87Fathpinder Posted May 23, 2013 Share Posted May 23, 2013 (edited) I was looking at this: http://www.troublecodes.net/Nissan/pre88nssn.shtmland according to this my 'finder should have a dial on the ecu but mine has a toggle switch. Does my truck have the wrong ecu in it? and if not how do I fix a code 42 (Fuel temp sensor I think)? In the past it has given the codes 43, then 44, now 42. I don't know what to do.It's worth mentioning that when I fixed the code 43(tps?) I ended up removing the tbi to replace the broken tps bolts. anyway, the egr port was clogged solid with carbon so naturally I cleared that out. I put everything back together the way it was, but now the truck bucks when I try to rev passed 2000 rpm's... could that be from the egr valve or the code 42? I'm getting really frustrated with all of this and i'm about to give up on the Pathfinder I love because of it.

Rebel526 Posted May 23, 2013 Share Posted May 23, 2013 http://www.nissanpathfinders.net/forum/topic/21-ecu-self-diagnostics-for-87-95-pathfinder/ Yep, you have the right ECU. Check your plugs and wiring. I'm betting you have a bad connection somewhere Link to comment Share on other sites More sharing options...
87Fathpinder Posted May 23, 2013 Author Share Posted May 23, 2013 (edited) Does anyone have any idea where the fuel temp sensor is? I can't seem to locate it anywhere, and it's not screwed into the side of my fuel pressure regulator. Oh, and it also idles between 1000 and 1500 rpm...
