Turbocharger Engine Overboost

Possible Causes:



The boost pressure sensor signal circuit is pulled high in the ECM. At ignition ON, a normal voltage measurement of the signal circuit with a DMM is 5.60 volts.
 
The CAC is connected to the turbocharger and to the throttle body by flexible duct work that requires the use of special high torque fastening clamps. These clamps cannot be substituted. In order to prevent any type of air leak when servicing the ductwork, the tightening specifications and proper positioning of the clamps is critical, and must be strictly adhered to.
 
Use a solution of dish soap and water in a spray bottle to pinpoint any air leaks.
