QXFoe

02 QX4 has this code and I've tested the front crank sensor/variable valve timing sensor and the two solenoids. Also tested the cam sensor. Found how to test via google and YouTube. There have been a couple forum archives that suggest switching the valve timing sensors but I can't find passenger side to save my life. Any help would be appreciated of course. Pics would be great but I'm lost as to what to do.

Wow! That is super cheap. Where are you located?! I only gave 1k for the truck but it has three codes all are catalytic converter and o2 sensor, rear main leaking and strong smell of gas from exhaust. I got really worried after cranking and seeing a lot of vapor from exhaust and what I thought was a great bit of water coming from exhaust but radiator is full so maybe I'll be ok

I finally got to degrease the engine also to look for the source of an oil leak. Dang rear main...how terrible is it to change in these?

Yeah it's not really a DD. Pretty much won't strand me e en if the solenoid fails but you're right I'll probably at least look at it before replacing just to make sure. Hate to throw parts at something that hasn't been probably troubleshot first.

Thank y'all for all the replies! I may just let it fail completely. Or may try to take it off and disassemble to see if I can clean it up. Maybe recondition the contacts.

That's really smart. I didn't think to ohm the contacts. Should be able to clean them. If they ohm high. I've read terrible thins about putting new starters/solenoids on the QX4. Seems to have been a faulty component out of the box. So I hate to drop x amount of dollars only to have a fail on a new one. Any suggested brands? There's a remy online for 60$ but then I think AC Delco is 120$. Big difference. It's an old truck lol

Like maybe funk is between the contacts or something?

I have a meter so I should see 12v at the hot lug to ground and then 0 across the lugs without engaging the coil, and 12v again once someone turns key right? But my issue also is that it works most of the time. Pretty aggravating. It seems if the coil was open it would never engage and would magically start working again. But I hear the click, so guess maybe the contact isn't "closing" good enough?

I don't know how long it's been acting up but I'm thinking it may be the solenoid I'm hearing? And it's not passing the juice to engage the starter perhaps?

I guess that's more my issue than anything is it cranks right up after a few tries so it's hard to troubleshoot. If I tap and it starts there was a good chance it would start anyway.

I just got a 2002 QX4 and the owner told me it will sometimes click and not start. I read where it could be the Neutral park switch but to troubleshoot it the next time it did it, place in neutral and try. I did and it still wouldn't start. Looked around for a solution but didn't come up with much. Truck has 165k and runs like a dang top otherwise although having three codes of which one is an O2 sensor of course. I am new here and you'll most likely see me quite a bit. It's my first pathfinder/QX4 but I buy and sell often and join forums for each model to learn about them and interact with fellow owners. Thanks for looking and maybe someone has an ide where to start.
