DTC P2101 DETECTION CONDITION AND POSSIBLE CAUSES

DTC P2101 Throttle actuator circuit range/performance
DETECTION CONDITION  California emission regulation applicable ATX model 
  • The PCM monitors the input voltage from the drive-by-wire relay when the PCM turns the drive-by-wire relay on. If the input voltage is less than 5.0 V,  the PCM determines that the drive-by-wire relay control circuit voltage is low.
  • The PCM monitors the input voltage from the drive-by-wire relay when the PCM turns the drive-by-wire relay off. If the input voltage is more than 5.0 V,  the PCM determines that the drive-by-wire relay control circuit voltage is high.

Diagnostic support note 
  • This is a continuous monitor. (CCM)
  • The MIL illuminates if the PCM detects the above malfunction conditions during first drive cycle.
  • PENDING CODE is available if the PCM detects the above malfunction condition.
  • FREEZE FRAME DATA is available.
  • The DTC is stored in the PCM memory.
Except for California emission regulation applicable ATX model 
  • If any of the following conditions continue for a specified period of time or more the PCM detects a malfunction in the throttle actuator.
    • The voltage of the motor power supply is 4 V or less  while the motor relay is on
    • There is a system error in the electrical throttle control system of the PCM
    • The temperature of the electrical throttle control system in the PCM is 180 °C {356 °F} 

Diagnostic support note 
  • This is a continuous monitor. (CCM)
  • MIL illuminates if PCM detects the above malfunction condition during first drive cycle.
  • PENDING CODE is available if PCM detects the above malfunction condition.
  • FREEZE FRAME DATA is available.
  • DTC is stored in PCM memory.
POSSIBLE CAUSE 
  • Drive-by-wire relay and related circuit malfunction
  • Main relay and related circuit malfunction
  • Throttle position sensor No. 1 and related circuit malfunction
  • Throttle position sensor No. 2 and related circuit malfunction
  • PCM malfunction

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
