Nissan 22433-53F00 Ignition Coil Assembly

You can Select Your Vehicle to check if 22433-53F00 fits your vehicle.

To start with, the check is carried out for the 1982-83 200SX with the Z series engine. We should begin by testing the supply power circuit, this is done by taking off the connector from the top of the IC unit and putting the ignition on when all is in order to be sure that there are 12 volts at every terminal; if not, then fix it. Then we have to examine primary windings of an ignition coil; this can be done by disconnecting the harness connector from negative coil terminal and measuring resistance between positive and negative terminals of a coil using an ohmmeter; if resistance goes beyond 1.04-1.27 ohms range, replace a coil. It's also necessary to disable an electronic fuel injection system so that you cannot start an engine, unplug a high tension cable from a distributor cap and hold it about 1/4 inch away from an engine block while a friend will be cranking an engine with a starter motor so as to observe whether there is any spark jumping from this cable onto an engine block or ground. Models such as 1984-88 200SX, 1989-92 240SX, and Stanza have more advanced computer-controlled ignition systems. For primary resistance on any Stanza model after 1982 which should read between .84 and 1.02 ohms or for Stanza models manufactured after '87 that come equipped with "Mold type" coils, put your ohmmeter leads across these two terminals at bottom part of revolutionize assembly, which should read between .8-1.0 ohm. In case they are higher than required then replace them since they will damage other parts of your vehicle's electrical system. If you turn off your car's ignition key while removing your high-tension wire from its spark plug connections on one end and primary wiring on another end then measure resistances across the primary and central terminal, an ohmmeter will register anything between 8,200 to 12,400 ohms before you replace any ignition coil whose internal resistance falls outside this range. Newer vehicles may have a power transistor along with its coil for amplification of signals that comes from ECU; some modern cars use a power transistor to amplify the ignition signal from the ECU and this is combined with the ignition coil as one unit. Finally, when changing your coil assembly, disconnect and mark off all wiring connections, remove the old coil assembly, if applicable transfer the mounting bracket of the coil mounting bracket and then ensure that you reinstall properly everything inclusive of new coil assembly with its corresponding electrical connections.
