DIAGNOSTICS
DTC Detecting Condition
The ECM observes the pressure in the secondary air passage
using the pressure sensor located on the air switching valve in
ECM
the secondary air injection system.
If there is a defect in the sensor or the sensor circuit, the voltage
VC
level will deviate from the normal operating range, the ECM in-
terprets this deviation as a defect in the pressure sensor circuit
and sets a DTC.
