STEP

INSPECTION

ACTION

DTC P2119

Throttle actuator control throttle body range/performance problem

DETECTION 

CONDITION

• The PCM compares the TP with the default TP when the ignition switch is off. If the TP is higher than the 

default TP, the PCM determines that there is a throttle actuator control throttle body range/performance 
problem.

Diagnostic support note

• This is a continuous monitor (CCM).

• The MIL illuminates if the PCM detects the above malfunctioning condition in the first drive cycles.

• FREEZE FRAME DATA is available.

• DTCs are stored in the PCM memory.

POSSIBLE 

CAUSE

• Throttle actuator malfunction

• Throttle valve malfunction

• PCM malfunction

STEP

INSPECTION

ACTION

DTC P2122

Accelerator pedal position (APP) sensor No.1 circuit low input

DETECTION 

CONDITION

• The PCM monitors the APS No.1 signal. If the PCM detects that the APP sensor No.1 voltage is below 0.2 

V, the PCM determines that the APP sensor No.1 circuit has a malfunction.

Diagnostic support note

• This is a continuous monitor (CCM).

• MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.

• FREEZE FRAME DATA is available.

• DTCs are stored in the PCM memory.

POSSIBLE 

CAUSE

• APP sensor malfunction

• Connector or terminal malfunction

• Open circuit between APP sensor terminal F and PCM terminal 1Y

• Short to ground circuit between APP sensor terminal F and PCM terminal 1Y

• Open circuit between APP sensor terminal D and PCM terminal 1Q

• Short to ground between APP sensor terminal D and PCM terminal 1Q
