Hello， Any boss ,here i have a quesition , i have P2122 DTC in a 2011 G37COUPE , any body know how to solve that ?

Some body says have to replace the accerlater pedal . but some are not .

any body have been got that P2122 ?



OTHERS , if i arrange to replace the accerlate pedal , i need to make the

release position leaning ? how to do that ? and if i do not make that , what else problem will occur ?


HELP PPP

 

Need more information. Are you fixing a flooded or salvaged car? I would start with the gas pedal harness. Check if there is any damage or corrosion. Then I would replace the pedal. The gas learning is easy. You turn on the ignition and wait 5 secs and then turn off the car.

 

I have found the service manual , but i have a question .


P2127, P2128 APP SENSOR
Description INFOID:0000000006454043
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelerator
position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometer which transform the accelerator pedal
position into output voltage, and emit the voltage signal to the ECM.
The ECM judges the current opening angle of the accelerator pedal
from these signals and controls the throttle control motor based on
these signals.
Idle position of the accelerator pedal is determined by the ECM
receiving the signal from the accelerator pedal position sensor. The
ECM uses this signal for engine operations such as fuel cut.

DTC DETECTION LOGIC


Possible cause:
• Harness or connectors
(APP sensor 2 circuit is open or shorted.)
[CKP sensor (POS) circuit is shorted.]
(EVAP control system pressure sensor
circuit is shorted.)
(Refrigerant pressure sensor circuit is
shorted.)
• Accelerator pedal position sensor (APP
sensor 2)
(Brake booster pressure sensor circuit is
shorted)
• Crankshaft position sensor (POS)
• EVAP control system pressure sensor
• Refrigerant pressure sensor
• Brake booster pressure sensor


i do not know why that have something with the evap control system ? Refrigerant pressure sensor , brake booster pressure ?

why i have check that there is no wire between the app sensor and that sensor above .

anybody can give me the ECM data ? or others about this ?

 

huhu , any technical can tell me ??
