ECM Codes 12, 32, 33

I just plugged a paperclip into the ALDL bit and got the above codes.

12 is normal if then ignition is on but it is not running.

32 means there is a fault with the EGR. What the hell is that?

33 suggests that I have a low vacuum problem with the MAP. Am going to repace all the hoses.

I am annoyed as I was hoping to get a code 43 which was going to be the answer to my crappy engine performance and knocking at WOT.

Anyone know how long a code remains? The sequence repeated a few times but I have had knock before and thought 43 would be indicated.

Any sugestions appreciated as always.

OK, found out about the EGR.

What part does the stock Ty have? Is this a common failure item? Should I replace it with the 32 code?

Anyone know the part number? (where I can find these would help - I have all the service manuals so should be able to do it - am a little lost is all!)

cheers,

Mark

SeattleSy,

I am not sure what chip is in it. I had the saudi chip then a guy in the UK changed it (allegedly)

It flashes once, then twice, then a pause, 3 times then twice, amnother pause and then 3 times and 3 again.

Each sequence of flashes repeats 3 times. I am going out to the car now to look at the sequence again and to see if I can get the part number off the EGR. P/N/ Blank - why is it never easy?!

It's normal for the codes to flash three times each time displayed.. Might I suggest something before you start swapping parts in/out? Why not unplug the ECM B fuse from the fuse block under the dash/steeringwheel for 15 minutes to clear the error codes from the computer.. then start her up and let her idle, then turn on the air etc.. let the computer relearn everything then take her for a spin to see if the errors come back? because they could have been set awhile ago back with the other owner when they were a problem and could have been possibly fixed just not cleared? just my :2cents:

Also you might want to take a peek at what kind of chip you have because that could be the whole bad performances/knock cause.. or possibly purchase a stock chip so you can get her running right before you start throwing big time money/time at her.

There's a factory stock chip out on ebay right now.. don't know how the seller but I imagine you could find one on here as well if you put up a wanted add for one which is what I would do rather then dealing with ebay.

starting with the codes is good, but you have to know what chip you have. That alone could be the cause of your knock issues.
