30 Testing and adjusting
a Precautions for disconnecting connector
The direction of the lock of the connector
varies with the tightened position of the
sensor and the lock may be in a direction
in which it is difficult to reset (on the under-
side or engine side).
In this case, pinch the lock in direction (a)
with bent-nose nippers [1] (commercially
available), and the lock is reset.
Since the lock clicks when it is reset, dis-
connect the connector after a click is heard.
a Precautions for connecting connector
Take care not to connect the connector
reversely.
Engage lock (e) on the wiring harness side
with triangular notch (f) on the sensor side
(Do not engage lock (e) with square guide
(g) on the opposite side of triangular notch
(f)).
