Angry Yamaha R6 2008 - error code 20

Hi,

I have an R6 08 witch sometimes show error code 20.
If i drive it 5 minuttes and the turn the engine off - and the on - the error is gone ?!

In the 5 minuttes it drives like sh.t.....

Error code 20: the atmospheric pressure sensor voltage and intake air pressure sensor voltage differ greatly.

I have had it to my Yamaha dealer where they have replaced the 2 sensors and the ignition box but i still get the error.

Almost all non original equipment has been taken off: KN-filter, Power-Commander, Xenon and so on.

The only thing left is my full akrapovic system and the rizoma indicators.

Anyone with an idea what to do next ?

Best regards

Re: Yamaha R6 2008 - error code 20

could be a number of things, from the repair manual:

1 -

• Check the couplers for any pins that may be pulled out.
• Check the locking condition of the couplers.
• If there is a malfunction, repair it and connect the coupler securely

2 -

• Repair or replace if there is an open or short circuit.
• Between intake air pressure sensor coupler and ECU coupler.
(black/blue–black/blue)
(pink/white–pink/white)
(blue–blue)

3 -

• Execute the diagnostic mode. (Code No.)
• Replace if defective. Refer to “CHECKING THE INTAKE AIR PRESSURE SENSOR” on page 8-100.


1 -

• Check the intake air pressure sensor hose condition.
• Repair or replace the sensor hose.

2 -

• Replace if defective. Refer to “CHECKING THE ATMOSPHERIC PRESSURE SENSOR” on page 8-99.

from doing some google searching, it seems that this problem has had varying fixes, some just had a pinched or worn wire

Re: Yamaha R6 2008 - error code 20

well if its under warranty then the dealer has to prove it those parts that are causing the code. A lot of people have the full akra exhaust that doesnt cause a code 20, and your rizomas wouldnt have a thing to do with it so i would leave it on and tell the dealership to honor their warranty
