DTC P0488 Exhaust Gas Recirculation Throttle Position Control Range / Performance
DTC P213B Exhaust Gas Recirculation Throttle Position Control (Range / Performance)
DESCRIPTION
The ECM opens and closes the throttle valve using a rotary solenoid type actuator. Due to the opening and closing of the valve, the exhaust gas recirculation volume can be properly controlled. Also, engine vibration and noise will be reduced by closing the valve when the engine is stopped.
| DTC Detection Drive Pattern | DTC Detection Condition | Trouble Area |
| Over a period of 10 seconds or more, slowly raise engine speed to 3000 rpm and lower it | The throttle motor activation duty is less than 10% or 90% or more for 30 seconds (1 trip detection logic).
| Throttle valve (for Bank 1) stuck Throttle valve (for Bank 1) does not move smoothly Open or short in throttle control motor (for Bank 1) circuit ECM |

| Condition | Throttle Valve Position |
| Moment when accelerator pedal is depressed further or released at 3000 rpm | Throttle valve opening angle varies smoothly |
MONITOR DESCRIPTION
The ECM opens and closes the throttle valve by adjusting the current flowing to the rotary solenoid with a duty ratio. If the throttle valve does not move smoothly or is stuck, the duty ratio used during valve movement control increases or decreases greatly. The ECM will determine that the throttle valve is malfunctioning and illuminate the MIL.

INSPECTION PROCEDURE
- NOTICE:
- After replacing the ECM, the new ECM needs registration () and initialization ().
- HINT:
| 1.CHECK HARNESS AND CONNECTOR (THROTTLE CONTROL MOTOR POWER SOURCE) |
Disconnect the throttle control motor connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
for Bank 1 Tester Connection Switch Condition Specified Condition C85-2 (VCR) - Body ground Ignition switch ON 11 to 14 V for Bank 2 Tester Connection Switch Condition Specified Condition C86-2 (VCR) - Body ground Ignition switch ON 11 to 14 V
|
| ||||
| OK | |
| 2.CHECK HARNESS AND CONNECTOR (GROUND CIRCUIT) |
Disconnect the throttle control motor connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance (Check for Open):
for Bank 1 Tester Connection Condition Specified Condition C85-3 (E2R) - Body ground Always Below 1 Ω for Bank 2 Tester Connection Condition Specified Condition C86-3 (E2R) - Body ground Always Below 1 Ω
|
| ||||
| OK | |
| 3.CHECK HARNESS AND CONNECTOR (THROTTLE CONTROL MOTOR - ECM) |
Disconnect the throttle control motor connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance (Check for Open):
for Bank 1 (LHD) Tester Connection Condition Specified Condition C85-1 (VTAR) - C45-42 (LUSL) Always Below 1 Ω for Bank 2 (LHD) Tester Connection Condition Specified Condition C86-1 (VTAR) - C45-84 (LUS2) Always Below 1 Ω for Bank 1 (RHD) Tester Connection Condition Specified Condition C85-1 (VTAR) - C46-42 (LUSL) Always Below 1 Ω for Bank 2 (RHD) Tester Connection Condition Specified Condition C86-1 (VTAR) - C46-84 (LUS2) Always Below 1 Ω
- Standard Resistance (Check for Short):
for Bank 1 (LHD) Tester Connection Condition Specified Condition C85-1 (VTAR) or C45-42 (LUSL) - Body ground Always 10 kΩ or higher for Bank 2 (LHD) Tester Connection Condition Specified Condition C86-1 (VTAR) or C45-84 (LUS2) - Body ground Always 10 kΩ or higher for Bank 1 (RHD) Tester Connection Condition Specified Condition C85-1 (VTAR) or C46-42 (LUSL) - Body ground Always 10 kΩ or higher for Bank 2 (RHD) Tester Connection Condition Specified Condition C86-1 (VTAR) or C46-84 (LUS2) - Body ground Always 10 kΩ or higher

| OK | |
| 4.REPLACE DIESEL THROTTLE BODY ASSEMBLY (for Bank 1 or Bank 2) |
Replace the diesel throttle body assembly (for Bank 1 or Bank 2) ().
| NEXT | |
| 5.CHECK WHETHER DTC OUTPUT RECURS |
Clear DTCs ().
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON and turn the tester on.
Start the engine.
Over a period of 10 seconds or more, slowly raise the engine speed to 3000 rpm and lower it.
Enter the following menus: Powertrain / Engine / DTC.
Read the DTCs.
| Result | Proceed to |
| P0488 and/or P213B is output | A |
| No DTC is output | B |
|
| ||||
| A | |
| 6.REPLACE ECM |
Replace the ECM ().
|
| ||||
| 7.REPAIR OR REPLACE HARNESS OR CONNECTOR (THROTTLE CONTROL MOTOR - BATTERY) |
|
| ||||
| 8.REPAIR OR REPLACE HARNESS OR CONNECTOR |
| NEXT | |
| 9.CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED |
Connect the intelligent tester to the DLC3.
Clear the DTCs ().
Turn the ignition switch off.
Start the engine.
Over a period of 10 seconds or more, slowly raise the engine speed to 3000 rpm and lower it.
Confirm that the DTC is not output again.
- HINT:
- Perform the following procedure using the tester to determine whether or not the DTC judgment has been carried out.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input DTC P0488 and/or P213B.
Check that STATUS is NORMAL. If STATUS is INCOMPLETE or UNKNOWN, over a period of 10 seconds or more, slowly raise the engine speed to 3000 rpm again and then idle the engine for 5 minutes.
