P2132
P0222, P0223, P2132, P2133 TP SENSOR
Description
Electric throttle control actuator consists of throttle control motor, throttle position (TP) 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 potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
DTC Logic
DTC DETECTION LOGIC
NOTE:
If DTC P0222, P0223, P2132 or P2133 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. Refer to P0643.
DTC Detection Logic:
DTC CONFIRMATION PROCEDURE

1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.
- GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and let it idle for 1 second.
2. Check DTC.
Is DTC detected?
YES - Go to P0222.
NO - INSPECTION END
Diagnosis Procedure

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 harness connector 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
Refer to P0222.
Is the inspection result normal?
YES - GO TO 7.
NO - GO TO 6.
