GMC C6500 Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the C6500, so we do not have a model-specific ranking to show. These are the check engine codes we see most often on vehicles in Phoenix heat, and any of them can show up on a GMC.
| 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. |
| P0128 | Coolant temperature below thermostat regulating temperature Usually a thermostat stuck open. Fix it to restore efficiency and cabin heat. |
| P0442 | EVAP system small leak Loose or worn gas cap, cracked hose or purge or vent valve. |
| P0301 | Cylinder 1 misfire Commonly a bad spark plug or ignition coil on that cylinder. |
| P0401 | EGR flow insufficient Clogged EGR passages or a stuck EGR valve. |

NHTSA lists 1 recall campaign for the C6500 in these model years, most often involving equipment adaptive/mobility. Recalls are repaired by the manufacturer at no charge to you, but each applies only to certain vehicles. Look up your VIN at nhtsa.gov/recalls.
- 2015 recall, Equipment Adaptive/Mobility (campaign 15V112000): Farber Specialty Vehicles (Farber) is recalling various specialty vehicles modified by Farber and equipped with model S2005, S2010, S5005, S5010, S5505, and S5510 wheelchair lifts manufactured by Ricon Corporation.
Keeping a GMC C6500 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 C6500 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 C6500 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 C6500, a pre-purchase inspection shows what the paperwork does not.
