I am not sure where to turn now. I have done so much work to my D2 and I can not get rid of these O2 codes. I have replaced ALL 4, replaced a bad Cat, and intake gasket amoung other non engine things.

0134 - No Activity Bank 1 Sensor 1
0135 - Circut Malfunction Bank 1 Sensor 1
0141 - Circut Malfunction Bank 1 Sensor 2
0154 - No Activity Bank 2 Sensor 1
0155 - Circut Malfunction Bank 2 Sensor 1
0159 - Slow Response Bank 2 Sensor 2
0160 - No Detection Bank 2 Sensor 2
0161 - Heater Malfunction Bank 2 Sensor 2

Is it me, or are some of these codes condridicting suck as 0160 and 0159?

I recently cleard the codes, drove 30 miles and then rechecked them to be sure I was getting fresh codes.

I purchased these sensors off of EBay brand new, direct fit, non universal. Could I have just purchased bad sensors? When I first installed them, the CE light went off for 10 miles, came one, went off again, and then came back on and stayed on.

I'm lost, thoughts? I need to get a sticker as I have been driving with a reject for a year and a half.

 

What was the brand of the O2 Sensor? I purchased 4 Bosch sensors and didn't have any issues.

Only other thing I can think of is either a short somewhere in the harness or bad ECU.

 

Jrm, send me your number and I'll call and walk you thru what to do and check.

 

Thanks Mike! Sent.

 

It really sounds like you have bad sensors or a problem in the wiring.
What brand are they? Was there any warranty?
I've always bought NTK sensors (the Bosch I got were repackaged NTK) and have had no issues.
It might be time to look at the ETM in RAVE and go at the wiring with a multimeter. Or order new NTK sensors from Amazon. But I'd do some electrical trouble shooting first.

 

Thanks, I'm working on trying to get them replaced right now. Under the brand all it states is that "Replacement Oxygen Sensor"

When I get these replaced and if that doesn't fix it I will go back to recheck the wiring.

Thanks!!!

Yeah, those could be made in China or something awful like that. On an up-note though, sometimes Chinese parts are the same shape!!!

 

Not that was funny!

 

Now that you mention it, the O2 sensors were a bit slanted....


The company is sending me 4 new ones. See what happens form there.
