QUESTION

Is the measured value less than 53.3 kPa (400 mmHg, 15.8 inHg)?

Yes No

Even if the malfunction indicator light illuminates, 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 open or short circuit of harness or temporary poor contact of connector may be the cause.
