I got the engine lamp in the dash. I used my IIDtool to retreive the error codes. I reset them and the reappear in short time. I understand that this has something to do with oxygen sensors, but I need help ion understanding what is wrong. Is one of the sensors malfunctioning or are this a symptom of sometning else wrong?

Error codes:
P0151-1A(E
P0051-00(AA) 2006 Supercharged

So, an update and a call for any help:

I changed all 4 lambda sensors, but the engine lamp came back. Pretty soon. I have been off for a while but are now back. I retrieved the code and at least it now tells me what sensor have a problem:

P0160-00(E8 ) Heated exhaust gas oxygen sensor - circuit no activity detected (bank 2, sensor 2)

What do you think? Wiring/Connector? Bad sensor? 2006 Supercharged

Another update:

I swapped the two rear sensors around to see if the problem followed the sensor. It did not, I retrieved the exact same code after the swap. The problem seem to be intermittent, if i reset it may take a while before the code reappears.

There may be a problem with the wiring to the sensor? I read somewhere on the board about a 30A fuses in the engine bay. Anyone know about this? Hard to think a blown fuse might be intermittent though...

I did measure between the pins with ignition on. There are 3 pins, I got 5V between 2 of them, 12V between two and 0V between 2. The same on both sides. 2006 Supercharged

Hi Ian928.

I've got the same error codes as you mentioned above. Did you resolve this issue please?

And, if so, how?

Cheers.

I did not manage to resolve it. It does not affect the car other than creating the engine lamp, this has made me not prioritizing the problem.

My plan was to try to measure values for both sensors from connectors in the box in the engine bay, that way I could test both sensor and wiring. 2006 Supercharged

OK, Thank you.
