when driving on the expressway - my car will not excelerate past 50 or 60 mpr and the speed limit is 70 - I have to pull over shut the car off wait about 5 or 10 minutes then crank it up and go (not happy at all
my car starts and runs fine in the highway or around town but sometimes i can press the gas pedal all the way down and it would only want to go 20mph. so i shut the car off turn it on and i would work just fine. i had a code come up of p2138. some one please help
throttle body / accelerator pedal sensor replaced throttlr body 4 times and replaced accelerator pedal sensor 2 times still not fixed really mad about it
Check Engine light came on. Three days later the car would not excellerate but stayed at idle. Re-started engine and was able to dive it to the dealership. Was told it needed a new thrttle body according the Nissan. I never had such an issue with any other other cars.
loss of power, check engine light soon came on, felt hesitant
driving at approx. 45 miles per hour engine shut down at once engine light came on. had trouble starting it again and drove slow home didn't have any power when pushing gas pedal.
This problem has occured on 3 or 4 occasions. When idling at a stop sign or red light, there was complete loss of power and subsequently service engine light soon came on. Regained control after turning off the engine, but the scary part is it behaves as if all controls are frozen and the car rolls down on a slope without any control.
Light came on. I figured it may go off, like it was a gas cap issue. Took it to the nissan dealer paid $121.00 and they said they couldnt find anything wrong. But the code was coming up P2101 throttle body actuator. They reset the computer and cut the light off. Told me if it comes on again i would have to have the throttle body replaced. $1042 was the out the door quote. Havent gotten it fixed as of yet. Waitting to scrape up the $1000.
Driving then no acceleration gas pedal press on gas engine revs not moving replaced w new throdle housing runs great
i loose power when i press on gas pedal
right after getting gas, throttle went bad. actually at the pump!
at first I had trouble with the push to start. I would push the button and the dash light lit up the engine clicked and nothing. I Called the dealer he said to change the batteries on the keyless entry which I did. The engine fired up after a few tries but not without a noticeable "lag" to get started. The lag continues 3 days later and the check engine light comes on. I get the code P2101 Failure of throttle body (etc) actuator. I bought the car in 2013 and have had no issues it ran great and 80% of the mileage is highway.
Car began to act like it wanted to stall when idle and felt a bit if hesitation during driving. Service Engine light came on after about a week. Just took to shop and was told throttle body needs replaced.
throttle body
Throttle body intermittently failed near new. During highway driving, engine would remain running, but at idle. Throttle had no effect. Was replaced under warranty, no furhter issue.
throttle body unit went out while driving. Car would only drive at idle speed.
I have not have diagnosis yet, but this too sound like the same problem I am experience. I will be getting a diagnosis to prevent this from happening again.
Check engine light came on I took it to Nissan and they said the had to re set the software for MAF sensor ($130.00 for diagnosis). Light stayed off for about 4 months.service engine light came back on so I took it back and they replaced the MAF sensor and the light stayed off for 3 days. Took it back and is currently still there and they just called and said the throttle body needs to be replaced $1500.00. I told him I'm not paying that because its still under warranty and we purchased the wrap package as well. Waiting for a call back. At least they gave me a rental car at no charge while they figure it out.
Went over a speed bump, check engine light came on, and I lost the power to accelerate. I was able to make it home, with the throttle working and not working seemingly irregardless of the situation. Works on and off as it pleases. Took it to autozone to have them see what error codes came up, and it was P2135/2138- replace throttle body assembly.
Had throttle body replaced at local shop only to have it happen again. Dealership charging 1100 for replacement. Not happy with Nissan about this.
