DTC P2228, P2229 BARO SENSOR

PFP:23731

Description

EBS01512

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

On Board Diagnosis Logic

EBS01513

The MI will not light up for these self-diagnoses.

DTC Confirmation Procedure
