P0219 Engine Overspeed Condition

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

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.

Likely causes

Downshift at too high a road speed (manual gearbox)
Descending in too low a gear
Fault in the speed signal (crankshaft sensor, wiring)
Diesel runaway (oil drawn into the intake) or sticking injection

Symptoms

  • Usually no lasting symptoms, only a stored code
  • Briefly very high revs, limiter intervening
  • Check engine light possible (manufacturer-dependent)
  • After real overspeed: rattling, loss of power

Repair estimate

DifficultyEasyDIY possible
Parts and labour€0–150
Time0.2–1 h

Typical range across vehicles; the real cost depends on what the testing finds.

What to check first

  1. Review recent driving
  2. Check clutch condition
  3. On diesels, check for oil entering the intake
