Service Brakes

| Code | What it means |
|---|---|
| P0420 | Catalyst efficiency below threshold (bank 1) Often a worn catalytic converter, but failing oxygen sensors or exhaust leaks can set it too. Can cause an emissions test failure. |
| P0300 | Random or multiple cylinder misfire Worn spark plugs, failing ignition coils, fuel or vacuum problems. Do not ignore a flashing check engine light. |
| P0171 | System too lean (bank 1) Often a vacuum leak, dirty MAF sensor, weak fuel delivery or a failing oxygen sensor. |
| P0455 | EVAP system large leak Missing or loose gas cap, or a disconnected or cracked vapor hose. |

Keeping a GMC Savana Passenger 3500 12 Passenger Reliable in Phoenix
Arizona heat is the hardest test a GMC will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a Savana Passenger 3500 12 Passenger that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for Savana Passenger 3500 12 Passenger owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used GMC Savana Passenger 3500 12 Passenger, a pre-purchase inspection shows what the paperwork does not.
