IG-3 IGNITION (2JZ-GTE) - IGNITION SYSTEM SPARK PLUG CLEANER IG0152 (f) Clean the spark plugs. If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner. Air pressure: Below 588 kPa (6 kgf/cm2, 85 psi) Duration: 20 seconds or less HINT: If there are traces of oil, remove it with gasoline before using the spark plug cleaner. (g) Using a 16 mm plug wrench, reinstall the 6 spark plugs. Torque: 18 N·m (180 kgf·cm, 13 ft·lbf) (h) Reinstall the ignition coils assemblies. (See page IG-7 ) Ohmmeter P11795 3. INSPECT IGNITION COILS (a) Remove the No.3 timing belt cover. (b) Disconnect the ignition coil connectors. (c) Using an ohmmeter, measure the resistance between the terminals. Primary coil resistance: Cold 0.54 - 0.84 Ω Hot 0.68 - 0.98 Ω If the resistance is not as specified, replace the ignition coil. (d) Reconnect the ignition coil connectors. (e) Reinstall the No.3 timing belt cover. Ohmmeter P12177 4. INSPECT CAMSHAFT POSITION SENSORS (a) Disconnect the camshaft position sensor connectors. (b) Using an ohmmeter, measure the resistance between ter- minals. Resistance: Cold 835 - 1,400 Ω Hot 1,060 - 1,645 Ω If the resistance is not as specified, replace the camshaft posi- tion sensor. 1997 SUPRA (RM502U) Author : Date : 1497
