![]() This section will give you an overview of the basic working theory of the power transistor and will help you see the 'why' of the tests in this article. ![]() If you haven't read the section: How Does The Power Transistor Work?, do so now. Quantity per car: 1 PRICE: 257. In order to turn the key to the 'off' position and release it, you must jiggling the shift lever hard right and left several times while the shifter is in the 'park' position. Price Duralast Multi Pack Ignition Coil C1406-6 Part C1406-84 Limited-Lifetime Warranty Check if this fits your 2005 Nissan/Datsun Altima Notes: Direct Ignition Coil Kit. The ignition key will not turn fully to the 'off' position and release the key when the car is placed in park, without a struggle. The very first thing you'll do, to test if the power transistor (igniter) is working or not, is to make sure the distributor is getting power (12 Volts). 2005 Nissan Altima 2.5, automatic, 4-speed. TEST 1: Making Sure The Power Transistor Is Getting Power Shop for the best Ignition Coil for your 2005 Nissan Altima, and you can place your order online and pick up for free at your local OReilly Auto Parts. TIP 5: If the igniter (power transistor) is fried, you'll have to replace the entire distributor, since it's not sold separately. TIP 4: The igniter (power transistor) is part of the camshaft position sensor and is located inside the distributor. I recommend that you start your power transistor (igniter) diagnostic by first doing the ignition coil test found here: 2.4L Nissan Ignition Coil Test (97-01). The Check Engine Light usually illuminates when the computer detects a problem with any of its sensors or circuits. An illuminated Check Engine Light is one possible symptom of a problem with the ECM. TIP 3: You need to test for spark first, before attempting this power transistor test, because if you have spark, the power transistor is good and doing its job. SOURCE: Crank position sensor for 2003 Nissan Altima a crank position sensor, sends a signal to pcm about crankshaft position signal, the sensor controls spark timing and firing order. A bad or failing ECM may produce any of the following 5 symptoms to alert the driver of a potential problem. TIP 2: The battery in your 2.4L Nissan Altima must be fully charged, since you'll be cranking the engine for some of the tests. TIP 1: Since this is an on-car test of the power transistor (ignition control module) and is tested in action, you'll be working around a cranking engine. It was a fun car to begin with and plenty of power and torque for a 25,000 car. You can find this tutorial in Spanish here: Cómo Probar El Módulo De Encendido (1997-2001 2.4L Nissan Altima) (at: ). 2005 Nissan Altima 3.5 SE 4dr Sedan (3.5L 6cyl 5A) I have a 2005 altima SE 3.5 with 80K miles.
