15-12 ELECTRICAL SYSTEM
Step 4
1) Measure the ignition coil/plug cap resistance. (15-14)
Is the ignition coil/plug cap resistance OK?
YES Go to Step 5.
NO Faulty ignition coil/plug cap
Step 5
1) Measure the CKP sensor peak voltage and its resistance. (15-15, -16)
Are the peak voltage and resistance OK?
YES Go to Step 6.
• Faulty CKP sensor
NO
• Metal particles or foreign material being stuck on the CKP sensor and rotor tip
Step 6
1) Measure the crankshaft rotation signal sensor peak voltage and its resistance. (15-15, -16)
Are the peak voltage and resistance OK?
YES Go to Step 7.
• Faulty crankshaft rotation signal sensor
NO • Metal particles or foreign material being stuck on the crankshaft rotation signal
Step 7
1) Check the stator. (15-9)
Is the stator OK?
YES Go to Step 8.
NO Faulty stator
Step 8
1) Measure the engine stop switch resistance. (15-16)
Is the resistance OK?
• Faulty ECM
YES
• Open or short circuit in wire harness
NO Faulty engine stop switch
