9-24 ELECTRICAL SYSTEM Step 5 1) Inspect the ignition coil/plug caps. (9-26) Is the ignition coil/plug cap OK? YES Go to Step 6. NO • Poor connection of the ignition coil/plug cap(-s). • Faulty ignition coil/plug cap(-s). Step 6 1) Measure the crankshaft position sensor peak voltage and its resistance. (9-27 to -28) NOTE: The crankshaft position sensor peak voltage inspection is applicable only with the multi circuit tester and peak volt adaptor. Is the peak voltage and resistance OK? • Faulty ECM YES • Open or short circuit in wire harness • Poor connection of ignition couplers NO • Faulty CKP sensor • Metal particles or foreign material being stuck on the CKP sensor and rotor tip E L P M A S
