P06E9Engine Starter Performance

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
How the car detects it
On cars with stop-start or keyless start the engine module operates the starter relay itself and watches the start: if cranking is commanded but the engine does not turn, turns too slowly or the start is aborted, it sets P06E9. CARB counts an engine start from 150 rpm below warm idle. Thresholds for speed and time are not published. Bulletins show both sides: VW traces P06E9 on the Tiguan to dirt inside the starter that opens its contacts intermittently, and on the Atlas has relays, battery and voltage drop checked; Audi's SQ5 and FCA's Jeep Compass need module software instead. Ford lists P06E9 among the starter faults that disable stop-start.
