SOURCE: 05 Gnd Caravan 3.3L - code: P0406

Exhaust gas recirculation sensor A (circuit high)
Obviously the sensor or connection is faulty. I'd try cleaning connection with contact cleaner, add some di-electric grease/lube to the connection, check all vacuum lines if applicable & have code erased, and try it.

SOURCE: 2005 Jeep Wrangler Unlimited cruise control will not engage.

check the vacuum line on the right side of the engine. There should be an elbow connector connecting the line to the engine. Does interior fan only come out of the defroster vents by chance?

SOURCE: 2011 Jeep Wrangler JK. ABS

The light is triggered i just 3 occasions: the control unit has lost the connection to one of the wheels sensors, the regulator solenoids have malfunctioned or the pressure in the ABS system is abnormal.
Since you haven't touched the internal elements of the system the only thing left is a fault in one of the wheel sensors - they were damaged or dislodged from their fittings or disconnected when the new suspension system was installed.
Have the sensors checked thoroughly.

REMOVING STOCK SHIFTER FOR 4X4 ON 07 WRANGLER


The 4WD shifter knob on the 2007 JK's is ridiculously hard to remove. Pull straight-up with all your might, then after that fails, get some towels, and a chunk of would with a long pry bar. Hopefully you won't crack your center console.

I am getting two codes from my 05 equinox it's


    P0404
    EGR Sensor Circuit Range/Performance, Stuck Open, to fix, either clean out or replace it, this should do it. p1404 relates to same problem. replace EGR and you should be ok. dont forget to clear the code when repaired.
