Washington ? Toyota Motor Corp. plans to start sending parts to dealers in the coming days to fix a sticky gas pedal problem that has tarnished its image and led to the recall of 4.2 million cars and trucks on three continents, according to people briefed on the matter.

Toyota plans to reveal details of the fix on Monday morning, according to two dealers who asked not to be identified because the plan had not been announced. One dealer was told by a Toyota executive that the parts could arrive Thursday or Friday.

The automaker told the dealers about the plan Saturday after hearing from the National Highway Traffic Safety Administration that it did not object to the fix, the dealers said. A Department of Transportation official, who also requested anonymity because the announcement had not been made, confirmed that the government had no objections.
