OBD-II Code
P0364
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–$1,500+
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
$80 (single coil + extended labor on a Triton V10) to $1,500+ (specialty diesel glow plug harness on an industrial engine).
P0364 is a reserved generic-OBD code in the SAE J2012 misfire-detection range that some manufacturers use for cylinder 11 misfire on V10 and large-displacement diesel applications, while others leave it unused or use it for misfire-detection circuit faults.
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.

P0364 is a reserved generic-OBD code in the SAE J2012 misfire-detection range that some manufacturers use for cylinder 11 misfire on V10 and large-displacement diesel applications, while others leave it unused or use it for misfire-detection circuit faults. The code is rarely seen in general repair because it only exists in active form on engines with 11 or more cylinders — primarily the Dodge/Ram 8.3L Viper V10, the Ford 6.8L Triton V10, the VW W12, and certain large-displacement diesel V10/V12s with cylinder-specific glow plug detection circuits that overlap into the misfire range.
Cheapest-first ladder for the V10 misfire interpretation
- Verify the OEM's actual code definition before spending any time — Ford 6.8L V10 uses P0311 for cylinder 11 misfire on most calibrations, while some aftermarket scanners mis-translate the code.
- If genuine cylinder-11 misfire, apply the standard misfire flow (plug read, coil swap to an adjacent cylinder on the same bank, plug swap, compression test).
- If the manufacturer uses P0364 for a glow plug circuit fault on cyl 11, check the glow plug resistance (typically 0.5-2.0 ohms at room temp) and the GPCM's per-cylinder driver output. Target thresholds: misfire counts <50/1000 rev normal, glow plug resistance 0.5-2.0 ohms cold. Expensive-misdiagnosis caveat: because this code is reserved and OEM usage varies, a generic code-definition lookup will steer the wrong way half the time — always pull the OEM-specific service information for the exact VIN before quoting any repair, or you'll spend an afternoon chasing a misfire on an engine that doesn't have an 11th cylinder.

- 1999-2005Ford E-350/F-250/F-350/Excursion with the 6.8L Triton V10 is the primary platform where P0364 might appear in shop work — usually as a misread of P0311 (cyl 11 misfire) by an older scan tool; cyl 11 on this engine is the rear-most cylinder on the right bank and suffers the same coil-boot carbon tracking and stuck-plug issues as the 5.4L 3V Triton family.
- 2003-2006Dodge Viper with the 8.3L V10 throws P0364 from cylinder-specific coil-pack failures; the COP coils are sourced uniquely and run $200+ each. Large-displacement industrial diesels (Detroit Diesel, MTU, Mercedes OM621-family) occasionally use P0364 for glow plug 11 circuit faults — these are rare in light-duty repair shops and almost always come into specialty diesel shops. VW W12 (Phaeton, Bentley Continental) uses different code ranges and won't show P0364.
