You need to be more specific on the actual code (#) There are many parts that make up that system. First you need to locate the fuse for the pump and see if it is blown. If blown, it's the pump. If not, you need to disconnect the hose that leads to the exhaust manifold (near the pump itself/ with the engine COLD.) At cold start-up (when the pump is suppose to be working), see if the pump is blowing air. It suppose to run for a short time, probably no more than 4 minutes If not, there are a number of components that could be the problem. The vaccuum valve/ solenoid, the air pump/solenoid relay and air shutoff valve. If its blowing air, you might check the check valves near the block on each bank ( if your code specifies a left or right bank. Don't burn yourself on a hot engine and turn it off please!!! ) If your code does specify a particular bank (right or left ), try switching the check valves to see if the code switches to the other bank, provided you have a code scanner handy. GOOD LUCK

Yeah, do what he said... The same thing happened to me, i just changed the fuse and that fixed it for a short while, but the little clicking sound you hear came back. good luck. when you fix it, post back what you did, lol, i need to do it too.
