(23) Spark Coil Primary (DTC 2300, 2301, 2303, 2304, 2306, 2307, 2309, 2310)
DTC 2300-Spark Coil #1 Primary Open/Short-to-Ground
DTC 2303-Spark Coil #2 Primary Open/Short-to-Ground
DTC 2306-Spark Coil #3 Primary Open/Short-to-Ground
DTC 2309-Spark Coil #4 Primary Open/Short-to-Ground
• Hardware: Ignition/Spark Coil (Dumb-coil ONLY)
• Enabling Conditions: Key On, Engine Running, Battery volts > 11.0
• Set Conditions: Primary circuitry of the ignition coil is an open circuit or shorted-to-ground
• Corrective Action(s): Illuminate MIL, disable closed-loop while code is active and disable fuel adaptive learn for
the rest of the key cycle.
• Emissions related fault
• Possible Causes:
Each coil driver #1, #2, #3 and #4 fires the corresponding cylinder, the 1st, 2nd, 3rd and 4th cylinder each in the
block order.
These faults will set if the ECM detects 10 coil firings in which the adaptive dwell adjustment is greater than 2 ms.
or the total dwell is greater than 14 ms. and battery voltage is greater than 11.0 V.
The purpose of these faults is to detect a short-to-ground or open circuit in the harness or an open internal to the
primary coil.
DTC 2301-Spark Coil #1 Primary Short-to-Power
DTC 2304-Spark Coil #2 Primary Short-to-Power
DTC 2307-Spark Coil #3 Primary Short-to-Power
DTC 2310-Spark Coil #4 Primary Short-to-Power
• Hardware: Ignition/Spark Coil (Dumb-coil ONLY)
• Enabling Conditions: Key On, Engine Running, Battery volts < 16.0
• Set Conditions: Primary circuitry of the ignition coil is shorted-to-power
• Corrective Action(s): Illuminate MIL, disable closed-loop while code is active and disable fuel adaptive learn for
the rest of the key cycle.
• Emissions related fault
• Possible Causes:
Each coil driver #1, #2, #3 and #4 fires the corresponding cylinder, the 1st, 2nd, 3rd and 4th cylinder each in the
block order.
These faults
will set if the ECM detects 10 coil firings in which the adaptive dwell adjustment is less than
2 ms.
or the total dwell is less than 4.0 ms. and battery voltage is less than 16.0 V.
The purpose of these faults is to detect a short-to-power in the harness or internal to the primary coil.
