P2135

DTC P2135 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 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.




CONSULT-III Reference Value in Data Monitor Mode




On Board Diagnosis Logic
This self-diagnosis has the one trip detection logic.

NOTE: If DTC P2135 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. Refer to EC-408, "DTC P0643 SENSOR POWER SUPPLY". P0643




FAIL-SAFE MODE

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 8 V at idle.

1. Start engine and let it idle for 1 second.
2. Check DTC.
3. If DTC is detected, go to "Diagnostic Procedure" below.

Diagnostic Procedure

Component Inspection

THROTTLE POSITION SENSOR
1. Reconnect all harness connectors disconnected.
2. Perform EC-78, "Throttle Valve Closed Position Learning". Throttle Valve Closed Position Learning
3. Turn ignition switch ON.
4. Set shift lever to D position (CVT) or 1st position (M/T).




5. Check voltage between ECM terminals 33 (TP sensor 1 signal), 34 (TP sensor 2 signal) and ground under the given conditions.
6. If NG, replace electric throttle control actuator and go to the next step.
7. Perform EC-78, "Throttle Valve Closed Position Learning". Throttle Valve Closed Position Learning
8. Perform EC-78, "Idle Air Volume Learning". Programming and Relearning
