Condition for Determination

Possible Reason

Actions

Engine operation

The number of teeth entering into

ECM isn’t equal to 58 during 5

continuous cycles

1) Bad shielding of signal circuit

2) Foreign metal materials in the

58X gear ring

1) Apply

the

shielded wire

2) Clean the 58X

gear ring
