Default 2001 L2 downstream o2 p0141 wire diagram/fuse help

I am throwing code P0141 for the downstream o2 sensor. However, I have no receiving 12v in the engine harness connector (D).

I do not have a Chilton or Haynes for this car.. could anyone provide me a wire diagram or at least tell me which fuse, if any, may tie into?

I am getting good readings via the scanner; however, I have no voltage (with the key turned on)

2.2 model

REWARD EXCELLENCE!

Is that a L200 I don't recall any L2 Saturn? We need a more specific model of Saturn to know what to help look for and where its at? Or put in your profile the Saturn you have and post about so that others can better assist you. If it is a 2001 Saturn L200 that sensor from Alldata says it will cost:
Oxygen Sensor
Front 24577552 $94.55
Rear 25315218 $130.50

I wasn't able to get the picture to link here but it doesn't indicate any kinda fuse for the Ox2 sensor I think in your case it might have gone bad. You might need to take it to a shop to test it.

This seems to be an L200 - a 2.2L engine. P0141 indicates the sensor heater is not working properly. Below is a wiring diagram to help.

Great Thanks!

Sorry.. 2001 L200 2.2l 4cyl.. i will fill out my profile in a minute

I have two working o2 sensors for this car.. both with proper resistance.. however, the harness I have signal A & B.. 12v ground on C.. and 0.00 on D, which is the 12v +

None in general as you isolated this problem well to loss of 12v. Wiring from the ign 10a fuse to the terminal 'D' can be broken anywhere. My guess would be either the O2 sensor connector or wire from it back to the fuse. A recommended method for finding a wire break would be using the half way point - half way between the fuse and sensor connector with a push pin to pierce insulation, probing for 12v. Since its nearly impossible to know where wiring goes, I would start at the O2 sensor connector and work back, examining the wires carefully for clues - chafing, incorrect harness routing allowing sharp edges to cut into wiring, etc.. Who knows, maybe the wire break is by the fuse panel..........

What is the wiring diagram for the downstream O2.

There are four wires colored purple, yellow, black, and orange.

On the replacement O2 sensor I have the colors are white, white, grey, black. (just purchased this car and it had no O2 sensor...)

The connector is broken so it will insert either way...

There are four O2 sensors on L300's. A pair upstream of the precats and a pair downstream of the precats. Which one and which side of the engine?

This is the downstream on bank 1 on a V6 (closes cylinder to the dash). The sensor closest to the bottom. Bank 1 Sensor 2.

Thanks!

If anyone else runs into this (for Bank 1 Sensor 2), this appears to be correct (given the unknown brand O2 sensor I have with the OEM connector - given to me by the po):

The two white wires go to: tan/wht and ppl/wht.
The grey wire goes to: blk/wht
The black wire goes to: orange

I'm assuming here that orange is 12v.

Just a guess on wiring; the two white wires are heater and the other for O2 sensor? There should be resistance between 5-12 ohms, service manual specs for OEM sensors.

It appears to be a bosch sensor. They typically seem to label the wires as so. Possibly a standard given all the after market O2s with the same colors:

white: heater
white: heater
grey: ground
black: signal

I am completely wrong here. Its the opposite. Orange goes to one of the white wires. The broken connector caused the wiring arranged backwards on mine. Flipping it around so orange went to a white wire, has solved the issue, no more codes.

What I don't get is the plug can't be plugged in the wrong way cause - I changed my O2 sensor on both our L300 front bank and the way it is designed you can't plug it together if you turn it wrong side up. When I did mine it only would go together one way at the connectors.
