Manufacturer-specific powertrain code — definition not reliably documented; its meaning varies by make, model, and year, so confirm it against your manufacturer's service information
The P1380 code means the vehicle's onboard diagnostic system has detected: Manufacturer-specific powertrain code — definition not reliably documented; its meaning varies by make, model, and year, so confirm it against your manufacturer's service information. This is a low severity code.

Manufacturer-specific code. P1380 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 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 — P1380 is manufacturer-specific and can mean different things across brands.
-
Read P1380 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 P1380 on specific vehicles — tap your vehicle for the fix and the exact part:
2001-2010 Chrysler Town & Country/Dodge Caravan 3.3L/3.8L moderate DIY
Chrysler P1380 = 'Misfire Detected, Rough Road Hardware Missing.' Usually occurs after an ABS module or wheel speed sensor failure. The misfire detection system uses wheel speed inputs to exclude false misfires from rough pavement. Scan for ABS codes -- fix the ABS code(s) and P1380 clears. Most common is a failed front wheel speed sensor.

Jeep P1380 appears alongside ABS DTCs. The PCM and ABS module communicate via CAN; when ABS is faulted, misfire detection is disabled and P1380 sets. Diagnose the ABS side first (usually a wheel speed sensor). Once ABS is fixed and cleared, P1380 goes away on its own within a drive cycle.
Labor: 1-2 hours2002-2008 Dodge Ram 1500 4.7L/5.7L HEMI moderate DIY
Ram P1380 comes with ABS codes, typically U0121 (lost comm with ABS module). Check the CAN bus wiring at the ABS module connector for corrosion, then test the ABS module itself. A failed ABS module on pre-2009 Rams is a known issue -- Module Masters rebuilds them for ~$250 vs $900 new.

Does P1380 mean the same thing on every vehicle?
No. P1380 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 P1380 most likely indicate?
Manufacturer-specific powertrain code — definition not reliably documented; its meaning varies by make, model, and year, so confirm it against your manufacturer's service information. Treat this as a general guide and verify the specifics for your vehicle.
