1.
Disconnect throttle sensor connector.
2.
Using an ohm meter, check resistance across terminals e and f.
Resistance value should change smoothly, without any glitches, from approximately 1 to approximately 9 ohms as the throttle is moved from idle
to WOT.
Replace sensor if it fails the above test.
