Rockauto shows the NTK 23553 and Bosch 12009 having a white body with black boot. Amazon shows the NTK having a gold body, and the Bosch silver, but what they show is not always what you get, like the local parts stores. Rockauto (and Amazon) shows the Walker 25023501 having a black body. Looking up Crown 53004245 takes me back to the black bodied Walker. But Quadratec shows the same Crown 53004245 (Crown 55120.08) with a white body.

Now i am confused lol. I hope you find the right one.

Just go to the dealer and pay his price. Problem solved.

Amazon shows white body for crown 53004245. as does quadratech. But all sites I seen that shows the 53004245 shows it wrapped with a rubber band and not in a box. Will see tomorrow when it shows up. Will post the results.

Real strange as to what's going on... for sure

Dealer has o2 sensors for renix? Thought dealerships only carried parts for vehicle 6 or 8 years back. If the 53004245 is incorrect will have to see if the dealer actually has them for renix.

Oh, sorry. I got this thread mixed up with a thread about Crank Sensors. I've been going back and forth between them and got lost.


Still, it couldn't hurt to ask.... Phone calls are cheap.

Note from DJ
When you check for parasitic draw with your new O2 sensor if it is still present; try removing the jumper wire between the two relays then check again.

Also if it is not the correct sensor; I may have a lead for where to by the correct one.

randy61

Will do just for the heck of it.
The original sensor and the junkyard sensors did not cause a draw. That's the strange thing.
The other sensors I got had a built in heater, (Zerconia). The Titania sensors are heated through the relay.
Thinking that there has been a manufacture mixup.
In the youtube video I posted the individual bought a sensor for his 90 xj from Walker. It was the correct sensor but the box had a different sensor pictured.
That video was made in 2012, something has since changed

Failed yet again.
The Crown o2 sensor #53004245 came today.
Silver body, 1 black wire and 2 white wires.
Parasitic draw 1.37 amps. It has a built in heater, it got warm all by its self just by plugging it in.
Dealership is next but doubt it though.
It's back to the junkyards.

The correct sensor was used on only 1% of vehicles as per the link above on sensors.
Jeep was a bit different because they used a 5v reference through the relay.
All the sensors made today are built in heaters... Zerconia.

The NTKs used to work fine. Somehow the manufacturer began mis-boxing them. Do the ohms test at the junkyard.

randy61

I brought home 3.
2 tested 0L.
3rd one tested 3.5. Been using that one. Then I was experiencing stalling at stop lights. Then tested it after that happened and it now tests at 1160, if that's possible.
This time when I go I will take your advice and take my voltmeter. Didn't think of doing that when I bought them.
After the Walker sensor drained my battery over night I emailed them about it. The guy who replied said he use to be the service manager at a jeep dealership, (sound familiar), he told me I had a wiring issue.
But my wiring tests fine. Its just the sensors, like you said must be mis-boxed.
When I tested the Crown sensor it tested 4 ohms

cruiser54

IIRC, it's 8 to 13 ohms.

I suppose that the jeep renix is soon to be a buried relic just as soon as the oxygen sensor takes a crap. Or the engine, computer and harness is replaced with newer year

I Contacted sales@FactoryChryslerJeepParts
They said that the part is discontinued and cannot supply any longer.

Has anyone replaced their oxygen sensor on their 87-90 jeep Cherokee within the last year?
What brand did do you get?
What colors were the wires?
What was the body of the sensor made with, porcelain or metal?

randy61

FSM says 5-7 ohms

Dave51

You been at this for a year?

What are the part numbers of your fuel pump and oxygen sensor relays?

You have a parasitic draw even with the relay out?

Which relay terminal #s are you jumping?

Dave51

Wow you're in the big O2 sensor thread too?
