I have a 2007 Cat C7 . We get a warning light everytime we stop . So I used the scanner and it says we boost pressure voltage to high . I thought sensor ? The as I was checking I was told wastegate on turbo is sticking . Something I did notice is when I accelerate it takes a little bit to show booste . Then when it does it's showing 43 lbs . Seems kind of extreme ? Then as it gets back to idle it will show zero boost the light will come on . Thanks

Lubricate wastegate linkage with your favorite lube, use regulated shop air to W/G actuator and verify function
