Manufacturer-specific hybrid / high-voltage code — definition not reliably documented; verify against your make's service information
The P3182 code means the vehicle's onboard diagnostic system has detected: Manufacturer-specific hybrid / high-voltage code — definition not reliably documented; verify against your make's service information. This is a critical severity code.

Manufacturer-specific code. P3182 is a manufacturer-specific DTC, so its exact definition can differ by make, model, and year. Use the meaning above as a general guide, and always confirm it against your vehicle manufacturer's official service information (or a make-specific scan tool) before diagnosing or replacing parts.
Common Misconceptions / Fact Check
-
Commonly claimedMany databases show P3182 as 'Hybrid System Emergency Shutdown Activated.'
VerifiedNo authoritative source supports that wording. P3182 is manufacturer-specific; the one documented meaning (Nissan Leaf) is a high-voltage battery system fault. Confirm the exact definition for your make before diagnosing.

Common Symptoms
- Check Engine or a related warning light on
- Exact symptoms depend on the specific system this code covers for your make
- A make-specific scan reveals which subsystem and circuit is involved
Probable Causes (Ranked by Likelihood)
- A fault in the specific component or circuit this code monitors (the exact part varies by manufacturer) High
- Damaged wiring, a corroded connector, or a poor ground in that circuit Moderate
- A related sensor or control module reporting or causing the fault Moderate
Step-by-Step Diagnostic Procedure
-
Confirm your exact make, model, and year first — P3182 is manufacturer-specific and can mean different things across brands.
-
Read P3182 with an enhanced/make-specific scan tool and check your manufacturer's official service information for the precise definition and procedure.
-
Inspect the wiring, connectors, and grounds for the indicated circuit before replacing any part.
Common Fixes by Vehicle
What techs usually find when diagnosing P3182 on specific vehicles — tap your vehicle for the fix and the exact part:
2013-2018 Nissan Altima 2.5L CVT Moderate DIY
P3182 on Nissan CVT vehicles typically indicates a fuel delivery problem that can mimic CVT symptoms. Start with a fuel pressure test at the rail -- should be 51 psi key-on. Check for a failing low-pressure fuel pump in the tank; Nissan TSB NTB14-056 covers this failure pattern. Don't replace the CVT until fuel system is verified.

On these CVT-equipped Nissans, P3182 often pairs with transmission slip codes. Update the TCM firmware first (many free updates from Nissan dealers under extended warranty). If the fluid is burnt, a CVT flush with Nissan NS-3 fluid is required -- never use aftermarket CVT fluid in these units.
Labor: Diagnostic only2015-2019 Nissan Sentra 1.8L Moderate DIY
The Sentra's fuel injection system triggers P3182 when the fuel pressure sensor or HPFP fails. Scan for associated codes (P0087 is common). The high-pressure fuel pump on direct-injection Sentras is a known weak point; replacement runs about $400 for the part. Check the cam follower for wear while replacing.
Labor: 1-2 hoursFrequently Asked Questions
Does P3182 mean the same thing on every vehicle?
No. P3182 is a manufacturer-specific diagnostic trouble code, so its exact meaning varies by make, model, and year. Always confirm it against your vehicle manufacturer's service information before diagnosing or replacing parts.
What does P3182 most likely indicate?
Manufacturer-specific hybrid / high-voltage code — definition not reliably documented; verify against your make's service information. Treat this as a general guide and verify the specifics for your vehicle.
