Best way to test is connect to car and see if it gives spark with engine turning, because it gets ground pulse from the distributer,if pulse id not coming to ignition coil, then you need to change distributor.

2002 tracker what causes it to stall out going down the road....it acts like its missing out and dies


What engine does it have ? 1.6 L , 2.0 L , 2.5 L . A crankshaft position sensor , coil pack , I would say that you have an ignition system problem . The only way to know for sure is have it checked .Go on youtube an check out some videos on trouble shooting ignition systems from scanner Danner ,he is a teacher of automotive engine electrical diagnostics . Then go to www.bbbind.com/ for free wiring diagrams an do some voltage tests. The PCM uses reference pulses from the CMP sensor in order to determine engine speed. The PCM cannot operate the ignition system, or the fuel injectors, without the engine speed signal from the CMP.
The ignition coils supply spark to 2 engine cylinders, and spark plugs, at the same time. When the PCM signals the ignition module to interrupt the current flow in the primary coil windings, the electrical field around the primary coil collapses and a high voltage is induced in the secondary coil. The secondary coil voltage travels simultaneously from both coil output terminals, to the spark plugs, and across the gap of each spark plug to the engine block. The CKP sensor signal is used by the PCM for engine misfire detection.

The test fails when the Engine Control Module (ECM) does not receive a valid pulse signal from the ignition coil.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine may be harder to start
- Engine hesitation
- Rough engine idle
P0350 Hyundai Description
The ignition signal from the Engine Control Module (ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

IGNITION COIL TESTING DODGE 2.7 INTREPID 2004


to check ignition coil, you need a digital volt meter put it on the ohms scale check primary resistance across primary coil positive terminal to secondary high voltage terminal. primary resistance should be 0.6 to 0.9 ohms and secondary resistance should be 6 to 9 kilo ohms. if you see zero ohms more likely ignition coil has open circuit.

How to test ignition coil


You need a sensitive good quality ohm meter, preferably with a zero adjustment, as these readings can be quite low.

The primary resistance is measured between the positive and negative terminals on the coil, and should read about 0.5 ohms (it varies with the model of car).

The secondary is measured usually between the positive terminal and the high tension terminal (thick lead), and is usually about 10 Kilo ohms (again it varies from car to car)

These are usually measured with the coil cool.

Need diagram for ignition coils for 2001 Mazda Tribute. Tripping code: P0351 Ignition Coil Primary/Secondary Malfunction???? Thanks


Same as Ford Escape.
P0351 - Ignition Coil A - Primary/Secondary Circuit

Cylinder #1, Pin 26 at the PCM, computer.

I would replace the coil on the plug (COP) for that cylinder and see if its' ok. If not, then it is possible that the bad coil took out the driver in the PCM. The test at Pin 26 to see if the light blinks, must be done with the correct tester or it will damage the PCM.

Hope it's the coil.

report results.

How to check ignition coil?


If you suspect a malfunctioning ignition coil, check the resistance of primary and secondary windings. Do this when the coil is hot, and again when it is cold. Also measure from the case to each connector. The primary windings should have a very low resistance, typically from a few tenths of an ohm to a few ohms. The secondary windings have a higher resistance, typically in the 10,000 to 13,000 ohm range. To get the actual figures for a specific coil, check the manufacturer's specs. But as a rule of thumb, primary windings range from a few tenths of an ohm to a few ohms, and secondary winding may be 10 ohms or more.

P1370 and p1350 trouble codes


P1370 Ignition Control (IC) Module 4x Reference too many pulses

P1350 Ignition Control System

Ok, these codes are signaling a malfunction within the Ignition control module. it is sending way to many signals to the coil. i recommend testing the coil for damage and irregular resistance. i will explain how to do this below. i would replace the module as well. The control moduel is Located Under hood, center, rear engine area, above valve cover, mounted in base of ignition coil pack

Ignition Coil Test Procedures__

Ignition Coil Resistance

* with the key off and the battery lead to the ignition coil disconnected, use an Ohmmeter to measure the primary and secondary winding resistance of the ignition coil. when checking the resistance across the windings, pay particular attention to the meter reading. if the reading is out of specifications, even if it is only slightly out, the coil or coil assembly should be replaced.
* To check the primary windings, calibrate an ohmmeter on the X1 scale and connect the meter leads to the primary coil terminals to test the winding.

* An infinite ohmmeter reading indicates an open winding. The winding is shorted if the meter reading is below the specified resistance. Most primary windings have a resistance of 0.5 to 2 ohms, but the exact manufacturer's specifications must be compared to the meter readings.
* To check the secondary winding, calibrate the meter on the X1,000 scale and connect it from the coil's secondary terminal to one of the primary terminals.

# A meter reading below the specified resistance indicates a shorted secondary winding. An infinite meter reading proves that the winding is open.
# In some coils, the secondary winding is connected from the secondary terminal to the coil frame. When the secondary winding is tested in these coils, the ohmmeter must be connected from the secondary coil terminal to the coil frame or to the ground wire terminal extending from the coil frame. Many secondary windings have 8,000 to 20,000 ohms resistance, but the meter readings must be compared to the manufacturer's specifications. The ohmmeter tests do not indicate such defects as defective insulation around the coil windings, which causes high-voltage leaks.
