RCWD21 Posted February 25, 2015 Author Share Posted February 25, 2015 That's what I was going to do next once the oxygen sensor was in. They're both OEM so I might as well replace them. Just waiting on this sensor to hurry up and get here Link to comment Share on other sites More sharing options...
SpecialWarr Posted February 27, 2015 Share Posted February 27, 2015 You may want to take close look at your wheel bearings if you can get the beast into the air. I had one the was scrapped and it was eating into my mileage a lot. I think I put up a picture in the Pictures and Videos area on here.... nervermind! Here it is: http://tapatalk.imageshack.com/v2/14/08/27/cd9b291bf2daff3e4d3fa96ccfbec2c4.jpg Link to comment Share on other sites More sharing options...
RCWD21 Posted February 27, 2015 Author Share Posted February 27, 2015 I actually checked them before I handed over the grand I paid for it. Smooth and no noise or scraping noises besides the pads on the rotors. Plus I regressed them when I installed new wheel seals and calipers once I got it home. The lockimg plate is tighten correctly and the only thing besides these sensor that I can think would be eating into my mileage is the front bushing in the control arms. The steering wheel is a tad sloppy and before I adjust the steering box I want to make sure that everything else is good. They still seem good but all the steering linkages will be replaced once I get the money. I figured for $130 for all the linkage components its a good deal to make sure I can steer straight and this monster is up to where I want it to be. I have the sensor at the shop waiting to be installed now I just need to get over this damn head cold and find a warm spot to install it. I'm ordering a new knock sensor and CTS soon to Aldo eliminate those as variables. I've been reading a lot on the smaller things and I can't find a consistant answer so I'm just going to replace them. The knock sensor is original and it literally looks like a spiderweb but it tested good before the engine was pulled so I didn't think twice about it then. Now I regret it big time. So hopefully I can snake my arm under there to unplug it Link to comment Share on other sites More sharing options...
SpecialWarr Posted February 27, 2015 Share Posted February 27, 2015 I did manage to do that but I needed a short piece of stiff steel wire sharpened at one end to get the retainer off. I just used a stainless steel mountain bike spoke that I sharpened on a grinder and bent by hand. It was still a challenge to get off. Link to comment Share on other sites More sharing options...
RCWD21 Posted February 27, 2015 Author Share Posted February 27, 2015 Did you relocate your knock sensor? If so where did you mount it to? I was thinking one of the plates on the back of the head where one of the crankcase vent lines go. But then again I'm pretty sure I could just jack up on the transfer case a bit and undo the transmission mount and that'll give me more room so I'll hopefully be able to swap sensors since I know the bolt isn't stuck because I removed it once before.

5523Pathfinder Posted February 27, 2015 Share Posted February 27, 2015 Have you tried cleaning your air flow meter? Link to comment Share on other sites More sharing options...
RCWD21 Posted February 27, 2015 Author Share Posted February 27, 2015 Yes I've cleaned it. CRC Maf cleaner. Didn't make a difference at all. Unplugged it to check to see if its functioning correctly and it went into limp mode. Link to comment Share on other sites More sharing options...
SpecialWarr Posted February 28, 2015 Share Posted February 28, 2015 I actually left the original knock sensor there as I was more interested in getting a operating engine electrical harness on. I've had no trouble with that sensor though. Link to comment Share on other sites More sharing options...
RCWD21 Posted February 28, 2015 Author Share Posted February 28, 2015 Ahh ok. I looked at an OEM harness just out of curiosity and it was almsot $1500! That's rediculous! Luckily I can pick and choose connectors and clips from wiring specialties. Link to comment Share on other sites More sharing options...
SpecialWarr Posted February 28, 2015 Share Posted February 28, 2015 I think I ordered one from www.aaanissanparts.com for $225-ish Link to comment Share on other sites More sharing options...
RCWD21 Posted March 4, 2015 Author Share Posted March 4, 2015 Alright guys, I got the sensor installed and the mpg issue has gotten WORSE! I'm at the point of just replacing every sensor to rule it out. The only code I've ever pulled from this is for the knock sensor. I have one on the bench that I just received yesterday.

ebayfish Posted March 5, 2015 Share Posted March 5, 2015 I figured some things out with mileage. I'm getting 9.57 miles per gallon so that's right at 200 miles a tank. Which is obviously way off from the normal. I don't expect amazing mileage out of this thing but I'd like at least what was advertised or maybe a little better if that's possible. Everything else is new and well within spec. Hopefully the sensor will arrive today Maybe I'm wrong, but didn't these only come with a 13 or 15 gal tank? My tank won't hold anywhere near 21 gallons (200 miles, 9.57 mpg) & I get about 250 per tank with my 15 gal tank. When I first got the truck, it needed basic maintenance & got 180ish mpg per tank.

RCWD21 Posted March 5, 2015 Author Share Posted March 5, 2015 No that was only the 2wd models. 4wd models had a 21 gallon tank Link to comment Share on other sites More sharing options...
adamzan Posted March 7, 2015 Share Posted March 7, 2015 I have never seen any pathy with anything but a 21 gallon tank. I easily fit 75+ liters in mine after riding on empty dorfor days. Link to comment Share on other sites More sharing options...
Bubbley11 Posted March 7, 2015 Share Posted March 7, 2015 ^Well you need to come take a peak at mine. Hopefully this summer I get it changed to a 21. Link to comment Share on other sites More sharing options...
Slartibartfast Posted March 7, 2015 Share Posted March 7, 2015 Mine had a 21 gallon tank judging by the amounts of gas I put in it, and I verified the new tank at close to 21 gallons (slightly more IIRC) before I put it in. The fuel pump can't completely empty the tank, so you'll never put 21 gallons in there at once. The most I've ever put in mine at once was 18 gallons.

ebayfish Posted March 7, 2015 Share Posted March 7, 2015 My sender/gauge must be off(no surprise). It shows nearly dead empty, taking 14 gal. to fill up...never pushed past E. Link to comment Share on other sites More sharing options...
RCWD21 Posted March 7, 2015 Author Share Posted March 7, 2015 Any idea why a new oxygen sensor would cause worse mileage after being replaced? Link to comment Share on other sites More sharing options...
adamzan Posted March 7, 2015 Share Posted March 7, 2015 (edited) Bad/defective part? What brand did you use? I just replaced mine after an ntk sensor lasted only 4 months. Bought it well over a year ago so no warranty. I replaced it with a bosch like factory. Edited March 7, 2015 by adamzan Link to comment Share on other sites More sharing options...
RCWD21 Posted March 7, 2015 Author Share Posted March 7, 2015 Ntk. And I figured it out. My coolant temp sensor plug came loose enough to lose contact Link to comment Share on other sites More sharing options...
adamzan Posted March 7, 2015 Share Posted March 7, 2015 Ha! Well hopefully it was just an easy fix like that. The plug form mine is missing the metal clip so I have to watch out for that as well. Did it not set an engine light? Link to comment Share on other sites More sharing options...

Precise1 Posted March 8, 2015 Share Posted March 8, 2015 Glad you found it so easily. Be interesting to see what you get now... BTW, this was my last fill up (ouch!) What? That's like $10USD... Seriously though, only $61USD or $3/gal? That's cheap! B Link to comment Share on other sites More sharing options...
SpecialWarr Posted March 8, 2015 Share Posted March 8, 2015 Yep and our prices jumped back up 25% last week so I am back to paying $100 a week in gas after a short break of paying only $80 a week! Link to comment Share on other sites More sharing options...
