How do you change ignition coils on a Nissan?
Park your Nissan on level ground. Allow the engine to cool down. Pull the hood release under the dashboard and open the hood. Locate the battery in the engine bay. Disconnect the negative battery terminal. Watch a video to learn how to perform this step.
How can I tell if my Nissan coil is still running?
If the coil has a plug-in connector instead of the studs, unplug the connector for the coil after releasing any locking tab on the connector. Place one lead from the multi meter on the negative post or terminal of the coil. Place the second lead on the positive post or terminal and note the reading on the meter.
How to test the Nissan D21 power transistor?
How To Test The Power Transistor 1992-1994 Nissan D21 Pickup. How To Test The Crank Angle Sensor (1990-1996 2.4L Nissan Pickup). In the next page you’ll find Part 2, which focuses on the Power Transistor (Ignition Control Module) and Ignition Coil.
Where is the crank angle sensor on a Nissan D21?
Here’s a simplified ignition system wiring diagram for the 1990, 1991, 1992, 1993, and 1994 2.4L Nissan D21 Pickup. This is Part 1 and focuses on the crank angle sensor inside the distributor. The crank angle sensor is the defacto crankshaft position sensor that the PCM uses to trigger the power transistor.
Can you test the ignition coil on a Nissan?
Testing the ignition coil on your Nissan car or truck is a project that you can do at home and save yourself a large diagnostic charge at the dealer. Though the coil produces electricity, testing it involves resistance of the coil windings.
How do you disconnect a Nissan coil?
Disconnect the high-tension cable from the coil by pulling it straight off the coil tower. Lay it aside and disconnect the wires attached on either side of the coil tower. Use a wrench to loosen the nuts and remove them along with the wires.
Where is the high tension cable on a Nissan coil?
The coil may be a cylinder or a square block but it will always have a high-tension cable attached to it. This cable looks like spark plug wire and runs to the center of the distributor cap. Disconnect the high-tension cable from the coil by pulling it straight off the coil tower.
What should secondary resistance be on Nissan coils?
This is the secondary resistance and should be between 7500 and 10500 ohms on most cars. Reconnect the connections to the coil if the test indicates a properly functioning unit. If the coil shows values outside the ranges listed, the coil needs further testing or replacing.
