jwestpnw Posted February 19, 2008 Share Posted February 19, 2008 So I'm thinking of replacing my ECT sensor and I open up the hood to see how the access was and it's just not there. I have a 98' and the shop manual I have is for a 97' so could the ECT sensor be in a different place? Any help would be great. Link to comment Share on other sites More sharing options...

Also, please explain what you mean by "it's just not there". Where are you looking? Link to comment Share on other sites More sharing options...

Where are you looking? I think this is where it should be, right? Basically I was just messing around and noticed this. Link to comment Share on other sites More sharing options...
gwhunt23 Posted February 20, 2008 Share Posted February 20, 2008 (edited) See that thing right beneath your red circle with the gold colored bolt and black connector and wire? That's your ECT sensor - just changed mine. You'll probably need a deep 3/4" socket even though it's not an American car. ( 3/4" roughly equals 19mm ) Edited February 20, 2008 by gwhunt23 Link to comment Share on other sites More sharing options...

You can see that there are 2 sensors right next to one another. Then if you compare to the pic of mine you can see that I only have one. Any idea what the other one is,was,or should be? oh, and the sensor in the color photo is only like a 12mm size.

Hmm that's odd. I have a '99 so perhaps that accounts for the small differences. I'd say your best bet is to take out the the sensor and if you see coolant, then that's probably it. Do it when the engine is cold and you won't have much coolant spill. Compare the sensor you just took out with the new one and go from there. Perhaps someone else can chime in with the details of doing this on a '97 specifically. Edited February 20, 2008 by gwhunt23 Link to comment Share on other sites More sharing options...
XPLORx4 Posted February 20, 2008 Share Posted February 20, 2008 (edited) It turns out that the ECT sensor is in a different location on the '98. Click here for the 1998 Pathfinder "EC" section from the FSM. It looks like the ECT is under the passenger-side fuel rail.
