DTC P2101: Notes

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

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.
