My 2015 Mitsubishi Mirage had a strange little incident the other day. I have posted this on the forum for these cars and as far as the people on that site know, I am the first to experience this exact issue. I also called the Mitsubishi dealer and they said this would be under warranty if it happened again. They said they had never experienced an issue like this in the Mirage either. Whatever this is isn’t a common problem which is good and bad.
I was pulling out into traffic and then there was a sudden momentary loss of power and then power returned. The check engine and traction control light were on. I pulled into another parking lot and when I came out, the check engine light was on but the traction light was off. I put the car in reverse to backup and it stalled. There was an Autozone across the street so I took it over there and had the code read. The P0068 appears to be a mismatch in input from the MAF, MAP, or TPS sensors.
I was low on gas but not that low so I went across the street to a gas station. While the car was filling up opened the hood and unplugged/replugged any wiring connectors going to sensors around the intake and manifold, wondering if it was a bad connection. The car took about 7.5 gallon of gas. These hold like 9.2 gallons or something.
I got in and started the car and there was no more check engine light. I hadn’t cleared the code so that wasn’t why. Anyway, I have been driving the car like normal the past 3 days with no repeats of the behavior.
I figure that a connector might have been loose from the factory or after the repairs from when I hit a deer a few months back. The car sustained front end and side damage so maybe something wasn’t plugged in snug enough after the work.
I guess I could have had a bad tank of gas and was starting to suck moisture or something. I would have thought that would have triggered a misfire or something so my guess leans to a loose connection. The CEL went away immediately when I started the car. The new tank of gas would have at least taken several seconds to have any impact.
