Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Pinpoint Test Hd: Misfire Detection Monitor
2021 Ford Edge SE, 4WDSECTION Pinpoint Test Hd: Misfire Detection Monitor
WARNING: This page is about a different variant/trim than selected.
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 P0305:00 | Cylinder 5 Misfire Detected: No Sub Type Information | Sets when PCM detects an engine misfire in cylinder 5. 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 P0306:00 | Cylinder 6 Misfire Detected: No Sub Type Information | Sets when PCM detects an engine misfire in cylinder 6. 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. |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
