How does the ignition coil work on a car?
The ignition system on the vehicle uses individual ignition coils for each cylinder. The Engine Control Module ( ECM) controls each ignition coil operation. The ECM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.
How does the p0357 ignition coil G work?
The coil driver circuit is monitored by the PCM for faults If an open or a short is detected in the driver circuit for coil #7, a P0357 may set. Also, depending on the vehicle, the PCM may also shut down the fuel injector to the cylinder also.
Where are the spark plugs on a DTC ignition coil?
There is an individual coil for each cylinder that is controlled by the PCM (powertrain control module) It eliminates the need for spark plug wires by putting the coil right above the sparkplug. Two wires are dedicated to each coil. One is a battery feed usually from the power distribution center.
When does the PCM set the ignition coil code?
Since the secondary winding contains many more turns of wire, output voltage is increased to thousands of volts. This is enough to fire the spark plugs. The PCM sets an ignition coil control circuit code P0351-P0358 when it detects a problem with the ignition coil circuit.
Where is the ignition coil located on a car?
The COP (coil on plug) ignition system is what is used on most modern engines. There is an individual coil for each cylinder that is controlled by the PCM (powertrain control module) It eliminates the need for spark plug wires by putting the coil right above the sparkplug.
