The air pump is located underhood, underneath the intake manifold near the starter motor. The air pump is the main component of the AIR system for California emission level vehicles only. The purpose of the AIR system is to inject air into the exhaust manifold to quickly increase the temperature of the catalytic converter. The air pump creates the pressure needed to inject air into the exhaust manifold. The air pump is controlled by the PCM through the air pump relay in the underhood fuse block (UHFB). Source
A rubber boot covers the duty cycle EVAP purge solenoid. The solenoid attaches to a bracket mounted to the right engine mount. The top of the solenoid has the word TOP on it. The solenoid will not operate unless it is installed correctly. Instructions
