P2151 Dodge -

Question

I just got my car serviced. I drive a 2010 dodge Charger. after I got my car home I checked the engine code and P2151 popped up but my engine light is not on. when I run the test to check the engine code, my engine light blinks 9 times then goes solid. I paid quite a large bill for them to repair P2150 which my engine light came on to notify me. If I get a reading of p2151 without the engine light going on should I be concerned?

Answer 1

This depends on what menu you look up the code, there is a emission store code menu, there is a pending code menu, and on some scan tool there is a history code, If this code is in the Pending code menu , be concern the CK ENG LT may not be on , and the code is not fully matured until or if there is a fault detected and  on the next ignition cycle. the CK ENG LT may come on. If this code is in the history code menu it just that, History.
