CHECK CURRENT DATA.

1) Start the engine.

2) Read the data of DPF pressure difference sensor signal using Subaru Select Monitor.

NOTE:

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

QUESTION

Is DPF differential pressure between inlet and outlet 107 kPa (802.6 mmHg, 31.6 inHg) 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.
