Electronic Throttle Actuator: Testing and Inspection
Electronic Throttle Control System Inspection
Engine coolant temperature compensation inspection
1. Connect the M-MDS to the DLC-2.
2. Access the following PIDs:
-
ECT
-
IAT
-
RPM
3. Verify that the engine is cold, then start the engine.
4. Verify that the engine speed decreases as the engine warms up.
-
If the engine speed does not decrease or decreases slowly, inspect the following:
-
ECT sensor and related wiring harness (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTIONtL3]). See: Coolant
Temperature Sensor/Switch (For Computer)/Testing and Inspection
-
Electronic throttle body and related wiring harness (See THROTTLE BODY INSPECTIONfL3].)
Load compensation inspection
1. Start the engine and idle it.
2. Connect the M-MDS to the DLC-2.
3. Verify that P0506, P0507, or P0511 is not displayed.
-
If P0506, P0507 or P0511 are displayed, perform DTC inspection. (See DTC TABLE[L3].) See: Testing and Inspection/Diagnostic Trouble
Code Descriptions
4. Access the RPM PID.
NOTE: Excludes temporary idle speed drop just after the loads are turned on.
Engine Speed
5. Verify that the engine speed is within the specification under each load condition.
-
If load condition is not as specified, inspect the following:
-
A/C switch and related wiring harness (See CLIMATE CONTROL UNIT INSPECTION[FULL-AUTO AIR CONDITIONER].) (See
CLIMATE CONTROL UNIT INSPECTION[MANUAL AIR CONDITIONER].)
-
Fan switch and related wiring harness (See CLIMATE CONTROL UNIT INSPECTION[FULL-AUTO AIR CONDITIONER].) (See
CLIMATE CONTROL UNIT INSPECTION[MANUAL AIR CONDITIONER].)
Throttle position (TP) sweep inspection
1. Connect the M-MDS to the DLC-2.
2. Turn the ignition switch to the ON position.
3. Verify that none of the following DTC are displayed:
-
P0122, P0123, P0222, P0223, P0638, P2100, P2101, P2102, P2103, P2107, P2108, P2119, P2122, P2123, P2127, P2128, P2135, P2138
-
If any one DTC is displayed, perform DTC inspection.
4. Access TP_REL PID.
5. Verify that the PID reading is within the CTP value. (See O1 -40-6 PCM INSPECTION[L3]). See: Testing and Inspection/Scan Tool Testing and
Procedures/PCM Inspection
-
If the PID reading is out of range, perform the following:
-
Remove the air duct from the throttle valve body.
-
Verify that the throttle valve opens when the accelerator pedal is depressed.
