* The power take-off (PTO) is disabled, where applicable.
* The cylinder deactivation is not in progress, where applicable.
* DTCs P0300-P0308 run continuously when the above conditions are met.
Conditions for Setting the DTC
DTC P0300
The ECM is detecting a crankshaft speed change indicating a random misfire is occuring that exceeds mandated emission level standards or is at
catalytic converter damaging levels.
DTC P0301, P0302, P0303, P0304, P0305, P0306, P0307, or P0308
The ECM is detecting a crankshaft speed change indicating a single cylinder misfire is occuring that exceeds mandated emission level standards or
is at catalytic converter damaging levels.
Action Taken When the DTC Sets
* DTCs P0300-P0308 are Type B DTCs.
* When the MIL is flashing the fuel injector may be disabled for the misfiring cylinder to protect the catalytic converter.
* Depending on the conditions that set the DTC, the engine may go into Open Loop.
Conditions for Clearing the MIL/DTC
* DTCs P0300-P0308 are Type B DTCs.
* The DTC must run and pass under the same operating conditions that were present when the DTC failed.
Diagnostic Aids
* Ensure that each fuel injector is connected to the proper fuel injector harness connector.
* A misfire may only occur when the engine is operating under a load or when the engine is cold.
* A high resistance condition on any ignition control (IC) circuit can cause an engine misfire P0300-P0308 DTC to set without setting an IC
circuit P0351-P0358 DTC.
* This test procedure requires that the vehicle battery has passed a load test and is completely charged. Refer to Battery Inspection/Test (See:
Starting and Charging/Testing and Inspection/Component Tests and General Diagnostics/Battery Inspection/Test).
* A misfire DTC could be caused by an excessive vibration from sources other than the engine. Inspect the following for possible sources of
vibration:
- A tire or wheel that is out of round or balance
- Variable thickness brake rotors
- An unbalanced drive shaft
- Certain rough road conditions
- A damaged accessory drive component or belt
- A damaged reluctor wheel
- The Crankshaft Position System Variation Learn procedure may need to be performed.

Diagnostic Aids
Any loading of the engine that lowers engine RPM, such as with partial application of the clutch, A/C cycling etc., during the first 17 s of engine
run time may set this DTC.
Circuit/System Verification
1. Allow the engine to cool.
2. Start and idle the engine for at least 2 min.
3. DTC P1400 should run and pass.
Circuit/System Testing
* Inspect the air intake system for the following:
- Damage, restriction, or modification
- Dirty or deteriorating air filter element
- Crankcase ventilation system for correct operation-Refer to Crankcase Ventilation System Inspection/Diagnosis (See: Powertrain
Management/Emission Control Systems/Positive Crankcase Ventilation/Testing and Inspection).
- Water intrusion
- Vacuum leak and other un-metered air downstream of the mass air flow (MAF) sensor
- Intake manifold leak
* Inspect the exhaust system for the following:
- Water intrusion
- Exhaust leak
- Damaged, restricted, modified or enhanced exhaust system-Refer to Symptoms - Engine Exhaust (See: Engine, Cooling and
Exhaust/Exhaust System/Testing and Inspection/Symptoms - Engine Exhaust).
* Inspect the engine mechanical for items that could alter the air flow into the combustion chamber. Refer to Symptoms - Engine Mechanical (
See: Engine, Cooling and Exhaust/Engine/Testing and Inspection/Symptom Related Diagnostic Procedures/Symptoms - Engine Mechanical).

Diagnostic Aids
Any loading of the engine that lowers engine RPM, such as with partial application of the clutch, A/C cycling etc., during the first 17 s of engine
run time may set this DTC.
Circuit/System Verification
1. Allow the engine to cool.
2. Start and idle the engine for at least 2 min.
3. DTC P1400 should run and pass.
Circuit/System Testing
* Inspect the air intake system for the following:
- Damage, restriction, or modification
- Dirty or deteriorating air filter element
- Crankcase ventilation system for correct operation-Refer to Crankcase Ventilation System Inspection/Diagnosis (See: Powertrain
Management/Emission Control Systems/Positive Crankcase Ventilation/Testing and Inspection).
- Water intrusion
- Vacuum leak and other un-metered air downstream of the mass air flow (MAF) sensor
- Intake manifold leak
* Inspect the exhaust system for the following:
- Water intrusion
- Exhaust leak
- Damaged, restricted, modified or enhanced exhaust system-Refer to Symptoms - Engine Exhaust (See: Engine, Cooling and
Exhaust/Exhaust System/Testing and Inspection/Symptoms - Engine Exhaust).
* Inspect the engine mechanical for items that could alter the air flow into the combustion chamber. Refer to Symptoms - Engine Mechanical (
See: Engine, Cooling and Exhaust/Engine/Testing and Inspection/Symptom Related Diagnostic Procedures/Symptoms - Engine Mechanical).

Conditions for Setting the DTC
DTC P0300
The ECM is detecting a crankshaft speed change indicating a random misfire is occuring that exceeds mandated emission level standards or is at
catalytic converter damaging levels.
DTC P0301, P0302, P0303, P0304, P0305, P0306, P0307, or P0308
The ECM is detecting a crankshaft speed change indicating a single cylinder misfire is occuring that exceeds mandated emission level standards or
is at catalytic converter damaging levels.
Action Taken When the DTC Sets
* DTCs P0300-P0308 are Type B DTCs.
* When the MIL is flashing the fuel injector may be disabled for the misfiring cylinder to protect the catalytic converter.
* Depending on the conditions that set the DTC, the engine may go into Open Loop.
Conditions for Clearing the MIL/DTC
* DTCs P0300-P0308 are Type B DTCs.
* The DTC must run and pass under the same operating conditions that were present when the DTC failed.
Diagnostic Aids
* Ensure that each fuel injector is connected to the proper fuel injector harness connector.
* A misfire may only occur when the engine is operating under a load or when the engine is cold.
* A high resistance condition on any ignition control (IC) circuit can cause an engine misfire P0300-P0308 DTC to set without setting an IC
circuit P0351-P0358 DTC.
* This test procedure requires that the vehicle battery has passed a load test and is completely charged. Refer to Battery Inspection/Test (See:
Starting and Charging/Testing and Inspection/Component Tests and General Diagnostics/Battery Inspection/Test).
* A misfire DTC could be caused by an excessive vibration from sources other than the engine. Inspect the following for possible sources of
vibration:
- A tire or wheel that is out of round or balance
- Variable thickness brake rotors
- An unbalanced drive shaft
- Certain rough road conditions
- A damaged accessory drive component or belt
- A damaged reluctor wheel
- The Crankshaft Position System Variation Learn procedure may need to be performed.

* This test procedure requires that the vehicle battery has passed a load test and is completely charged. Refer to Battery Inspection/Test (See:
Starting and Charging/Testing and Inspection/Component Tests and General Diagnostics/Battery Inspection/Test).
* A misfire DTC could be caused by an excessive vibration from sources other than the engine. Inspect the following for possible sources of
vibration:
- A tire or wheel that is out of round or balance
- Variable thickness brake rotors
- An unbalanced drive shaft
- Certain rough road conditions
- A damaged accessory drive component or belt
- A damaged reluctor wheel
- The Crankshaft Position System Variation Learn procedure may need to be performed.
