Code No. P2135: Throttle Position Sensor (Main and Sub) Range/Performance Problem
OPERATION
- Refer to Code No. P0122: Throttle Position Sensor (main)
Circuit Low Input .
- Refer to Code No. P0222: Throttle Position Sensor (sub) Circuit Low Input .
FUNCTION
- Engine-ECU checks the throttle position sensor output
signal characteristics for abnormal conditions.
TROUBLE JUDGMENT
Check Conditions
- Ignition switch is "ON" position.
- Throttle position sensor (main) output voltage is more than 0.2 V and is less than
4.8 V.
- Throttle position sensor (sub) output voltage is more than 0.2 V and is less than
4.8 V.
- The sum of the output voltage of the throttle position sensors (main and sub) is
less than 4.5 V, or more than 5.5 V.
- Throttle position sensor (main) output voltage is more than 0.2 V and is less than
4.8 V.
- Throttle position sensor (sub) output voltage is more than 0.2 V and is less than
4.8 V.
- Ignition switch is "ON" position.
- Throttle position sensor (main and sub) output voltage is less than the target throttle
position sensor (main) voltage by 0.9 V or less.
- Voltage obtained with the formula given below is more than 0.3 V: (throttle position
sensor (main) voltage - throttle position sensor (sub) voltage)
note | The throttle position sensor voltage used for the judgment is converted into the throttle
position sensor voltage for the internal processing by the engine-ECU. |
PROBABLE CAUSES
- Failed throttle position sensor
- Short circuit in throttle position sensor circuit or loose connector contact
DIAGNOSIS PROCEDURE |
STEP 1. Connector check: B-29 engine-ECU connector and B-20 electronic-controlled throttle valve connector |
Q.
Are the check results normal?
|
Go to Step 2 . |
|
Repair or replace the connector. |
|
STEP 2. Check harness between B-20 (terminal No. 4) electronic-controlled throttle valve connector and B-29 (terminal No. 10) engine-ECU connector. |
|
Q.
Is the check result normal?
|
Go to Step 3 . |
|
Repair the damaged harness wire. |
|
STEP 3. Check harness between B-20 (terminal No. 6) electronic-controlled throttle valve connector and B-29 (terminal No. 11) engine-ECU connector. |
|
Q.
Is the check result normal?
|
Go to Step 4 . |
|
Repair the damaged harness wire. |
|
STEP 4. Replace throttle body assembly. |
|
Q.
Does trouble system persist?
|
Replace the engine-ECU. |
|
Check end. |
