OBD II Sensor Error Reading
My Question:
How do I remove the check engine light?
My Innotech 3100 OBD II Code Reader gets an error signal every time it reads my Dakota.
Though it works on all other 5 models of vehicles in my household.
This same reader diagnosed my truck 2 years earlier in 2013.
I own a Dodge Dakota SLT 2007 V6 3.5L King Cab.
My check engine light comes on and off throughout its lifetime.
In 2013, I had a reading of p0303. Which indicates a 3rd cylinder misfiring.
I corrected that problem, however, since then the check engine light continues to reappear at times, and disappear for no reason at all, also for equal amounts of time.
Now as I try to pass SMOG this year, my emissions are great from being tested, but the check engine light is causing me not to get my SMOG certificate.

sounds like a partially clogged catalytic converter. When you had the misfire, the cat on the side of the misfire started to clog up and the O2 sensor is most likely dirty as well, causing the intermittent check engine light.
buy the aerosol Seafoam and do the spray treatment from the front of the throttle body. The liquid one that you do using a vacuum line is too much work if you ask me but if you pick the correct line, it's just as good. This should clean up the cat for you, and at the same time, clean the throttle body, intake manifolds, the top of the valves, the cylinder walls, the top of the pistons, the exhaust manifolds and some of the rest of the exhaust.
Made a huge difference for me after my misfire incident i was getting. Even with new plugs and coils, i had a random misfire that kept occurring that was caused by a clogged cat, too much exhaust pressure on the driver's side exhaust causing spent exhaust to be re compressed. after the seafoam, the truck breathed better then when i got it.
