I have 2009 Nissan Versa, and I had the Crank ANgle Position sensor and Crank Sensor Connector replaced. I picked the car up on Monday, and today when driving on the freeway, I noticed the same problem: The car was having a hard time getting over 60mph, and I had to keep my foot on the gas. Then when I would press the gas, I would hear a buzzing sound. When I got off the freeway, and came to a light it felt as though the engine was going to stall as it did last week. What is the most likely problem and solution?
I had the catalytic converter changed for a Magnaflow aftermarket in early January, because of similar issue. The car worked fine up until last week. ...
Scotty doesn't usually return to topics he has already answered. As he said you need to dig into the live data to see what's going on. Also you did not say if OEM sensors were installed. Aftermarket sensors frequently don't work properly.
Well I would have to check it out personally with my scan tool and see what's going on. But if you had to replace both of those sensors, sometimes it's not the sensor. But the fact that the timing chain is worn and that's an expensive job. The computer would get bad data. Blame the sensors when it's that chiming chain as stretched
@scottykilmer Ok, thank you
@scottykilmer I had the catalytic converter changed for a Magnaflow aftermarket in early January, because of similar issue. The car worked fine up until last week. When they replaced the converter, the mechanic took off the old one (also aftermarket), and drove it without it attached to see if it was some other issue. The mechanic did not have the same problem with the catalytic off of the vehicle.
