Hi.
I have a 2013 Mitsubishi Outlander Sport. I bought an OBD-II scanner after getting a check engine light. I replaced my air filter, cat, upstream and downstream sensors, and MAF sensor. I was able to clear all those codes, but now my engine light is back on and I am getting the P016A code. Every once in a while the ASC System Service Required light also comes on and the car just runs sad until I restart it a couple of times. Any advice you can share in determining what the specific cause could be would be so helpful. I'm a teacher, so I need to save money where I can and enjoy working on the car. Love your videos.
Thanks.
It turned out to be the throttle body. $1,600 to replace and have it programmed.
This site ight give you some other things to check https://www.autocodes.com/p016a.html
Given all the things you've checked/replaced, I would suspect a fuel pressure/injector problem
I took it to the dealership. They said it was fine. Turns out, they just erased the code. It started having the same trouble (with the same code) the next day. I notice when I am driving up a steep incline, the ASC System Service Required light comes on and the car gets sluggish again. This happens everyday when I'm leaving work and going up the same incline out of the parking garage. Do you think replacing the ECM would correct this? Thanks.
From what I've been able to find, it looks like the ASC message in Mitsubishis is related to the anti-lock braking and traction control. Does your car have an ASC Off switch like some Mitsubishis? Have you checked the wiring and voltages on these systems? It might be a better choice to take it to a place with a high-level scanner to identify the problem rather than replacing the ECU and body control module, as I have found that problems are more often in sensors than the computers.
