Error Code P2305: What It Means & What To Do?
OBD Code P2305 - Ignition Coil "B" Secondary Circuit
The trouble code P2305 can be described as
Ignition Coil "B" Secondary Circuit. The error code P2305 would start
triggering when the PCM would detect some fault in voltage of the ignition coil
‘B’. One thing which you must keep in mind that its symptoms as well as causes
would surely vary as it depends upon a number of things..

This
trouble code is generic, which would mean that it can apply to all the vehicles
which are equipped with the OBD-II or the vehicles which are made since 1996 up
to the present. The specifications on the definition, the troubleshooting steps
as well as repairs can always vary from one vehicle make to another. This can
happen because of a lot of reasons and the mechanic should diagnose the
specific cause for this code. The P2305 trouble code would indicate that a
voltage of the ignition coil ‘B’ which is not as per the predetermined limit
has been detected by the ECM. Now when this would occur, the fault code would
be stored and there would be an illumination in the malfunction indicator
light.
What causes this problem with
the Ignition Coil "B" Secondary Circuit?
- Defaults
in the Ignition Coil 'B'
- Ignition
Coil 'B' harness might be opened or shorted
- Ignition
Coil 'B' circuit bad electrical connection
- Malfunctioning
relay or blown fuse
- Unusable
PCM
- Quirks
in the camshaft or cranksh
Replace/Repair These Parts To Fix Code P2305
- Oxygen Sensor
- Oxygen sensor plays a vital role
in anticipating the levels of oxygen measured for the optimal air to fuel
ratios for the combustion process and also for the exhaust emissions to keep
the emission levels under check. Thus, replace faulty oxygen sensor now!
- Fuel Tank Pressure
Sensor - Faulty
pressure sensor will cause hard starting, potential decrease in power,
acceleration and fuel efficiency. Thus, immediate replace is in order. Buy new
pressure sensor and replace it now!
- Powertrain Control
Module - The PCM
works as the central computer system in an automobile’s mechanism. This auto
part is the in charge of all the constituents as well as the functions
performed by them. Having such enormous importance in the operation of all the
parts means that any defect in it will affect almost every aspect of a car.
- Fuel Injector
- The fuel injectors are important
component of the fuel delivery system that helps in proper utilization of the
fuel entering the engine. This not only helps in taking care of the air to fuel
ratios in the engine, helping the combustion process but also enhances the
performance. Thus, replace faulty injector now!
- Electronic Control
Unit - The ECU is a
major component of your car's onboard computer. It's used to regulate many
systems and subsystems in your car's engine, drive train and other major
components. Visit us to buy best quality ECU online.

Easy Diagnosis Of Engine Error OBD Code P2305
Here are some steps which you should follow in order to diagnose this fault code:
Use an OBD-II scanner in order to verify that the code is present, and check for other codes for any other type of error or problem that might need attention. Use the vehicle information source to search for applicable technical service bulletins (TSB). If you locate a TSB that matches the vehicle make and model, symptoms exhibited, and the code stored, it will help you to arrive at a diagnosis. You may also need to obtain diagnostic flow charts, wiring diagrams, connector face views, connector pinout charts, component locations, and component testing procedures/specifications from the vehicle information source. All this information will be needed to correctly diagnose the stored code P2305.
After that test drive the vehicle to see if the code P2305 is reset. Drive until one of two things happens: Either the PCM enters readiness mode or the code is reset. If the code is reset, continue with the diagnosis. If it is not, you are dealing with an intermittent condition which may have to worsen before an accurate diagnosis may be achieved. Now if the code has been restored, then you must continue with the diagnosis. One should obtain connector face views, connector pin out charts, component locator charts, wiring diagrams, and diagnostic flow charts by utilizing your source of vehicle information.
A visual inspection of associated wiring and connectors should be performed. Make sure to repair or restore the wiring that has been cut, burned, or flawed. Wiring on top of the engine is often defective due to wildlife attempting to stay warm in cold climates. The DVOM should be used to inspect the voltage and ground circuits at the ignition coil. If no voltage has been detected, then you should check the system relay and associated fuses. Restore the faulty relays or blown fuses as per the requirement. If voltage and ground have been detected at the coil, examine the corresponding ground circuit at the PCM connector with the engine running. If ground pulse is detected there, then there is an open circuit between the coil as well as the PCM. If no ground pulse is discovered there, then there is some fault in the PCM or there might be PCM programming error.
Common Mistakes When Diagnosing The P2305 Code
- Most of the times the mechanics do not react properly and would just restore the ignition coils and spark plugs when in reality the wiring and connectors should be restored so that it can work properly.
