- All OBD-II vehicles (any make or model)
- Est. repair cost
- $40 – $800
- Time to fix
- 30 minutes – 2 hours
What it means
Causes include worn plugs/coils, fuel-delivery issues, low compression, or VVT/timing faults. P0316 is a generic OBD-II powertrain code defined in the SAE J2012 standard, so it applies to virtually any 1996-or-newer petrol car or light truck regardless of make. Fix the underlying fault, then clear the code with an OBD-II scan tool — it will return if the problem isn't resolved.
Symptoms
- Check engine light (may flash on start)
- Rough or stumbling cold start
- Hesitation until warm
How to fix it
- 1
Check ignition and fuel
1. Inspect spark plugs and coils. 2. Check fuel delivery and injectors.
- 2
Look at timing/compression
1. If ignition/fuel are good, check VVT operation and compression. 2. Repair, then clear the code.
Frequently asked questions
Why only on startup with P0316?
Cold-start misfires often come from weak spark, cold-fuelling, or oil-related VVT lag that clears once the engine warms. Start with plugs, coils, and oil.
