So my CEL comes on today when I was driving home. I figured I would check the code and see what was wrong. The only problem is that it didnt give me a code like I have seen before. The light just flashed 3 short times, over and over again. I was under the impression that the code should be a 2 digit number, short flashes for the first digit and long for the second. Am I wrong? What does this mean?

 

The short flashes is the first number, the second phase of quicker numbers is the last number.

 

del code 3 is manifold absolute pressure circuit low input or high input.

hope this helps if you need further info let me know
