The dreaded "Check Engine" light came on yesterday in my wagon. First time for me doing this, i used the Bay 13 procedures for checking codes, i got 1-1-1 for both engine and transmision. I did the procedure to clear any trouble codes out. I also had the ABS procedure, so i checked that and got 213 and 214. I cleared the codes there as well. I go sit on the car, turn on the engine and now I have both the "check engine" and "ABS" lights on. I do the procedure again, using the A1, A2 and A3 sockets, only get 1-1-1, but both lights continue to be on as if there is a problem. One odd thing i noticed in the engine compartment (while key was in the II position) was a buzzing sound coming from the area where the throttle body is located.
Any suggestions??

Thank you Klaus, it is a 241 code "EGR flow too low in system".

Following the Haynes Manual, I took out the relay panel, the electric fan, the starter, I removed the nut from the exhaust tube connection and the two bolts that fix the EGR valve. Everything went as expected (2 - 3 busted knuckles) but i could not separate the EGR valve from the tube in the back. I gave it a shot of WD40, closed the hood and went back in the house to rest.

I hope I did not do all this work in vain, but I will appreciate any feedback and ideas on how to fix the fault code 241.

Thank you

The buzzing sound is the idle air control valve. Normal. The ABS light can also be associated with a bad ignition switch. Try wiggling the key around a bit. If the light flickers then the switch could be bad.

Klaus,

You are the man of the hour! The procedures on Bay 13 only listed the procedures for sockets 1, 2 and 3. I sort of got the impression that I was missing something. Where can I find the other procedures (and what the codes would mean). My only other time around that area was to reset the "service" light a few months ago, but this is the first time I get one of the "trouble" lights on.

Thanks so much for your help.

The more I learn, the more I forget. So why learn?

You didn't check A6???
The ABS light will not turn off until you exceed 17mph which is when the ABS does its system check. If the 213 and 214 come back, then check the wiring and the axle. The axle tends to ger rust build up over time and the toothed area can no longer be read by the sensors. You have to look behind the rotor to see the area. A wire brush works wonders if you wear safety goggles.
