What is ignition coil H?

OBD Code P0358 – Ignition Coil “H” Primary/Secondary Circuit Malfunction. <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.

What is ignition coil h primary secondary circuit?

It includes the battery, ignition switch, primary coil winding, a triggering mechanism (such as a crankshaft sensor) and switching device (such as an ignition module or ECU). The high voltage side of the system is called the secondary circuit. On modern vehicles it includes the coil pack and spark plugs.

What is code po358?

OBD-II Code P0358 is defined as a Ignition Coil “H” Primary/Secondary Circuit. The ignition coil or coils are responsible for igniting the air/fuel mixture inside the combustion chambers. Without reliable performance from the ignition coil(s) the vehicle will stumble and misfire.

What is ignition coil f primary secondary circuit malfunction?

What Does the P0356 Code Mean? Diagnostic trouble code (DTC) P0356 stands for “Ignition Coil F Primary/Secondary Circuit Malfunction.” If the PCM perceives a possible problem in one of the ignition coils or if it loses control of the circuit, it logs error code P0356.

How do you fix po358?

What repairs can fix the P0358 code?

  1. Replacing the ignition coil.
  2. Repairing a loose electrical connection to the ignition coil.
  3. Replacing the wiring and/or connectors for the ignition coil circuit.
  4. Replacing or reprogramming the PCM (rare)

What is ignition coil E?

Diagnostic trouble code (DTC) P0355 stands for “Ignition Coil “E” Primary/Secondary Circuit.” It indicates that the powertrain control module (PCM) detected a problem in either the primary (computer side) or the secondary (spark plug side) #5 ignition coil “E” circuit.

How do you test a GM coil pack with a multimeter?

Turn the multimeter on. Attach the its red lead to the right terminal, then attach the black lead to the left terminal. Read the voltage displayed on the multimeter. Your coil pack is properly powered if the reading is 11 to 12 volts.

How do I fix code po356?

What repairs can fix the P0356 code?

  1. Repairing or replacing the ignition coil.
  2. Repairing or replacing a shorted or open wire in the ignition coil driver circuit.
  3. Cleaning, repairing, or replacing the connector if corrosion has damaged it.

What causes P0355?

What the P0355 code means. The engine’s ignition coils’ job is to ignite the air/fuel mix in each of the engine’s combustion chambers. When one of these ignition coils (in this case, coil B) has an electrical problem, the engine will not be able to run smoothly, and it may hesitate or misfire.
