Code No. P2135: Throttle Position Sensor (Main and Sub) Range/Performance Problem <4A9>

OPERATION

Refer to Code No. P0122: Throttle Position Sensor (main) Circuit Low Input <4A9>.
Refer to Code No. P0222: Throttle Position Sensor (sub) Circuit Low Input <4A9>.

FUNCTION

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

TROUBLE JUDGMENT

Check Condition

Ignition switch is in "ON" position.
Throttle position sensor (main) output voltage is 0.35 - 2.5 V.
Throttle position sensor (sub) output voltage is 2.25 - 4.8 V

Judgement Criterion

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 or engine-A-M/T-ECU.

PROBABLE CAUSES

Failed throttle position sensor
Open/short circuit in throttle position sensor circuit or loose connector contact

DIAGNOSIS PROCEDURE

STEP 1. Connector check: A-08 engine-ECU connector or engine-A-M/T-ECU connector and A-118 electronic-controlled throttle valve connector

Q. Is the check result normal?

Go to Step 2 .

Repair.

STEP 2. Check harness between A-118 (terminal No. 4) electronic-controlled throttle valve connector and A-08 (terminal No. 15) engine-ECU connector or engine-A-M/T-ECU connector.

Check output line for damage.

Q. Is the check result normal?

Go to Step 3 .

Repair.

STEP 3. Check harness between A-118 (terminal No. 6) electronic-controlled throttle valve connector and A-08 (terminal No. 16) engine-ECU connector or engine-A-M/T-ECU connector.

Check output line for damage.

Q. Is the check result normal?

Go to Step 4 .

Repair.

STEP 4. Check harness between A-118 (terminal No. 5) electronic-controlled throttle valve connector and A-08 (terminal No. 31) engine-ECU connector or engine-A-M/T-ECU connector.

Check power supply line for damage.

Q. Is the check result normal?

Go to Step 5 .

Repair.

STEP 5. Check harness between A-118 (terminal No. 3) electronic-controlled throttle valve connector and A-08 (terminal No. 30) engine-ECU connector or engine-A-M/T-ECU connector.

Check earthing line for damage.

Q. Is the check result normal?

Go to Step 6 .

Repair.

STEP 6. Replace throttle body assembly.

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

Q. Does trouble system persist?

	Replace engine-ECU or engine-A-M/T-ECU then perform the variant coding (Refer to GROUP 00 - Precautions Before Service - How to Perform Variant Coding ).

	Check end.
