Code No. P2135: Throttle Position Sensor (main and sub) Range/Performance Problem

OPERATION

Check code No. P0122: throttle position sensor (main) circuit low input (Refer to ).
Check code No. P0222: throttle position sensor (sub) circuit low input (Refer to ).

FUNCTION

Engine-ECU checks the throttle position sensor output signal characteristics for abnormal conditions.

TROUBLE JUDGEMENT

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.

Judgement Criterion

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.

FAIL-SAFE AND BACKUP FUNCTION

Throttle opening degree position is in default position.
The RMS (Forward) and FCM-LS are prohibited. <Vehicles with FCM-LS>

PROBABLE CAUSES

Failed throttle position sensor
Harness damage in throttle position sensor circuit or loose connector contact
Failed engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. Perform resistance measurement at electronic-controlled throttle valve connector.

Disconnect connector, and measure at harness side.
Resistance between terminal TPSE line and earth.

OK: Continuity (2 Ω or less)

Q. Is the check result normal?

	Go to Step 4.

	Go to Step 2.

STEP 2. Check of damage in TPSE line between electronic-controlled throttle valve connector and engine-ECU connector.

Q. Is the check result normal?

	Go to Step 3.

	Repair the connector(s) or wiring harness.

STEP 3. M.U.T.-III diagnosis code

Reconfirmation of diagnosis code.

Q. Is diagnosis code set?

	Replace the engine-ECU.

	Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).

STEP 4. Check of damage in TPS5 line between electronic-controlled throttle valve connector and engine-ECU connector.

Q. Is the check result normal?

	Go to Step 5.

	Repair the connector(s) or wiring harness.

STEP 5. Check of damage in TPSM line between electronic-controlled throttle valve connector and engine-ECU connector.

Q. Is the check result normal?

	Go to Step 6.

	Repair the connector(s) or wiring harness.

STEP 6. Check of damage in TPSS line between electronic-controlled throttle valve connector and engine-ECU connector.

Q. Is the check result normal?

	Go to Step 7.

	Repair the connector(s) or wiring harness.

STEP 7. Replace throttle body assembly.

After replacing the throttle body assembly, reconfirm whether the diagnosis code is set.

Q. Is the diagnosis code set?

	Replace the engine-ECU.

	Check end.
