Diagnostic Procedure 23 (Cont'd)
1
INSPECTION START
2
A CHECK POWER SUPPLY. 1) Disconnect crank angle sensor harness connector. 2) Turn ignition switch "ON". 3) Check voltage between terminal b and ground. Voltage: Battery voltage
N.G.
Repair harness or connectors.
O.K.

4
C CHECK INPUT SIGNAL CIRCUIT. 1) Reconnect crank angle sensor harness connector. 2) Start engine. 3) Read crank angle sensor signals in "DATA MONITOR" mode with CONSULT. rpm: M/T: 750 +/- 50, A/T: 800 +/- 50
5
OR 1) Disconnect E.C.U. harness connector. 2) Check harness continuity between terminal c and E.C.U. terminals 31, 40 (1° signal), terminal d and E.C.U. terminals 22, 30 (180° signal). Continuity should exist.
N.G.
same as step 2
O.K.
6
CHECK COMPONENT (Crank angle sensor). Refer to "Electrical Components Inspection". (See page EF & EC-347.)
N.G.
Replace crank angle sensor.
O.K.
