Any nissan techs here. - 11/25/17 07:13 PM
truck did something very strange a few days ago. I was waiting in traffic at a full stop with foot on the brake. the engine suddenly surged to full throttle, and the rear tires broke loose and started squealing, I pulled the e brake as hard as I could and put it in park, then shut the engine off. I know these trucks (o5 frontier ) use the electronic driver by wire throttle system. The gas pedal is basically a potentiometer or pedal position sensor, that is linked with the ECU, that tells the throttle body motor to open or close. I cleaned my throttle body good, it was quite gummed up, and it improved my idle. I am worried that the unintended throttle surge will happen again, while my wife is driving. I put a obd 2 code scanner and it gave 2 02 sensor codes and one evap system code, but nothing to do with the throttle or fuel system. The toyotas had a problem of the same nature a few years back and they hired NASA scientist to try and figure it out, but they couldnt. finally they shimmed a portion of the lever part on the throttle apparature, and that supposedly fixed it.
In my case, it could not have been a sticking of the throttle,
because I was at a full stop . NO MY OTHER FOOT WAS NOT ON THE THROTTLE, IVE BEEN DRIVING OVER 30 YEARS.
There are supposed to be redundant systems built into the pedals and computer, that keep this from happening. I did some testing and the frontier will shut off at the key in drive so if it happens again, at least I know I can shut it off. I called Nissan usa and they were no help at all, but I got the complaint documented at least. what i want to know is if a dirty throttle body can cause this situation, and what should be done to correct it. If I take it to the dealer, they wont find any codes, drive it around the block, charge me 500.00 and tell me its fine. Truck has 122.000 miles, and has been a great truck, except for all of the airbag problems.
I have done research on the internet and this same situation has happened to several other nissan owners. not alot like Toyota, but =enough to cause concern. Nissan did a recall on foot pedals in japan for another issue, UI think it was failure to accelerate , or stalling issues. None in the US though. I think my next move may be to go to nissan, and buy an OEM gas pedal and put it on . unless I get a better reccommendation
