Answer Hi Mitchell,
That code means either that the circuit for the egr valve (exhaust gas recirculation) is not working or that the valve itself is not showing the proper functioning.
I would suspect the latter. The egr valve is located in narrow diameter exhaust pipe that branches off the front exhaust manifold and is routed over the engine toward the rear on the passenger side of the engine compartment. Once you find the valve notice that it has a round vacuum hose-operated top piece. the valve body proper which is connected to the exhaust pipe. and a flange between those two parts inside of which is hidden a rod which is the valve stem. The stem has a circumferential slot into which the tip of a screwdriver can be inserted to move the stem back and forth. You will notice spring-action in one direction which closes the valve.
What generally causes the code is that exhaust fumes make the stem sticky such that it won't close tightly. What you need to do is spray some WD-40 on the stem where enters the valve body so as to free-up the 'action'. Move the stem back and forth after spraying it so that the spring action now closes the valve to a dead stop.
You will find the engine accelerates better and slows down to idle when you come to a stop better.
You can erase the code by disconnecting the battery briefly. Then drive for a while to verify that the 32 code remains gone. A 12 code will show saying that you recently disconnected the battery, so ignore that.
