Hi all!

Long time lurker...first time poster here

So right to the details
My 92 is getting **** poor mileage and after recieving my code reader in the mail yesterday i believe it to be the darn ECT after getting a 118 code, along with some pesky EGR codes as well, but ignoring those atm.
Question is, i am trying to determine which part to pick up at the local store. Here is the part I believe it to be and am basically just needing confirmation this is correct http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Coolant-Temperature-Sensor-BWD_3461785-P_290_R|GRPSENSAMS_575653328___#
Thanks for your help

Chad

If the above link doesn't work, can you please find the correct part at Advance Auto...Thanks again

Edit:
Crap...forgot...its a 92 2WD 5.0

 

That looks like the one....

 

Your parts search inicates the parts for a 93', but I don't think it matters for that part. Your doing your E/C scans w/ the engine at norm. op. temp. right? Using the #3145? Beats counting flashes for $22. It tells you if the codes are O, R, or C. It really helps denoting which type it is. Not so much on this one, but when you want to deal w/ the EGR codes. If you've never removed, cleaned the EGR & mount portways & inspected it's diaphram, this would be a good time.

 

I double checked...i have the 92 listed as my vehicle on Advance's website...so...not sure where the 93 is coming from..? /shrug
You know its my fault for not verifying that the truck was indeed warmed fully, tho i did leave it running for a good 5 mins before starting the test...so i just assumed. Even so...the 118 code showed up on the KOEO self test and continuous memory test...then again on the KOER
The KOER test defaulted to the 998 Failure mode and then spit out the 118 code once again...so I can only really assume that sensor is bad.

A side question here...the O2 sensor...should i look into replacing this as well? I did not receive a code for it, but without really knowing how a 02 sensor works. My thought is its been "choking" on this rich mixture for quite some time...can it become "clogged"?

 

You can remove & douche them w/ Electronic Contact cleaner. You should replace replace them by 60k, because they are less accurate & their switch speed has reduced considerably. Or you can pay for it at the gas pump! I toss mine at 35K. Which is one reason my 87'302 a/t gets 17/23 mpg. Always disconnect the battery for 5 mins. after replacing a sensor to clear the KAM (keep alive memory), which is different from Continuous memory.

As in"Profusely irrigate w/o the bag"!

 

Oh man...i feel foolish...
So i went out and took a look under the hood to verify wiring and sensor placement to see what tools i might need.
Lo and behold...the ECT wasn't even plugged in.
So for the last year or so (since i replaced the thermostat anyways) it hasn't even been plugged in.
Needless to say, after plugging it in...clearing codes...i now get a 111...systems pass!
Not sure if i will see a mileage increase or if the EGR codes will pop up again, but will keep an eye on it since i got this new code reader.
Thanks for your guys help, and i will for sure be posting again.

 

Clearing the codes doesn't clear the KAM, so it can rebuild from scratch w/ all sensors input. Disconnect the Battery for 5 mins. Also, Seafoam the combustion chambers. They're loaded up from running over rich.

 

yep that will do the poor mileage...it thinks its always running cold...

or hot just depends how the ECM decided where it wanted to be...
