P0222

DTC P0222 TP SENSOR




Component Description
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 the 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 Confirmation Procedure

NOTE: If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.

TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.

WITH CONSULT-II
1. Turn ignition switch ON.




2. Select "DATA MONITOR" mode with CONSULT-II.
3. Start engine and let it idle for 1 second.
4. If DTC is detected, go to "Diagnostic Procedure" below.

WITH GST
Follow the procedure "WITH CONSULT-II" above.

THROTTLE POSITION SENSOR
1. Reconnect all harness connectors disconnected.
2. Perform EC-89, "Throttle Valve Closed Position Learning". Throttle Valve Closed Position Learning
3. Turn ignition switch ON.
4. Set selector lever to D position (A/T), 1st position (M/T).




5. Check voltage between ECM terminals 50 (TP sensor 1 signal), 69 (TP sensor 2 signal) and ground under the given conditions.
6. If NG, replace electric throttle control actuator and go to the next step.
