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 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

Judgment Criterion

Using the formula given below, the voltage of 0.3 V or higher is obtained for 0.5 second: V* - V** - 2 V
V*: throttle position sensor (main) output voltage
V**: throttle position sensor (sub) output voltage.

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-34 engine-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. 1) electronic-controlled throttle valve connector and A-34 (terminal No. 15) engine-ECU connector.

Check output line for short circuit.

Q. Is the check result normal?

Go to Step 3 .

Repair.

STEP 3. Check harness between A-118 (terminal No. 3) electronic-controlled throttle valve connector and A-34 (terminal No. 16) engine-ECU connector.

Check output line for short circuit.

Q. Is the check result normal?

Go to Step 4 .

Repair.

STEP 4. Replace throttle body assembly.

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

Q. Does trouble system persist?

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

	Check end.
