P1486: EVAP System Blockage Detected (Chrysler)

Severity: low

What it means: P1486 is a Chrysler code meaning the evaporative emission (EVAP) system found a blocked or pinched hose. The EVAP system stores fuel vapor in a charcoal canister. If it's blocked, the fuel tank can't vent properly.

Safe to drive? Usually safe to drive short-term, but a blocked system can cause rough idle or stalling on some cars. Get it checked.

Answers that mention P1486

DIY or shop?

DIY for inspecting hoses. Canister replacement is DIY-able on some cars but often a shop job.

Before you replace parts

  1. Stop topping off the tank after the pump clicks off.
  2. Inspect EVAP hoses for kinks or pinches.
  3. Read all stored codes.
  4. Have the canister and valves tested before replacing them.

Safety / mechanic note

Verify with a mechanic. A blocked EVAP system can cause stalling on some cars. A code points to a circuit or system, not always a specific part.
