Throttle Position Switch (V6 Engines)

Disconnect idle switch. Connect ohmmeter between center and outer terminals. Check idle switch off/on speed, while closing throttle valve. Idle switch should turn on at 100-400 RPM (800-1100 RPM on Maxima & 300ZX). If idle switch does not perform as indicated, loosen idle switch hold-down screws and rotate switch body to set off/on speed to specification.
