DTC P2100:00 [L8, LF, L5]

id010242851000

DTC P2100:00

Throttle actuator circuit open
DETECTION CONDITION
•  The PCM monitors the electronic throttle valve actuator current. If the PCM detects the electronic throttle valve actuator current is below the threshold current, the PCM determines that the electronic throttle valve actuator circuit has a malfunction.
Diagnostic support note
•  This is a continuous monitor (CCM).
•  MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA is available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Throttle valve actuator malfunction
•  Open circuit in wiring harness between throttle body terminal F and PCM terminal 2BE
•  Open circuit in wiring harness between throttle body terminal E and PCM terminal 2BF
•  Connector or terminal malfunction
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED
•  Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service information.
If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
CLASSIFY INTERMITTENT CONCERN OR CONTINUOUS CONCERN
•  Clear the DTC using the M-MDS.
•  Start the engine and idle it.
•  Is the PENDING CODE for this DTC present?
Yes
Go to the next step.
No
Go to INTERMITTENT CONCERNS TROUBLESHOOTING procedure.
(See INTERMITTENT CONCERN TROUBLESHOOTING [L8, LF, L5].)
4
INSPECT POOR CONNECTION OF THROTTLE BODY CONNECTOR
•  Switch the ignition to off.
•  Disconnect the throttle body connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunctions?
Yes
Repair or replace the terminal and/or connector, then go to Step 11.
No
Go to the next step.
5
INSPECT THROTTLE VALVE ACTUATOR
•  Inspect the throttle body.
•  Is the throttle body normal?
Yes
Go to the next step.
No
Replace the throttle body, then go to Step 11.
(See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L5].)
6
CLASSIFY MALFUNCTION ET POWER SUPPLY CIRCUIT OR CONTROL CIRCUIT
•  Switch the ignition to ON (Engine off).
•  Measure voltage between throttle body terminal F (wiring harness-side) and body ground.
•  Is the voltage B+?
Yes
There is a malfunction at the control circuit.
Go to Step 9.
No
There is a malfunction at the power supply.
Go to the next step.
7
INSPECT POOR CONNECTION OF PCM CONNECTOR
•  Switch the ignition to off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunctions?
Yes
Repair or replace the terminal and/or connector, then go to Step 11.
No
Go to the next step.
8
INSPECT POWER CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition to off.
•  Inspect for continuity between throttle body terminal F (wiring harness-side) and PCM terminal 2BE (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for open circuit, then go to Step 11.
9
INSPECT POOR CONNECTION OF PCM CONNECTOR
•  Switch the ignition to off.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the terminal and/or connector, then go to Step 11.
No
Go to the next step.
10
INSPECT CONTROL CIRCUIT MALFUNCTION FOR OPEN CIRCUIT
•  Inspect for continuity between throttle body terminal E (wiring harness-side) and PCM terminal 2BF (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for open circuit, then go to the next step.
11
VERIFY TROUBLESHOOTING OF DTC P2100:00 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Switch the ignition to ON (Engine off).
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine and warm it up completely.
•  Is the same DTC present?
Yes
Replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [L8, LF, L5].)
No
Go to the next step.
12
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Is there any DTC present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [L8, LF, L5].)
No
Troubleshooting completed.
