2006 Dodge Ram 1500 hemi 5.7L

Question

Just purchased this from a Dodge dealer and they did an oil change on it. Well it is throwing the p1521 code. More than likely the person that owned it wasn't putting the correct oil in it to begin with. Whatever the case, if the dealer put the correct oil in,5w20, what can I do to get rid of the code to let the computer know that the oil is correct?

Answer 1

P1521 Incorrect engine oil type.

Reprogram the ECM. Dodge has a TSB about this code condition, to resolve the issue you use TSB # 18-008-08A., what this is about is to reprogram the ECM.
