Question about Buick LeSabre
Do you know where the air filter is? It's in a large plastic box underhood, with a (likely) black plastic tube 3-4" in diameter coming out of it and leading to the engine. Where that tube meets the engine is the throttle body. On the side of the throttle body you should see a small box with a harness plugged into it. That will be the throttle position sensor.

Throttle Position Sensor (TPS) signal too low TPS
Check the connections at the TPS sensor located on the trottle body Its located on the trottel body on the opposite side of the accelrator cable linkages. Usually this code means TPS needs replaced.
