Toyota Yaris: Sfi System / Barometric Pressure Sensor "A" Circuit Short to Ground (P222611,P222615)

Toyota Yaris XP210 (2020-2025) Reapir and Service Manual / Engine & Hybrid System / G16e-gts (engine Control) / Sfi System / Barometric Pressure Sensor "A" Circuit Short to Ground (P222611,P222615)

DESCRIPTION

The atmospheric pressure sensor is built into the ECM. The ECM provides optimal control in response to atmospheric pressure fluctuations.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	MIL	Note
P222611	Barometric Pressure Sensor "A" Circuit Short to Ground	Short in atmospheric pressure sensor circuit (ECM internal malfunction) (1 trip detection logic).	ECM	Comes on	SAE: P2228
P222615	Barometric Pressure Sensor "A" Circuit Short to Battery or Open	Open or short in atmospheric pressure sensor circuit (ECM internal malfunction) (1 trip detection logic).	ECM	Comes on	SAE: P2229

MONITOR DESCRIPTION

The ECM calculates the atmospheric pressure from the atmospheric pressure sensor output voltage. When the atmospheric pressure sensor output voltage is outside of the normal range, there may be an open or short in the atmospheric pressure sensor circuit or the atmospheric pressure sensor may be malfunctioning. In this case, the ECM will illuminate the MIL and store a DTC.

MONITOR STRATEGY

Required Sensors/Components	Atmospheric pressure sensor (ECM)
Frequency of Operation	Continuous

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS 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.
Turn the GTS on.
Wait 5 seconds or more.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the 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: P222611 or P222615.

Check the DTC judgment result.

GTS Display	Description
NORMAL	DTC judgment completed System 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.

CAUTION / NOTICE / HINT

HINT:

Read Freeze Frame Data using the GTS. 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

1.	CHECK DTC OUTPUT

(a) Read the DTCs.
