PINPOINT TEST HD: MISFIRE DETECTION MONITOR
Introduction

NOTE: Mechanical noise caused by the front end accessory drive components, mechanically driven cooling fans, or rough roads at high RPM with light load conditions may produce a non-symmetrical loss of cylinder acceleration, which may result in a misfire.

Normal Operation and Fault Conditions

Refer to the DTC Fault Trigger Conditions.

Clearing the PCM Diagnostic Trouble Codes (DTCs) erases any PCM recorded freeze frame data. Make sure to record any PCM freeze frame information before proceeding.

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
PCM P0300:00 Random Misfire Detected: No Sub Type Information Sets when PCM detects an engine misfire in multiple cylinders or the PCM cannot identify which cylinder is misfiring.
PCM P0301:00 Cylinder 1 Misfire Detected: No Sub Type Information Sets when PCM detects an engine misfire in cylinder 1. Misfire is defined as lack of combustion in a cylinder due to absence of spark, incorrect fuel metering, low compression, or any other cause. The MIL blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded.
PCM P0302:00 Cylinder 2 Misfire Detected: No Sub Type Information Sets when PCM detects an engine misfire in cylinder 2. Misfire is defined as lack of combustion in a cylinder due to absence of spark, incorrect fuel metering, low compression, or any other cause. The MIL blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded.
PCM P0303:00 Cylinder 3 Misfire Detected: No Sub Type Information Sets when PCM detects an engine misfire in cylinder 3. Misfire is defined as lack of combustion in a cylinder due to absence of spark, incorrect fuel metering, low compression, or any other cause. The MIL blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded.
PCM P0304:00 Cylinder 4 Misfire Detected: No Sub Type Information Sets when PCM detects an engine misfire in cylinder 4. Misfire is defined as lack of combustion in a cylinder due to absence of spark, incorrect fuel metering, low compression, or any other cause. The MIL blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded.
PCM P0313:00 Misfire Detected With Low Fuel: No Sub Type Information Sets when PCM detects an engine misfire fault with low fuel level. Verify the fuel level is above 1/8 before diagnosing engine misfire Diagnostic Trouble Codes (DTCs).
PCM P0316:00 Misfire Detected On Startup (First 1000 Revolutions): No Sub Type Information Sets when PCM detects an addition to any type B misfire DTC which occurs in the first 1,000 revolution test interval following engine start. Freeze frame data and the DTC P03xx are also stored, indicating which cylinder the misfire occurred.

DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
PCM P0351:00 Ignition Coil 'A' Primary Control Circuit/Open: No Sub Type Information Sets when the PCM detects an invalid ignition diagnostic monitor pulse signal from the ignition module PCM . The DTC P0351 only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not set DTC P0351. The DTC P0301 does not set for a coil primary circuit malfunction. DTC P0351 may set with or without the DTC P0301, however DTC P0351 sets first. When this DTC is set, the PCM enters failure mode effects management which shuts down the injector for the associated cylinder in order to protect the catalytic converter. This is normal operation, do not attempt to diagnose the injector with this DTC present. When a primary coil is damaged due to a harness short to ground, the PCM is not damaged. Do not replace the PCM without verifying the coil driver functionality. Use a 12 volt non-powered test lamp to verify vehicle power (VPWR) voltage at the ignition coil harness connector.
PCM P0352:00 Ignition Coil 'B' Primary Control Circuit/Open: No Sub Type Information Sets when the PCM detects an invalid ignition diagnostic monitor pulse signal from the ignition module PCM . The DTC P0352 only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not set the DTC P0352. The DTC P0302 does not set for a coil primary circuit malfunction. DTC P0352 may set with or without the DTC P0302, however the DTC P0352 sets first. When this DTC is set, the PCM enters failure mode effects management which shuts down the injector for the associated cylinder in order to protect the catalytic converter. This is normal operation, do not attempt to diagnose the injector with this DTC present. When a primary coil is damaged due to a harness short to ground, the PCM is not damaged. Do not replace the PCM without verifying the coil driver functionality. Use a 12 volt non-powered test lamp to verify vehicle power (VPWR) voltage at the ignition coil harness connector.
PCM P0353:00 Ignition Coil 'C' Primary Control Circuit/Open: No Sub Type Information Sets when the PCM detects an invalid ignition diagnostic monitor pulse signal from the ignition module PCM . The DTC P0353 only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not set the DTC P0353. The DTC P0303 does not set for a coil primary circuit malfunction. DTC P0353 may set with or without the DTC P0303, however the DTC P0353 sets first. When this DTC is set, the PCM enters failure mode effects management which shuts down the injector for the associated cylinder in order to protect the catalytic converter. This is normal operation, do not attempt to diagnose the injector with this DTC present. When a primary coil is damaged due to a harness short to ground, the PCM is not damaged. Do not replace the PCM without verifying the coil driver functionality. Use a 12 volt non-powered test lamp to verify vehicle power (VPWR) voltage at the ignition coil harness connector.
PCM P0354:00 Ignition Coil 'D' Primary Control Circuit/Open: No Sub Type Information Sets when the PCM detects an invalid ignition diagnostic monitor pulse signal from the ignition module PCM . The DTC P0354 only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not set the DTC P0354. The DTC P0304 does not set for a coil primary circuit malfunction. DTC P0354 may set with or without the DTC P0304, however the DTC P0354 sets first. When this DTC is set, the PCM enters failure mode effects management which shuts down the injector for the associated cylinder in order to protect the catalytic converter. This is normal operation, do not attempt to diagnose the injector with this DTC present. When a primary coil is damaged due to a harness short to ground, the PCM is not damaged. Do not replace the PCM without verifying the coil driver functionality. Use a 12 volt non-powered test lamp to verify vehicle power (VPWR) voltage at the ignition coil harness connector.
PCM P06D1:00 Internal Control Module Ignition Coil Control Module Performance: No Sub Type Information Sets when the PCM detects an error with the ignition coil driver and diagnostic circuit. Check for other Diagnostic Trouble Codes (DTCs) and diagnose those first. Check for aftermarket performance products. If an updated calibration is available, update the calibration to the latest level. If an updated calibration is not available, clear the Diagnostic Trouble Codes (DTCs) and repeat the self-test.
