fuel mileage increases. Right now I get about 21 combined with 75% HWY and 25% CITY.

 

Don’t forget to check for coolant leaks a week later in case if you haven’t used silicon or Teflon based sealant for the threads. also, why not the OEM sensor? It is an extremely important part in 3uz-fe engine, so I would never recommend to put anything in it except for oem genuine part.

 

I'm giving this part a shot since it has a lifetime warranty and its a lot cheaper. I figure if it doesn't work out, I can just get my money back and go OEM. I was going to go Beck/Arnley actually but no one had it in stock locally and I was too eager to get at it.
