P0316 – Meaning, Causes, Symptoms, & Fixes
Code P0316 Definition
Engine Misfire Detected on Startup (First 1000 Revolutions)
What Does Code P0316 Mean?
Code P0316 is triggered when your Engine Control Module (ECM) detects that the position of either your vehicle’s crankshaft or camshaft is outside of its parameters, which can lead to an engine misfire upon starting. The ECM uses information relating to the crankshaft position, the camshaft position, and RPM of the engine to determine ignition timing and fuel delivery. If any on these are outside of their designated parameters, the engine will misfire.
There are several other codes that typically go along with code P0316, and it is important that you clear these first before confronting the main issue. These codes include: P0300, P0301, P0302, P0303, P0304, P0305, P0305, P0306, P0307, P0308, P0309, P0310, P0311, P0312.
What Are the Symptoms of Code P0316?
- Check Engine Light
- Poor Idle
- Rough Engine Start
- Poor Fuel Economy
- Poor Engine Performance
What Causes Code P0316?
- Faulty Ignition System Components
- Faulty Ignition Coil
- Faulty Fuel Injector
- Lack of * Proper * Fuel
- Faulty Crankshaft or Camshaft Position Sensors
- Damaged or Frayed Crankshaft Position Sensor Wires
- Engine Vacuum Leaks
How Serious Is Code P0316?- Severe
Code P0316 is severe because it can affect your vehicle’s ability to start, along with affecting your vehicle’s ability to operate safely. If your car is experiencing Code P0316, it is imperative that you confront the problem as soon as possible.

P0316 Diagnosis and Repair:
- Tools Needed to Diagnose:
Difficulty of Diagnosis and Repair
- Check to see if there are any other codes along with P0316 and clear your Check Engine Light with FIXD. If other codes are present, it is important to address those first, clear the codes, and re-scan to see if Code P0316 still comes up.
- Check the freeze frame data in order to pinpoint the issue.
- Conduct a visual inspection of wiring around the crankshaft and camshaft position sensors for possible wire fraying or disconnection.
- Make sure that you do not have low levels. Make sure that the fuel you are using is of good quality.
- Check to see if the catalytic converter is clogged or if the fuel injector is faulty. If the fuel injector or ignition coils are faulty, consider replacing them.
- Check that the EGR valve is functioning properly.
- Check if there is a specific cylinder that is misfiring, and if so, fix it.
- If Code P0316 is still present, consider replacing the crankshaft or camshaft position sensors.
