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). |
|
Comes on |
DTC stored |
SAE Code: P0223 |
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
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for at least 30 seconds.
- Turn the power switch on (IG) [A].
- Turn the Techstream on.
-
Put the engine in Inspection Mode (Maintenance Mode).
Click here
- Start the engine.
-
With the vehicle stationary, fully depress and release the accelerator pedal [B].
HINT:
During charge control, the engine speed is set at idle. Therefore, the engine speed will not increase when the accelerator pedal is depressed. In this case, perform step [B] after charge control has completed.
- 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.

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.
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 engine torque request signal sent from the hybrid vehicle control ECU assembly, to allow the vehicle to continue being driven 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 power switch is turned off.

CAUTION / NOTICE / HINT
NOTICE:
-
Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

(Select Powertrain in Health Check and then check the time stamp data.)

-
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

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

(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.
