P00xx codes: fuel & air metering — valve timing, O2-sensor heaters, boost control, fuel pressure
194 codes in this range, all generic — the same meaning on every make. Codes in these ranges cover the parts that decide how much air and fuel reach the engine and how the exhaust is treated on the way out: variable valve timing, oxygen-sensor heaters, turbo boost control, the electronic throttle and accelerator pedal, intake runners, NOx sensors and — on diesels — the particulate filter and the AdBlue (SCR) system.
What usually causes codes in this area
- Wiring and connectors — most codes here are electrical (“circuit”, “low”, “high”)
- A failed sensor or actuator
- Dirt and carbon: sticking throttles, EGR valves and intake runners
- Engine oil that is low or old, which variable valve timing depends on
Can you keep driving?
Most codes here leave the car drivable, sometimes with reduced power. Codes that put the engine into limp mode (throttle, boost control) and diesel exhaust-treatment codes deserve a prompt repair — on many diesels an AdBlue fault ends in a countdown after which the engine won’t restart.
