'01 Pathy Fixes and Build

[TheGhost]

Decided to keep track of my work on the $1000 Pathy I just picked up in Mass. 3rd Pathfinder I've owned and this one is an absolute POS. Might've got ripped off we'll see. Not sure how long I'll keep this one, but the last one I had I made into a proper trail rig so thought I'd keep this one's saga here.

 

Anyways right of the bat its got:

- 7A draw on the battery when fuse #24/Elec B is connected (only ~0.08A thru the fuse though) and 0.03A draw with fuse 24 pulled - all with ignition off.

- rear hatch key cannot turn left (to lock) and no mechanical linkage exists on the key thing to the unlocker, plus electronics to the key thing are unplugged

- rear wiper is seized

- brake pedal easily pushes to the floor

- sway bar links are zip tied on...

- rear trailing arms are garbage

- countless dents, rust, etc.

- rear driver door will not move, stuck locked

 

Gotta be some others too. First thing is fixing the 7A draw that ruined the last battery and means pulling fuse 24 when parked.

Unfortunately Fuse 24 powers like 15 different things. And the 7A not flowing through the fuse, but somewhere else, makes me think it might be a relay that fuse 24 activates. I'm going to check the other fuses in the driver are and engine bay and then start looking at the sub-systems of Fuse 24/Elec B...

[TheGhost]

Turns out I'm an idiot. The 7A was from the headlights being on.

 

The Fuse 24/Elec B pulls 0.08A all the time, and its from the SECU. With SECU unplugged I get 0A thru fuse 24 and 0.03A at the battery which is in spec.

 

Now to track down what part of the SECU is the issue. Not sure if its the unit, or something the unit tries to power... I think it powers a lot of stuff. Unfortunately the electronic locks and interior lights don't with with SECU unplugged.

 

I'm pretty sure the FOB that came with the pathy isn't OEM as it says ASTRA on it and looks kinda funny. The FOB also doesn't work. Issue could definitley be related to an aftermarket FOB install or something. Might try find its receiver.

The FOB was tied to an aftermarket alarm system. Removed that and got a new SECU too. Neither changes fixed the 0.08A leak. At some point I'll go thru the SECU sub systems and try find where the problem is. For now though... bigger issues.

 

CEL is burnt out (oops) and reading the codes gives:

1. P1448 - ELC System 2 Fault; Vent Control Valve

2. P0455 - Evaporative emission (EVAP) system - large leak detected

3. P1145 - Intake Valve Timing Control Position Sensor (Bank 2)

4. P1140 - Water In Fuel Condition Water In Fuel Condition; Intake Valve Timing Control Position Sensor,LH Bank 1

5. P0161 - Heated oxygen sensor (HO2S) 2, bank 2, heater control - circuit malfunction O2 Sensor Heater

6. P0420 - Catalytic converter system, bank 1 - efficiency below threshold

 

Yeesh. Not sure where to start. Really hope there ain't water in the fuel Looks like at least 2 issues and maybe 3.

#1 EVAP, #2 Intake timing bank 1&2, #3 and maybe O2 sensor.

 

Looks like EVAP is a common problem on these so hopefully the forum will rescue me xD

Oh also I fixed the rear driver side door, so thats great. Also fixed up the rear hatch to where the only remaining issue is the key will not turn to the left or "unlock" position. Not sure if I'll ever be able to fix that without a $$ locksmith though.

 

So new tally:

1. Six engine codes

2. 0.08A draw thru SECU, probably some subsystem

3. rear hatch key cannot turn left (to unlock)

4. brake pedal easily pushes to the floor

5. sway bar links are zip tied on...

6. rear trailing arms are garbage.

7. rear wiper is seized

Sounds like you've got plenty to keep you busy!

 

Where are you seeing that P1140 means water in the fuel? I've never heard of a moisture sensor in a gasoline fuel system. Sounds more like both cam sensors (or their wiring) are out.

 

Try shooting some silicone spray in the rear lock, and work it around. Crap gets in there and they get cranky. Wiggle it, flush it, wiggle it some more. Might get lucky. Or take the inside trim off and see if it's actually the lock that's bound up. My door locks worked a whole lot better after I lubed the linkage they're connected to.
