2004 peterbilt 379 c-15 flash code from self diagnostic test on cruise control

I will look in book tommorow light is on or no

 

What are you doing when the light comes on?????

 

it means you,ve got an open or shorted diagnostic light circuit

 

I have a code on my pete just wondering what it is its getting worked on right no 287-5 is the code if anyone knows thanks

 

i have 387 2004 pete codes 93 94 95 variable valve actuators replace 2 and still the problem

 

Code 95 is intake valve actuation pressure sensor and is located on passenger side front of engine by the t-stat housing. You could try replacing that sensor to get rid of code 95. Good luck.

 

I will try it thanks
