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 barometric 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 fault condition, and reperform the check.

NOTE:

In this case, there may be a temporary connector contact failure.
