So what does Toyota's "precision cut steel reinforcement bar" actually look like? Judging from the Globe's Wednesday visit to Ernie Boch's Toyota dealership in Norwood, it appears to bear the size and thickness of a postage stamp.

"Something like this here, easiest fix ever," said mechanic Stephen Oranellas. "It's a very small fix for a big problem."

Toyota, which began shipping the metal stamping to dealerships this week, is riding on this little part to fix the 2.3 million cars recalled for sticky throttle pedals. The piece is supposed to reduce "rare occurrences of excessive friction on contact points" in the pedal assembly. The company has not yet decided on a solution for the earlier floor mat entrapment recall (other than sawing part of the gas pedal down) which now affects 5.75 million cars.

But the National Highway Traffic Safety Administration and a committee in the House of Representatives are trying to determine whether Toyota's electronic sensors may also be at fault. Many modern cars use electronic "drive by wire" systems — which negate the mechanical, cable-actuated setup of traditional throttles — to more precisely control the engine's fuel intake and thus increase fuel economy. The same technology can be tuned to provide faster throttle response for performance-oriented cars.

The NHTSA is trying to determine if electromagnetic interference can cause these throttle systems to malfunction. From testing a 2007 Lexus ES 350, the NHTSA said the throttle had "no vulnerabilities" to interference, but that magnetic fields near the throttle body caused engine speed to rise by up to 1,000 rpm, according to The New York Times. The Times said the agency did not have any testing procedures to repeat the claim.

In related news, the NHTSA revealed about 100 complaints, two of them involving crashes that resulted in injuries, regarding brakes on the Prius, which has not been the subject of a recent recall.

Globe staff writers D.C. Denison and Erin Ailworth contributed to this report.
