Submitted: 7 years ago.
Category: Dodge
Expert:  brownjeff replied 7 years ago.

Is this the only code?

 

What engine is in the Ram?

Customer: replied 7 years ago.
code po300, code po339, 5.7 hemi
Expert:  brownjeff replied 7 years ago.

The plugs are a little worn as the gap should be 45 thou.

 

The code is for a crank sensor not a speed sensor. The crank sensor controls timing and can cause the other code of a misfire.

 

I suggest replacing the crank sensor.
