CHECK SECONDARY AIR PIPING PRESSURE.

1) Turn the ignition switch to ON.

2) Using the Subaru Select Monitor, read secondary air piping pressure data, and compare with the actual atmospheric pressure.

NOTE:

For detailed operation procedures, refer to “READ CURRENT DATA FOR ENGINE”.

QUESTION

Is the actual difference with atmospheric pressure 50 mmHg (6.7 kPa, 2.0 inHg, 0.97 psig) or more?

Yes No

Even if DTC is detected, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

NOTE:

In this case, temporary poor contact of connector may be the cause.
