Monitor Description
Deposit on the throttle valve increases ISC flow and may cause conditions including engine stall and rough idling. To prevent this, the ISC flow required for idling is maintained by using the ISC learning value and feedback to the engine control computer. When the ISC learning value reaches the limit, the ECM records this DTC.
