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 <M/T> or engine-A/T-ECU <A/T> checks the throttle position sensor output signal characteristics for abnormal conditions.

TROUBLE JUDGMENT

Check Conditions

Ignition switch is in ON position.
Throttle position sensor (main) output voltage is 0.2 - 4.8 V.
Throttle position sensor (sub) output voltage is 0.2 - 4.8 V

Judgment Criterion

The proposed output voltage added from the output voltage of the (main/sub) throttle position sensor is 4.5 V or lower

or

The proposed output voltage added from the output voltage of the (main/sub) throttle position sensor is 5.5 V or higher

PROBABLE CAUSES

Failed throttle position sensor
Short circuit in throttle position sensor circuit or loose connector contact

DIAGNOSIS PROCEDURE

STEP 1. Connector check: D-246 engine-ECU <M/T> connector or D-217 engine-A/T-ECU <A/T> connector and B-31 electronic-controlled throttle valve connector

Q. Is the check result normal?

	Go to Step 2 .

	Repair or replace the connector.

STEP 2. Check harness between B-31 (terminal No. 1) electronic-controlled throttle valve connector and D-246 (terminal No. 115) engine-ECU <M/T> connector or D-217 (terminal No. 115) engine-A/T-ECU <A/T> connector.

Check output line for short circuit.

Q. Is the check result normal?

	Go to Step 3 .

	Repair the damaged harness wire.

STEP 3. Check harness between B-31 (terminal No. 3) electronic-controlled throttle valve connector and D-246 (terminal No. 113) engine-ECU <M/T> connector or D-217 (terminal No. 113) engine-A/T-ECU <A/T> connector.

Check output line for short circuit.

Q. Is the check result normal?

	Go to Step 4 .

	Repair the damaged harness wire.

STEP 4. Replace throttle body assembly.

After throttle body assembly is replaced, re-check for trouble symptom.

Q. Does trouble system persist?

	Replace the engine-ECU <M/T> or engine-A/T-ECU <A/T>.

	Check end.
