Misfire Detected on Startup First 1000 Revolutions
P0316 means Misfire Detected on Startup First 1000 Revolutions. Learn the likely symptoms, common causes, and a safe diagnostic order before replacing parts.
What you may notice
Symptoms
- 01Check Engine light
- 02Rough running, hesitation, or reduced power
- 03Hard starting or unstable idle
- 04Possible increase in fuel use
Where to look first
Common causes
- 01Wiring, connector, power, or ground fault
- 02Faulty actuator, ignition component, or position input
- 03Oil-flow, timing, boost, or mechanical problem
- 04Control-module calibration or internal fault
A sensible sequence
Best diagnostic order
- 01Save every stored and pending code plus freeze-frame data
- 02Check service information for the exact engine and code-setting conditions
- 03Inspect power, ground, wiring, connectors, hoses, and fluid condition
- 04Use scan data and circuit tests to separate an electrical fault from a mechanical one
- 05Repair the verified cause, clear the code, and repeat the enabling drive cycle
Step by step
What to check and repair
- 01Inspect connectors, wiring, grounds, and related fuses
- 02Compare commanded and actual values with a capable scan tool
- 03Test the affected actuator or sensor before replacing it
- 04Check mechanical timing, oil condition, compression, or boost control when relevant

Live-data clues
Commanded vs actual position
- Typical behavior
- Values should follow each other under the specified test conditions
- Possible clue
- A large or intermittent difference can indicate control, wiring, oil-flow, or mechanical trouble
Misfire, timing, or load data
- Typical behavior
- Behavior should remain stable for the operating condition
- Possible clue
- A repeatable change helps identify the affected cylinder or operating range
| Parameter | Typical behavior | What it can suggest |
|---|---|---|
| Commanded vs actual position | Values should follow each other under the specified test conditions | A large or intermittent difference can indicate control, wiring, oil-flow, or mechanical trouble |
| Misfire, timing, or load data | Behavior should remain stable for the operating condition | A repeatable change helps identify the affected cylinder or operating range |
What P0316 means
P0316 is a generic powertrain diagnostic trouble code defined as “Misfire Detected on Startup First 1000 Revolutions.” The vehicle control module stored it after the monitored circuit or system failed its expected test. The code identifies the area and failure type; it does not by itself prove that one named component must be replaced.
Diagnostic direction
Engine codes need both electrical and mechanical checks. A circuit code can be caused by wiring, while a performance or correlation code may require oil-pressure, timing, compression, ignition, or airflow testing.
Before clearing the code
Save stored, pending, and permanent codes plus freeze-frame data. Note the operating condition that set the code, inspect related connectors and wiring, and check vehicle-specific service information. After a verified repair, clear the code only when appropriate and repeat the enabling conditions to confirm that it does not return.
