Can i spray pb blaster on the sensor while the pipe is still hot? Or will that shit start a fire?

[wed3k]

It would be pointless, the heat would make it evaporate

Unless you use Seafoam Deep Creep...

Crap! This post is way too long just for error code 43.

Crap! This post is way too long just for error code 43. Anyways, my 02 sensor is not even two years old, its a denso. So what else can cause #43 to go off?

In Ryan’s case it was his O2 sensor. He replaced it and the code went away.

IIRC a code 43 can also be caused by a fuel delivery problem. Like an FPR or Fuel pump. This is if my memory serves me right. I would do a search just to be sure. At the time of this thread I found plenty of info by searching "code 43".

Have you pulled your o2 sensor and inspected it? Running extremely rich or burning oil can foul a sensor easily.

Well!
I was dealing with multiple codes yesterday: 43 & 17
D4 light:14,1,2,7 & 8
I reset my base ignition with in spec, it was idleling 1500 RPM, got town to 700 RPM's, whick is cosider the norm. My timing was dead on, so I then pulled #10 back up radio fuse to clear out the codes. I then went out for a test drive and the check enginge light came back on. Pulled the solo code from the TCU and it pop up as #43, all the other codes, including the D4, cleared out.
If Im lucky, 02 sensor seems an E-Z fix for a #43, if not, Im so bunk, Im dreading and alternative issue here. Im just covering my bassis here. I do the reasearch on other possible leads and post up my finding and resolution.

I have not pulled it yet, what do look for?

[RyanD]

Do the o2 sensor first. They do wear out. It is easy to replace. I even made a diy. If that does not fix it try replacing the fpr

[H311RA151N]

^^^ That would be what I would suggest also.

K, im gonna lean towards the o2 sensor, u just got to wait for payday. I also have a slight sluggish, slight power lost wen I accell. It does not happend all the time. Is this issue related or am I looking at another unrelated technical problem?

[RyanD]

i would also say that could be the o2 problem
