Pedal Position Sensor 'D' Circuit High
P2123 Pedal position sensor ‘D’ circuit high
Enable Criteria:
• None
Disable Criteria:
• None
Potential failure modes:
• Signalopencircuit(>4.487V)
• Referencevoltageopencircuit
• Referencevoltageshorttoground
• Sensorfailure
Notes: A maximum throttle opening of 15% may be imposed due to this single code. In the case of multiple
codes, a mechanically sprung 7% opening may be applied.
Pedal Position Sensor 'E' Circuit Low
P2127 Pedal position sensor ‘E’ circuit low
Description
Two potentiometers are built into the throttle pedal unit in order to provide a throttle demand signal to the ECU.
Note that the potentiometers operate on 5 volts.
Enable Criteria:
• None
Disable Criteria:
• None
Potential failure modes:
• Signalshortcircuit(<0.283V)
• Referencevoltageopencircuit
• Referencevoltageshorttoground
• Sensorfailure
Notes: A maximum throttle opening of 15% may be imposed due to this single code. In the case of multiple
codes, a mechanically sprung 7% opening may be applied.
