TROUBLE DIAGNOSES
Diagnostic Procedure 23 (Cont'd)
Diagnostic Procedure 23 — Crank Angle Sensor (Cont'd)
1
INSPECTION START
2
CHECK POWER SUPPLY.
1) Disconnect crank angle sensor harness connector.
2) Turn ignition switch "ON".
3) Check voltage between terminal e and ground.
Voltage: Battery voltage
N.G.
Check the following.
Check the following.
• Harness connectors F21, M17
• Harness connectors M59, E55 (L.H.D. models)
• Harness connectors M3, E1 (R.H.D. models)
• Harness continuity between crank angle sensor and E.C.C.S. relay
If N.G., repair harness or connectors.
O.K.
3
CHECK GROUND CIRCUIT.
1) Turn ignition switch "OFF".
2) Check harness continuity between terminal f and engine ground.
Continuity should exist.
N.G.
Repair harness or connectors.
O.K.
4
CHECK INPUT SIGNAL CIRCUIT.
[With CONSULT]
1) Reconnect crank angle sensor harness connector.
2) Start engine.
3) Read crank angle sensor signals in "DATA MONITOR" mode with CONSULT.
rpm: 800 ± 50
— OR —
[Without CONSULT]
1) Disconnect E.C.U. harness connector.
2) Check harness continuity between crank angle sensor terminal d and E.C.U. terminals 22, 30 (180° signal).
Continuity should exist.
N.G.
same as step 3
O.K.
5
CHECK COMPONENT (Crank angle sensor). Refer to "Electrical Components Inspection". (See page EF&EC-171 - 180)
N.G.
Replace crank angle sensor.
O.K.
6
Check E.C.U. pin terminals for damage or poor connection of E.C.U. harness connector.
