P022015 |
Throttle/Pedal Position Sensor/Switch "B" Circuit Short to Battery or Open |
The output voltage of VTA2 is higher than 4.75 V, and VTA1 is less than 2.367 V for 2 seconds or more (1 trip detection logic). |

MONITOR DESCRIPTION
The ECM uses the throttle position sensor to monitor the throttle valve opening angle. If the VTA2 terminal voltage is higher than the threshold, the ECM will illuminate the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
Click here
-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON [A].
- Turn the Techstream on.
- Start the engine.
- With the vehicle stationary, fully depress and release the accelerator pedal [B].
- Idle the engine for 2 seconds or more [C].
- Enter the following menus: Powertrain / Engine / Trouble Codes [D].
-
Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P022015.
-
Check the DTC judgment result.
Techstream Display
Description
NORMAL
ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result is NORMAL, the system is normal.
- If the judgment result is ABNORMAL, the system is malfunctioning.
- If the judgment result is INCOMPLETE, perform steps [B] through [D] again.
-
[A] to [D]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
FAIL-SAFE
When this DTC is stored, the ECM enters fail-safe mode. During fail-safe mode, the ECM cuts the current to the throttle actuator, and the throttle valve is returned to a 7.5° throttle valve opening angle by the return spring. The ECM then adjusts the engine output by controlling the fuel injection (intermittent fuel-cut) and ignition timing, in accordance with the accelerator pedal angle, to allow the vehicle to continue running at a minimal speed. If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly.
Fail-safe mode continues until a pass condition is detected, and the ignition switch is turned off.

CAUTION / NOTICE / HINT
HINT:
Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE

READ VALUE USING TECHSTREAM (THROTTLE POSITION SENSOR NO.2 VOLTAGE) |
|
*a |
Front view of wire harness connector (to Throttle Body with Motor Assembly) |
(a) Disconnect the throttle body with motor assembly connector.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the Techstream on.
(e) Enter the following menus: Powertrain / Engine / Data List / Throttle Position Sensor No.2 Voltage.

|
Throttle Position Sensor No.2 Voltage |
(f) According to the display on the Techstream, read the Data List.
HINT:
Use the snapshot function to record the value displayed or make a note of it.
(g) Turn the ignition switch off.
(h) Turn the Techstream off.
(i) Connect terminals 3 (VTA2) and 4 (E2) of the throttle body with motor assembly connector on the wire harness side.
NOTICE:
If the VTA2 terminal voltage or the resistance between VTA2 and E2 is abnormal and terminals 3 (VTA2) and 4 (E2) of the throttle body with motor assembly connector are connected, excessive current may flow through the circuit. In this case, do not connect the terminals.
(j) Turn the ignition switch to ON.
(k) Turn the Techstream on.
(l) Enter the following menus: Powertrain / Engine / Data List / Throttle Position Sensor No.2 Voltage.
