Description

INFOID:0000000009719995

Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement. 
The throttle position sensor has two sensors. These sensors are a
kind of potentiometer which transform the throttle valve position into
output voltage, and emit the voltage signals to the ECM. The ECM
judges the current opening angle of the throttle valve from these sig-
nals and controls the throttle valve opening angle in response to
driving conditions via the throttle control motor.

DTC DETECTION LOGIC

NOTE:
If DTC P0222 or P0223 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
Refer to 

EC-352, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

DTC No.

Trouble diagnosis name

DTC detecting condition

Possible cause

P0222

Throttle position sensor 
1 circuit low input

An excessively low voltage from the TP sensor 
1 is sent to ECM.

• Harness or connectors

(TP sensor 1 circuit is open or shorted.)

• Electric throttle control actuator

(TP sensor 1)

P0223

Throttle position sensor 
1 circuit high input

An excessively high voltage from the TP sensor 
1 is sent to ECM.

3.

CHECK THROTTLE POSITION SENSOR 1 GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Check the continuity between electric throttle control actuator and ECM harness connector.

4.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair open circuit, short to ground or short to power in harness or connectors.

4.

CHECK THROTTLE POSITION SENSOR 1 INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT

1.

Check the continuity between electric throttle control actuator and ECM harness connector.

2.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair open circuit, short to ground or short to power in harness or connectors.

5.

CHECK THROTTLE POSITION SENSOR
