Increase Resistance on Air Exhaust Solenoid Circuit - YKon

[1stchiefsfan]

I am working on air ride system on my Yukon. the computer trouble code says the air exhaust solenoid is bad. I bench tested it and it works fine. I think the problem is the resistance. the resistance is suppost to be between 18 and 45 ohms. it reads right on 18. I think the computer is reading that as bad. what can I do to increase the resistance on this solenoid circuit??

Any input will be appreciated.

Welcome to PF;
You can increase the DC resistance by adding a resistor in series.
For such a low resistance - a length of wire may do the trick.

It may be that the solenoid is on the way out with internally shorted turns.
Add a couple of ohms resistance. If that fixes the fault detection then replace the solenoid with a good one.
Deviation from a manufacturers standard circuit does not usually engender reliability.
