P0219Engine Overspeed Condition
- Generic OBD-II code · Powertrain
- How the car detects it
- P0219 is a condition code: engine speed has exceeded the overspeed limit even though the rev limiter already cuts fuel – so the engine was driven from outside, usually by downshifting at too high a road speed or descending in too low a gear, or the speed signal was wrong. Limits: Ford 6.7 litre diesel above 4,200 rpm, 3.0 litre above 4,800 rpm, after 0.1 s; GM/Saab 2.8 V6 petrol with manual gearbox above 7,000 rpm for 1 s; Saab 2.2 diesel above 6,200 rpm, although fuel is cut from 5,000 rpm. Many manufacturers store it without the warning light. Saab advises: together with a camshaft sensor code it was real overspeed, alone check the speed signal; after real overspeed inspect the engine for valve train damage.
