P0359 OBD Error Code: Problem & Solutions
OBD Code P0359 - Ignition Coil ?I? Primary/Secondary Circuit Malfunction
This diagnostic
fault code is a generic powertrain code, which means that it would apply to the
OBD-II equipped vehicles. The specific repair steps can vary as it depends upon
the vehicle make and model.
The P0359 fault
code can be defined as Ignition Coil ?I? Primary/Secondary Circuit Malfunction.

Willing to learn
more about P0359 trouble code? It is the ignition system which would convert
the battery voltage into the high voltage which is used to ignite the cylinder
air/fuel mixture. The side of the system which provides low voltage is called
the primary circuit. This would include the battery, ignition switch, primary
coil winding, crankshaft sensor as well as ECU. On the other hand, the high
voltage side of this system is known as secondary circuit. In the modern
vehicles, it would include the coil pack as well as the spark plugs. The low
primary circuit voltage is converted into the high secondary voltage with the
help of coil pack which is needed to fire the plugs. The coil pack is generally
a transformer which contains coils of wire inside it.
In the primary
side there are hundred turns of wire while the secondary side has thousands.
Current would be then applied to the primary side of the coil, which would thus
create a magnetic field around the winding. The current is then interrupted
with the help of a switching device which is generally the PCM. This would cause
the magnetic field to collapse, inducing the voltage into the winding. Similarly,
the collapsing magnetic field would create a voltage in the secondary winding.
Since there are many more turns of wire in the secondary winding, then the
output voltage would be increased to thousands of volts. This would be enough
to ignite the spark plugs.
What causes this problem with the Ignition Coil ?I? Primary/Secondary
Circuit Malfunction?
- There
can be short to voltage or ground on COP driver circuit

Replace/Repair These Parts To Fix OBD Code P0359
- Ignition Coil - Defective car
Ignition Coil can be a major reason why P0359 code depicts. So, make sure to
replace it online so that you don?t have to face any further issues.
- Powertrain Control Module - Everything is
okay with the Ignition Coil and still OBD code P0359 triggering? Then there
must be some defects in Powertrain Control Module. Replace them as soon as
possible.
- Engine Control Module - P0359 code
flashing? Get your Engine Control Module inspected from a mechanic.
- Fuel Ignition System - If everything
is alright with Engine Control Module, then there is surely some defect in Fuel
Ignition System parts. Get it replaced before the situation gets worse.
- Engine Wiring Connector - P0359 code can
display due to some issues in the Engine Wiring Connector. So, it is very
important to replace the Engine Wiring Connector with us at equitable prices.
- Spark Plug - Do you
remember when was the last time you got your car Spark Plug checked up? A dirty
Spark Plug can cause a lot of issues like displaying P0359 code.
- Electronic Control Unit - Poor Electronic Control Unit can cause a lot of difficulties, so why not get it replaced at time?
- Throttle Body - Are there some
faults in your Throttle Body? Don?t waste time and get them replaced or else
P0359 code can turn up.

Easy Diagnosis Of Engine Error OBD Code P0359
Here are some
steps which you should follow in order to diagnose this fault code:
First
of all, you must verify the code with a handheld OBD II scanner. The technician
should clear the code and test drive the vehicle, checking if the code resets,
as well as for consistent or intermittent misfires. If you find out that the
misfire is not constant, the mechanic should inspect the wiring and connector
to the ignition coil properly.
This
problem can be caused due to a loose connection or damaged wire. If the misfire
is constant, the mechanic should check for signal to the affected coil using a
scope to see the signal?s visual pattern. Alternatively, a voltmeter can be
used to verify that the reading for the coil is between 5 and 20. If so, the
coil is most likely faulty. If not, then there is a short somewhere in the
wiring that must be located and repaired. The faulty or failed coils are the
most common culprits in this issue.
Common Mistakes When Diagnosing The P0359 Code
The
technicians might report the maintenance tune ups frequently to correct this
fault code. It doesn?t mean that the tune up was overdue, but there might be a
need to perform a thorough diagnosis so that the exact malfunction can be pinpointed.
