Testing & Diagnostics ~210 words
  1. Turn ignition off. Disconnect crankshaft position sensor connector. (Схема №1), (Схема №3) or (Схема №4) for CKP sensor and ECM locations. Use DVOM to measure resistance between CKP sensor harness connector terminals No. 1 (Yellow wire) and 2 (Black wire) going to ECM. (Схема №10) If resistance is between 150-250 k/ohms, go to next step. If resistance is not as specified, repair faulty circuit in Yellow or Black wire between CKP sensor and ECM. (Схема №11)for ECM terminal identification. See appropriate wiring diagram in «WIRING DIAGRAMS»(ref-3491) article. Go to step 3.
  2. Connect SST 86 11 857 test light (Схема №9) or equivalent between positive battery terminal and CKP sensor connector terminal No. 3 (Black wire). If test light illuminates, replace CKP sensor. If test light does not illuminate, repair open circuit between CKP sensor connector terminal No. 3 and ECM harness connector terminal No. 22 (Black wire). Go to next step.
  3. Use scan tool to clear DTCs. Drive vehicle for 5 minutes under varying loads and engine RPM. Recheck for any stored DTCs. If DTC P0336 or P0337 is present, substitute known good ECM and retest system. See «ENGINE CONTROL MODULE (ECM)»(ref-2997-S17585372472000041700000) under COMPUTERIZED ENGINE CONTROLS in REMOVAL, OVERHAUL & INSTALLATION article.
