(See ignition coil removal)\n(b) Remove the spark plug.\n(c) Install the spark plug to the ignition coil, and connect the ignition coil connecter.\n(d) Ground the spark plug.\n(e) Check if spark occurs while engine is being cranked.\nHINT: To prevent gasoline from being injected from injectors during this test, crank the engine for no more than 1–2 seconds at time.\nIf the spark does not occur, do the test as follows:\n\nSPARK TEST\n↓ NO\nCHECK CONNECTION OF IGNITION COIL, IGNITER\n↓ OK\nBAD → Connect securely.\n\nCHECK POWER SUPPLY TO IGNITION COIL AND IGNITER\n1. Turn ignition switch to ON.\n2. Check that there is battery voltage at ignition coil positive (+) terminal.\n↓ OK\nBAD → Check wiring between ignition switch to ignition coil and igniter.\n\nCHECK RESISTANCE OF IGNITION COIL\n(See page IG–23)\nResistance:          Cold               Hot\nPrimary          0.54 – 0.84 Ω     0.68 – 0.98 Ω\n↓ OK\nBAD → Replace the ignition coil.\n\nCHECK RESISTANCE OF CAMSHAFT AND CRANKSHAFT POSITION SENSOR\n(See page IG–24)\nResistance:          Cold               Hot\nNIPPONDENSO    835 – 1,400 Ω    1,060 – 1,645 Ω\nAISAN           985 – 1,600 Ω    1,265 – 1,890 Ω\n↓ OK\nBAD → Replace the camshaft and crankshaft position sensor.\n\nCHECK IGT SIGNAL FROM ECM\n(See page EG–519)\n↓ OK\nBAD → Check wiring between ECM, and igniter, and then try another ECM.\n\nTRY ANOTHER IGNITER\n\nADJUST IGNITION TIMING\n(See ignition timing inspection and adjustment)","image":"https://tsrm.sasquatchvc.com/images/mk4/IGTE/IGTE_003.png","url":"https://tsrm.sasquatchvc.com/mk4/tsrm/IGTE/3","prev":{"page":2,"url":"https://tsrm.sasquatchvc.com/mk4/tsrm/IGTE/2","api":"https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/2"},"next":{"page":4,"url":"https://tsrm.sasquatchvc.com/mk4/tsrm/IGTE/4","api":"https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/4"},"section_url":"https://tsrm.sasquatchvc.com/mk4/tsrm/IGTE","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/1","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/2","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/3","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/4","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/5","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/6","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/7","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/8","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/9","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/10","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/11","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/12","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/IGTE/13"],"note":"OCR transcript of a scanned Toyota factory manual page; verify critical values (torque specs, part numbers) against the image."}
