OBD-II Code
P1316
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$80–$2,200
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
$80 (single coil + plug DIY) to $2200 (full coil set + plugs + replacement catalytic converter after substrate damage).
P1316 on a Volvo is Catalyst Damaging Misfire — the ECM's misfire-counter algorithm has accumulated enough misfire events on one or more cylinders that, if driving continues, raw fuel will reach the catalyst hot enough to melt the substrate.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P1316 on a Volvo is Catalyst Damaging Misfire — the ECM's misfire-counter algorithm has accumulated enough misfire events on one or more cylinders that, if driving continues, raw fuel will reach the catalyst hot enough to melt the substrate. The Volvo threshold is roughly >50 misfire events per 1000 revolutions on a single cylinder, or >200 events per 1000 revs distributed across multiple cylinders, before P1316 latches and the CEL flashes.
Cheapest-first ladder
- Read the freeze-frame data — Volvo stores per-cylinder misfire counters under Mode $06, and the cylinder with the highest count is your starting point.
- On 5-cyl whiteblock cars, pull the coil-on-plug from the offending cylinder, inspect the plug (oil-wet, fuel-wet, carbon-fouled, or normal-dead) and swap that coil with an adjacent cylinder; clear codes and confirm whether the misfire follows the coil.
- If the misfire stays put after a coil/plug swap, run a compression test (whiteblock cylinders should land 175-210 psi cranking, within 15% of each other) and an injector-balance test.
- Critical: a flashing CEL with P1316 means STOP driving — the cat is being damaged in real time. Do NOT just clear the code and drive home; Volvo OEM cats on whiteblock T5 cars run $700-$1400 plus labor, and a melted substrate inside a 'still passes visual' housing will throw P0420 the moment the misfire is fixed, doubling the repair cost. The classic misdiagnosis is replacing the coil pack that fixes the misfire and stopping there, only to have the customer return three weeks later with P0420 from the now-cooked cat.

- 1999-2007Volvo S60/S80/V70/XC90 2.5T (B5234T/B5254T 5-cyl) throws P1316 most commonly from a single failed COP coil — Volvo's OEM coils have a well-known 80K-120K mi failure curve and the smart play is replacing all five at once since the others are typically 70-80% of the way to failure.
- 2004-2007Volvo S60R/V70R sees P1316 from the same coil pattern but more aggressively because the higher cylinder pressures stress the spark gap harder.
- 2008-2016Volvo XC60 / S60 T5/T6 (B6304T) throws P1316 from coil failures and from injector-deposit issues on the early direct-injection variants.
- 2010-2018Volvo V70 D5 diesel does not throw P1316 (diesel misfire logic uses different codes) but the platform's TF-80SC transmission can manifest a vibration that mimics a misfire.
