Please help.

[1.8dubbin]

17522 and 17526 is what I need help with. disregard the others.So I have this Scan I hope I can get some help. It's been on forever and I can't seem to fix it..
I have replaced the sensor multiple times, and replaced the ECM once. I then checked all the wiring and it was fine.. Any help is greatly appreciated.

So O2 sensors? What exhaust do you have? If you have a aftermarket steel exhaust that isn't as restricted that would probably be why... as heat will sit on steel longer and heat differently. Also will measure different due to high flow.

Just a thought really. Is there a fix? /shrug maybe if you flash your car. I know I wonder if I could find REVO near me I'd be able to get rid of my CEL by going to 2 or 2+

I have a 3 inch Eurojet exhaust with an o2 spacer.

[path0s]

That may be it right there... O2 sensors are finicky. temps pressure etc. Did this start when you got the exhaust.

Those are both circuit codes that indicate high resistance/open circuit, as if the sensor was unplugged. I can't see a big exhaust or spacer causing these codes.

Check the connection. Verify ALL the wires on the car side. Are you using OE or OE-style Bosch sensors?

[path0s]

Well see that's what I was wondering as well seeing high Resistance. I'm all out of thoughts after that. So you replaced them before I'm guessing?

A post about the same issue. But on there hand check your wiring again. Take a rag/cloth that is able to catch on cuts/scrapes etc and run it along the wire to see if it catches any Knicks of some sort.

I go with anony00GT.
Seems like a wiring problem with high resistance.
Check all wires to the B1S2 sensor again and load test and voltage drop the wires.
Also make sure you have power and ground load tested to the heater circuit.
Also check the ECU connector for corrosion seeing a lot of that lately as these get older.

Keep in mind the O2 heater circuit known to short out and burn up the ECU pedal circuit destroying the ECU on 1.8T motors. Good idea to fuse the heater circuit to avoid this.

Good Luck

Probably right due to high Res. Just wasn't sure seeing as he said he checked wires. I hate wiring... more of a structural Guy. Keep us posted and good luck.

Change the OXS sensors immediately!

Add a fuse for the heater circuit if you know how.
This could cause an unsafe driving condition at any moment.

Soon you will burn down an ecu.

Best,

This is true as well. Forgot about the potential ECU damage.

Adding a heater circuit fuse is a darn good idea too.

I will double check the wiring. I'm using OEM

I have 3 or 4 times, once after the new ECU.

I haven't a clue how but I will see if I can find some help. I hope it didn't fry this ECU to.

Thanks everyone for all the input

depending on the year there is a power steering pressure sensor that leaks internlly and causes a short across the o2 taking out the ecm. so if you ever had oil in those connectors and you just replace the o2, you will still need to clean/replace the rest of the harness. food for thought...

[Jack@European Parts]

Brake clean is your friend.

Not if its fused.

Every time I have pulled apart the connecters they are clean. No oil, corrosion etc..

Why exactly ha?

[Jack@European Parts]

If its clean don't worry about it.

[1.8dubbin]

Still no clue on how to fix this issue. Anyone have any ideas/help?

[Jack@European Parts]

You should send me your ecu for update and to be checked on the bench to make sure its not FUBAR.
