Engine Code 24

[elemgee]

While driving to work today my check engine light came on, and when I checked the code (its a 92 SVX) it was a 24, which I understand is the bypass air control solenoid valve. Can someone tell me where this is and is it something I can replace/fix? is this the same thing as the idle air control valve on the bottom of the throttle body? If so, I removed and cleaned it a couple of months ago, but didnt get the error code until today.

Thanks.

Yes they are the same part.

As in so many cases, you need to think of how the ECU can report the issue. Is a '92 model ECU sophisticated enough to expect an RPM increase and issue a code when it doesn't occur? More than likely not, so the next point would be that the ECU is observing a circuitry problem, in other words it expects to 'see' a specific voltage range and it isn't. My point is, before throwing a new part on be sure to investigate the surrounding wiring, connector, etc. - it might save you a few bucks. And, in the advent that it is that sophisticated, investigate the connecting hoses, etc. for holes, collapsing, internally pluggged, etc.

This just happened to me today...got the code now and cleaned the valve a week ago. The resistance was fine when I removed the valve.
