Models: 2008-2009 Chevrolet Colorado, TrailBlazer 2008-2009 GMC Canyon, Envoy 2008-2009 HUMMER H3, H3T 2008-2009 Saab 9-7X All Equipped With Engine RPOs LLR, LLV, LL8 Please Refer to GMVIS Condition Some customers may comment that the malfunction indicator lamp (MIL) is illuminated. Some customers may also comment that the engine runs rough. The technician may find DTCs P0300, P0301, P0302, P0303, P0304, P0305, or P0306 set as current or in history, depending on which engine the vehicle is equipped with. Upon further examination, the technician may observe evidence of water intrusion into the spark plug recess area. Cause This condition may be caused by an engine being exposed to a large quantity of water, which may result in some of the water seeping down past the vented threads of an ignition coil bolt, then flowing through the vent opening that is located in the bottom of the related ignition coil bolt hole, and collecting in the spark plug recess area. Correction Important: DO NOT reprogram or replace the engine control module (ECM) for this condition. If evidence of water intrusion in the spark plug recess area/s is not observed, then refer to the appropriate DTC procedures in SI.

BACKGROUND Over time, the power tailgate support struts can lose internal pressure. If they lose enough pressure, the struts may not keep the tailgate up after you open it. A tailgate that lowers unintentionally could cause an injury. REPAIR PROCEDURE NOTE: • Wear eye protection when you pry on the tailgate support strut clips. • Have an assistant hold up the tailgate during the procedure. 1. Pry up the clip on both ends of the tailgate support struts with a flat-tip screwdriver. Then remove the struts by pulling them out of the upper and lower pivot bolts. 2. With the clip on both ends of the new support struts flush to the strut body, install the new struts by pressing the strut ends into the upper and lower pivot bolts. Make sure both support struts are securely attached to the pivot bolts. 3. Center-punch a completion mark above the 11th character of the engine compartment VIN:

Test Description The numbers below refer to the step numbers on the diagnostic table. 2. Allow the engine to cool before performing this test. If the sensor is at the operating temperature, the HO2S voltage will stay high or low. If the HO2S voltage stays between 300-700 mV this indicates the HO2S heater is inoperative. 3. If more than one HO2S DTC is set, this is a good indication that the HO2S fuse is open. Test all the related circuits going to all the heated oxygen sensors for a short to ground. If you cannot locate a shorted circuit, it may be necessary to disconnect each HO2S one at a time to locate a shorted sensor. 4. This step determines if an ignition positive voltage supply is available at the sensor.
