Update on fault codes
« on: 26 August 2008, 12:15:14 »
Since Kev attacked my EGR with some cleaning solvent, the EGR fault code has gone.

I've cleared the codes and done a few runs, and the only codes I get now, are

16
38

(Lambda one incorrect voltage / open circuit).

Maybe a duff o2 sensor too?
I was considering swapping them over, and seeing if the fault code goes to the other side...

Well 16 is a drivers side knock sensor error......which is not good.

I would concentrate on this one first so check the knock sensor cable is not trapped or damaged any where.

Bloody hell so it is, I thought it was the open circuit code.
I'll go sit in the corner :(

Knock sensor - is that accessible from underneith? I can't really recall...

No, its an alternator off job to get at (easy enough).

Seen them get damaged and trapped by poorly fitted alternators and aux belt tensioners.

I routed the wire myself when I did the aux belt tensioner, I recall taking extra care not to trap it.

If I find a damaged wire can I repair with solder/heatshrink, or do I need to replace the complete sensor?

Just had a peek. There were no nicks in the wire - it's just broken clean off ;D

Can't get to the other half of the wire though, so may be an alternator off job anyhow. I'll try the aux belt tensioner first and see if I can get access then...

Forget it, take the alternator off......its as easy to do as removing the aux tensioner anyway.

All I needed to do was take out top bolt and loosen lower bolt and swung the alternator out of the way.  Good access to the sensor this way

The good news is if you are stuck you can repair the cable on the knock sensor! I rejoined the chafed cable, soldered it and then sealed it with shrinkseal tube which I had put onto the cable prior to joining it. I did and it is still working to this day
Remenber to re-route the cable if it is likely to catch again.

just as easy? Alternator easy? I must have been doing something seriously wrong with my old cdx then. I found it a complete pig? Problem being the nuts on the back of the long bolts where not captive, and access the back was restricted to say the least. What was i doing wrong?

Dont know, did one in 45 minutes the other day for a forum member and we had to fight to get the aux belt off because the alternator had not been fitted correctly!

Yes i saw that thread, when i did myn, i was under the carwith it on stands, doing the nuts from the back with my arm just fitting through the chasis parts and a mate at the front doing the bolts with the intakes removed. Got the bottom one out, and tilted the alternator to get at the top one. I must have fat arms.
