(42) Accelerator Position Sensor 2 Abnormality (DTC P2127 / 29-4, P2128 /
29-3)
P2127 / 29-4: Accelerator position sensor 2: Low
Behaviour during malfunction:
• Insufficient output
Detection item:
• Ground short circuit / open circuit of sensor / harness
DTC set preconditions:
• Battery voltage is normal
• Sensor supply voltage VCC1 is normal
DTC set parameter:
• Voltage of accelerator position sensor 2 is 0.3 V or less
Engine warning light:
•ON
Limp home action by engine ECU (system action):
• Forced Idle (Accelerator = 0 %)
Recovery from error:
• Diagnostic counter = zero or Key switch turn OFF

DTC set parameter:
• Voltage of accelerator position sensor 2 is 4.8 V or more
Engine warning light:
•ON
Limp home action by engine ECU (system action):
• Forced Idle (Accelerator = 0 %)
Recovery from error:
• Diagnostic counter = zero or Key switch turn OFF
