The IVA housings DO NOT open the intake valves letting exhaust back into the intake. Damaged O-ring seal or missing O-ring seal. If the problem has not been eliminated, proceed to Test Step 2. Proceed to Test Step 8. I has replaced many of these sensors for the code. This allows the temperature of the oil in the rail to warm up. You may need to apply a load to the engine in order to verify that the problem is resolved. 36s - ⦠The ECM commands the control valve to close when the coolant temperature exceeds 20 °C (68 °F). Hey guys, question about the Valve Group Warm-Up Solenoid controler for the IVA on my 2005 C15 MXS. A component has an internal failure. It may be necessary to use a penlight to determine the position of the spool. The spool should be fully closed. Replace the intake valve actuation pressure sensor. The engine oil pressure sensor is located on the block under the intake manifold. The ECM compares oil-pressure data, collected 67 times a second from a. sensor mounted in the cylinder-head gallery, with desired pressure and adjusts cur- rent intensity accordingly. Carefully remove the control valve from the engine. Valve springs (59) raise intake valves (61), rocker arm (58), and piston (57). Look for debris that could cause the check valve to stick. 1. 5/16 JIC Female to 1/4 JIC Male This can be caused by the following conditions: Engine Intake Valve Actuation System Oil Pressure : Not Responding Properly.
