Nissan Frontier D40 error p0101, does not drive well.
(qr25de) 2016

Once in the morning an error was displayed. I read it, it showed p0101.
Erased, she reappears after 1-2 miles.

In this case, it does not matter whether the error is lit or not, the speed is limited to 70 ml / h. Acceleration to 60ml - over 40 seconds.

What has already been checked:
  • put a new MAF sensor
  • replacement of the air filter
  • checking the MAF sensor wires
  • check the "intake manifold" for leaks, smoke machine.

Results 0

Please help, dear friends!

How many miles? Could be cats, when mine went south it threw same code, replacing MAF did not help, new cats and all is good.If you have less than 80K mileage they should be replaced for free.

they are not even sold in Ukraine. they are simply cut out, and the car is used without them.
in Ukraine, the level of laws remained somewhere in the 19th century))

The primary & secondary cats actually quiet down the raucous VQ40's raspy engine notes quite a bit.

Weld in a couple of cherry bombs as resonators and it'll quiet down quite a bit. Did this to my raspy 1992 Grand Prix STE with 4Cam and 5speed stick and changed the exhaust note quite a bit. Flowmaster 40s are quite raucous on their own, this should help you as well.
