89 pathfinder 02 sensor question

bestblinds · Dec 28th, 2004, 07:07 PM

may I ask for a solution to my problem.1989 6 cyl. 5 sp/4wd made on 3/89. listing for replacement 02 sensor is bosch 15207. It has 3 wires on each end. OEM has 3 wires at 02 sensor and a fourth wire factory spliced into black wire at connector. This is a white wire from a single wire plug right next to the 02 connector.This spliced in wire goes to the black 02 harness connection and becomes a fatter black wire untill it gets close to the sensor at exhaust and then thins. Should I splice this white wire into the bosch 15207 3 wire harness? This bosch sensor comes in a bosch box but is really made by NTK(NGK) I was hesitant to splice because I didn't see the bosch wires fatten in the harness. Thank you for your help.

I had the wrong sensor. Before 8/89 production date OE sensors are Walker 250-24514 Standard sg494 Kem 138-774 these are the only 3 I have found with 4 wires on one end and 3 on sensor end with 2 connections at harness end. After 8/89 production sensors are easily available. 3 wires on each end.

I bet $5 that one of the wires just has a jumper from it to the other harness for ECU data and the 3-wire O2 sensor is the same dang thing. I'd really like to find out about that, actually. Paying $135 for an OEM Nissan sensor kicks my ass.

I had to pay 150.00 for the Kem but I bet your right. I also have a 02 frontier and the tie rod end went bad. Nissan won't sell just the end I had to buy both tie rods/pitman arm/and entire assembly.350+ bucks.No aftermarket availablity yet. I even wrote to Japan complaining about this and recieved a call from them saying they couldn't help me with this. Truck has 73000 on it already. I guess this is just one more of the things we have to put up with Nissans.Blower motor resistors/frame rust/oil filters hard to get at/ECU readings under seats/Plastic fittings that dry out and crack.But in 1 million pus miles on 5 trucks no bad engines or trannys. Never even changed a clutch.

MOOG steering replacement part numbers for tie rods, 2002 Frontier:
#ES3661: Outer tie rod end
#ES3660: Inner tie rod end

They've been making them for a while, man. How hard did you look? I found these on Rockauto.com for $35.79 each.

ACDelco part numbers:
#45A0830: Outer tie rod end kit: $29.79
#45A0829: Inner tie rod end kit: $32.79

Hope that helps if it happens again...
