DTC P2101 Throttle actuator circuit range/performance
• If the PCM detects any of the following conditions, the PCM determines that the throttle circuit has a
malfunction.
— Default throttle angle that the PCM stored and the throttle angle with drive-by-wire-relay off is not
significant.
— Voltage from drive-by-wire-relay is too high or too low
— PCM detects large voltage difference between the drive-by-wire-relay and the main relay
DETECTION
— PCM internal malfunction
CONDITION

Diagnostic procedure
STEP
1 VERIFY FREEZE FRAME DATA HAS BEEN
RECORDED
• Has the FREEZE FRAME DATA been
recorded?
2 VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Bulletins and/or on-
line repair information availability.
• Is any related repair information available?
3 VERIFY RELATED PENDING AND STORED
DTCS

off).
• Verify pending and stored DTCs using the M-
MDS.
• Are any DTCs present?
4 IDENTIFY TRIGGER DTC FOR FREEZE FRAME
DATA
• Is DTC P2101 on FREEZE FRAME DATA?
5 INSPECT PCM CONNECTOR FOR POOR
CONNECTION
• Turn the ignition switch to off.
• Disconnect the PCM connector.
• Inspect for poor connection (such as damaged,
pulled out terminals, corrosion).
• Is there any malfunction?
6 INSPECT MAIN RELAY OUTPUT VOLTAGE
• Turn the ignition switch to off.
• Connect the PCM connector.
• Turn ignition switch to the ON position (Engine
off).
