P222611
|
Barometric Pressure Sensor "A" Circuit Short to Ground
|
Diagnosis condition:
Abnormal condition:
-
Short in atmospheric pressure sensor circuit (ECM internal malfunction).
Malfunction time:
Trip logic:
Detection conditions:
Sensors/components used for detection:
-
Atmospheric pressure sensor
|
ECM

MONITOR DESCRIPTION
When the ignition switch is turned ON and the output voltage of the atmospheric pressure sensor is less than 1.16 V for 3 seconds or more, the ECM determines that the atmospheric pressure sensor circuit is malfunctioning and illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN
-
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.
-
Turn the Techstream on.
-
Wait 5 seconds or more [A].
-
Enter the following menus: Powertrain / Engine / Trouble Codes [B].
-
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.
-
Proceed to the next screen and enter the DTC to be checked.
-
Check the DTC judgment result.

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
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read the DTCs.
