P2226 BARO SENSOR

P2226 BARO SENSOR

Description

INFOID:0000000001162671

The barometric pressure sensor is built into ECM. The sensor
detects ambient barometric pressure and sends the voltage signal to
the microcomputer.

DTC Logic

INFOID:0000000001162672

DTC DETECTION LOGIC

NOTE:
• Conditions for applying the diagnostic procedure to the stored DTCs:

The DTC is declared present after the ignition has been switched on for at least 10 seconds.

• Special note:

The barometric pressure sensor is integrated into the ECM, and cannot be separated.
