do you guys know if the ECU needs to be reset?

It does not need to be reset.

Hey I'm thinking about doing this soon.

What do you torque it down to when tightening the new one up??

Do you need to put anything on the threads or just pop it in?


Thanks

Just pop it in, its brass and doesnt leak. I don't know what the torque requirements are for it, so i basically torqued the crap out of it

You want to make sure that you use the metal washer that is on the existing one, better if you can get a new one. This will stop it from leaking.

Just changed my ECT. Great improovement in gas mlieage. On a full tank, I used to go about 325 mpg before the fuel ligth came on, now its about 370 mpg.

jcrome04

I can get like 420mi to a tank.... and i want better! hahah


Looks like it's torqued to 14ft-lbs.

I can also drive more miles on a tank, but havent emptied the tank. 370miles is driven when the fuel indicator starts. But 420miles is great

jcrome04

Yeah 420 is usually a little after the light comes on. I haven't taken it too far though I don't want to run out of gas! hahaha

Oh one more question!

Is it necessary to get an OEM sensor or can I just go down to the local auto parts store and get a generic one? But then I'll probably have to do some cutting and splicing? or would it just plug right in?






I just answered my own question by looking at the photos

I allways buy OEM Lexus parts. Aftermarket or OEM ECT sensor will both fit. But the sensor can be a bit different inside with different values, and therefore the ECU can receive different values. The same with for example aftermarket O2 sensors values can be different.

jcrome04

Maybe I'll spend the extra $15 for OEM then

just had my mech do it, its a bit tougher to do on first gen than second.

i have also had him clean out my throttle body
i feel a difference in the acceleration but idk if its the throttle clean out or the sensor doing it.

i have only done it today so i havent really been able to test mpg yet
