(41) Accelerator Position Sensor 1 Abnormality (DTC P2122 / 91-4, P2123 /
91-3)
P2122 / 91-4: Accelerator position sensor 1: Low
Behaviour during malfunction:
• Insufficient output
Detection item:
• Sensor / wiring harness open circuit, ground short
DTC set preconditions:
• Battery voltage is normal
• Sensor supply voltage VCC2 is normal
DTC set parameter:
• Accelerator position sensor voltage 1 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
