* 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.

Circuit/System Description
The throttle body assembly contains 2 throttle position (TP) sensors. The TP sensors are mounted to the throttle body assembly and are not
serviceable. The TP sensors provide a signal voltage that changes relative to throttle blade angle. The engine control module (ECM) supplies the TP
sensors with a common 5-volt reference circuit, a common low reference circuit, and 2 independent signal circuits.

瀚慖f a DTC P0121, P0122, P0123, P0221, P0222, or P0223 set while performing this procedure, refer to DTC P0121-P0123 or
P0221-P0223 (Without LF1, LFW) (See: P Code Charts/P0121) for further diagnosis.
5. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
1. Inspect the Q38 throttle body for the following conditions:
* A throttle blade that is not in the rest position
* A throttle valve that is binding open or closed
* A throttle valve that opens or closes without spring pressure
瀚慖f a condition is found, replace the Q38 throttle body.
Note: Disconnecting the throttle body harness connector causes additional DTCs to set.
2. Ignition OFF, disconnect the harness connector of the Q38 throttle body.
3. Ignition ON, test for 4.0-4.2 V between the TAC motor control 1 circuit terminal B and ground.
瀚慖f voltage is greater than the specified range, test each of the motor control circuits for a short to voltage. If the circuits tests normal,
replace the K20 Engine Control Module.
瀚慖f voltage is less than the specified range, test the motor control 1 circuit for a short to ground or an open/high resistance. If the circuit
tests normal, replace the K20 Engine Control Module.
4. Connect a test lamp between the TAC motor control 2 circuit terminal A and B+. The test lamp should NOT illuminate.
瀚慖f the test lamp illuminates, test the control circuit for a short to ground. If the circuit tests normal, replace the K20 Engine Control
Module.
5. Test for greater than 3.5 V between TAC motor control 1 circuit terminal B and TAC motor control 2 circuit terminal A.
瀚慖f the voltage is less than the specified value, test the motor control 2 circuit for an open/high resistance. If the circuit tests normal,
replace the K20 Engine Control Module.
6. Ignition OFF, connect the EL 34730-405 - Injector Test Lamp between the TAC motor control 1 circuit terminal B and TAC motor control 2
circuit terminal A of the throttle body harness connector. Observe the injector test lamp while turning the ignition ON for 5 s and then OFF.
Verify the injector test lamp illuminates brightly and then turns OFF.
瀚慖f the injector test lamp does not illuminate, replace the K20 Engine Control Module.
7. If all circuits test normal, replace the Q38 throttle body.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

Conditions for Clearing the MIL/DTC
DTCs P2178, P2180, P2188, and P2190 are Type B DTCs.
Diagnostic Aids
* An HO2S will not cause this DTC to set without the occurrence of circuit related HO2S DTCs. Do not replace an HO2S to address this DTC.
* Observing the LT FT Bn 1 and Bn 2 parameters, while driving the vehicle can determine whether the rich condition is effecting only one
bank , or is common to both banks of the engine.
* A fuel system delivery condition causes this DTC to set. Thoroughly inspect all items that cause a rich condition. Refer to Fuel System
Diagnosis (See: Powertrain Management/Computers and Control Systems/Testing and Inspection/Component Tests and General
Diagnostics/Fuel System Diagnosis).
* Review the Freeze Frame/Failure Records with a scan tool.

* 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.

Circuit/System Description
The throttle body assembly contains 2 throttle position sensors. The TP sensors are mounted to the throttle body assembly and are not serviceable.
The TP sensors provide a signal voltage that changes relative to throttle blade angle. The Engine Control Module (ECM) supplies the TP sensors
with a common 5 V reference circuit , a common low reference circuit, and two independent signal circuits. The TP sensors have opposite
functionality. TP sensor 1 signal voltage decreases from greater than 4 V at idle to less than 1 V at wide open throttle (WOT). TP sensor 2 signal
voltage increases from less than 1 V at idle to greater than 4 V at WOT.
