Check engine light on and fault codes stored. Vehicle running normally. Tests/Procedures: 1. Based upon stored fault codes for secondary air system, there is little or no flow of secondary air into engine. Typical causes for this issue are failed secondary air pumps and/or secondary air check valves. Secondary air pump should operate under normal circumstances when vehicle is first started to perform system test. Pump will normally be heard running when standing in front right corner of vehicle. 2. The secondary air pump is located in the right front of engine compartment. A secondary air pump relay located in the glove box is controlled by the engine control module and sends power to the secondary air pump. 3. Air pump can be disconnected and supplied with power and ground at pump to verify operation is possible. 4. Check valve on front right of cylinder head can be supplied with vacuum and visually checked for opening of valve. 5. Vacuum line from check valve to operating solenoid should also be inspected for cracks or being disconnected. Vacuum line follows right side of cylinder head to back of cylinder head to the secondary air solenoid located under left rear side of intake manifold. 6. The solenoid should allow vacuum flow to the check valve during vacuum pump operation. The solenoid is controlled directly by the engine control module and receives power during key-on-engine-off. Potential Causes: A.I.R. Check Valve Engine Control Module (ECM) Codes — Engine control module fault.

1.Drain coolant from drain plugs on radiator and both sides of cylinder block. 2.Remove drain plug on cylinder block. 3.Remove right side engine mounting, mounting bracket and nuts. 4.Remove drive belts and idler pulley bracket. 5.Remove chain tensioner cover and water pump cover. 6.Pushing timing chain tensioner sleeve, apply a stopper pin so it does not return. Then remove the chain tensioner assembly. 7.Remove the 3 water pump fixing bolts. Secure a gap between water pump gear and timing chain, by turning crankshaft pulley 2O° backwards. 8.Put M8 bolts to two M8-threaded holes out of 3 water pump fixing bolt holes 9.Tighten M8 bolts by turning half turn alternately until they reach timing chain rear case. In order to prevent damages to water pump or timing chain rear case, do not tighten one bolt continuously. Always turn each bolt half turn each time. 10.Lift up water pump and remove it. When lifting up water pump, do not allow water pump gear to hit timing chain. INSPECTION 1.Check for badly rusted or corroded body assembly. 2.Check for rough operation due to excessive end play. INSTALLATION 1.Before installing, remove all traces of liquid gasket from mating surface of water pump cover and chain tensioner cover using a scraper. Also remove traces of liquid gasket from mating surface of front cover. 2.Apply a continuous bead of liquid gasket to mating surface of chain tensioner cover and water pump cover. 3.Return the crankshaft pulley to its original position by turning it 2O° forward. 4.Install timing chain tensioner, then remove the stopper pin After installing the tensioner, race the engine at about 3,000 rpm under no load to purge air from the high-pressure chamber. The engine may produce a rattling noise. This indicates that air still remains in the chamber and is not a matter of concern. 5.Install drain plug on cylinder block. 6.Reinstall any parts removed in reverse order of removal
