Pedal Position Sensor 'D' Circuit Low
P2122 Pedal position sensor ‘D’ 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:
• Signalshortcircuit(<0.283V)
• Referencevoltageopencircuit
• Referencevoltageshorttoground
• Sensorfailure
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.
