p1122 and p1126 codes?

I just changed my timing chain and got a new mass airflow sensor. Now it seems sometimes when i hit the gas it skips or hesitates for a second. So i pulled the codes p1122 and p1126 Does anyone know what this problem could be?

Did you reset the ECU? Sounds like an idle relearn would fix that since its at idle, or so that's what the code tells me.

DTC P1122 ELECTRIC THROTTLE CONTROL FUNCTION

Description

NOTE: If DTC P1122 is displayed with DTC P1121 or 1126, first perform the trouble diagnosis for DTC P1121 or P1126.

Electric Throttle Control Actuator consists of throttle control motor, throttle position sensor, etc. The throttle control motor is operated by the ECM and it opens and closes the throttle valve.

The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feedback to the ECM to control the throttle control motor to make the throttle valve opening angle properly in response to driving condition.

On Board Diagnosis Logic






Fail-Safe Mode






DTC Confirmation Procedure

NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.

WITH CONSULT-II


Turn ignition switch "ON" and wait at least 2 seconds .







Select "DATA MONITOR" mode with CONSULT-II.
Start engine and let it idle for 5 seconds .
If DTC is detected, go to "Diagnostic Procedure".
WITH GST
Follow the procedure "WITH CONSULT-II" above.

Diagnostic Procedure

Component Inspection






THROTTLE CONTROL MOTOR RELAY


Apply 12V direct current between relay terminals 1 and 2.







Check continuity between relay terminals 3 and 5.
If NG, replace throttle control motor relay.
THROTTLE CONTROL MOTOR


Disconnect electric throttle control actuator harness connector.







Check resistance between terminals 3 and 6. Resistance: Approximately 1 - 15 Ohm [at 25 °C (77 °F) ]
If NG, replace electric throttle control actuator and go to next step.
Perform "Throttle Valve Closed Position Learning".
Perform "Idle Air Volume Learning".
Remove and Installation

ELECTRIC THROTTLE CONTROL ACTUATOR
Refer to "INTAKE MANIFOLD".

DTC P1126 THROTTLE CONTROL MOTOR RELAY

Component Description
Power supply for the Throttle Control motor is provided to the ECM via throttle control motor relay. The throttle control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends an ON signal to throttle control motor relay and battery voltage is provided to the ECM. When the ignition switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not provided to the ECM.

Consult-II Reference Value In Data Monitor Mode






On Board Diagnosis Logic











FAIL-SAFE MODE
When the DTC P1124 is detected in the two consecutive trips, the ECM enters fail-safe mode and the MIL lights up.

When the DTC P1126 is detected even in the 1st trip, the ECM enters fail-safe mode and the MIL lights up.

DTC Confirmation Procedure

NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.

PROCEDURE FOR DTC P1126

With CONSULT-II


Turn ignition switch "ON" and wait at least 2 seconds .







Select "DATA MONITOR" mode with CONSULT-II.
Start engine and let it idle for 5 seconds .
If DTC is detected, go to "Diagnostic Procedure".
With GST
Follow the procedure "With CONSULT-II" above.

for me, if this code went hard like im seeing through your diagnosis, the TB for our some models are known to get bad and cause these kind of codes because of lack of maintenance for the TB its better just to replace the TB and toggle the ignition 10x and do a proper IDLe volume relearn using consult 2

although you still replaced the TB i suggest bring it to a nissan dealer and ask them if they can air relearn if doesnt relearn, your ECM could be ****ed up im only saying this because ive replace alot TB before but i didnt realized that ECM could be malfunctioning as well. try do pin checks on teminal 55 and 32 see it has continuity
