Note

P222615

Barometric Pressure Sensor "A" Circuit Short to Battery or Open

Diagnosis condition:

  • Ignition switch ON

Abnormal condition:

  • Open or short in atmospheric pressure sensor circuit (ECM internal malfunction).

Malfunction time:

  • 3 seconds or more

Trip logic:

  • 1 trip detection logic

Detection conditions:

  • Continuous

Sensors/components used for detection:

  • Atmospheric pressure sensor

ECM

Comes on

  • SAE Code: P2229
  • DTC for Mexico Models: Applies

MONITOR DESCRIPTION

When the ignition switch is turned ON and the output voltage of the atmospheric pressure sensor is higher than 4.48 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.

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.
