TPS Adjustment

NOTE: Ensure basic idle speed is set to specification before adjusting TPS. See BASIC IDLE SPEED  under IDLE SPEED & MIXTURE. Perform all adjustments with engine at normal operating temperature, front wheels in straight-ahead position, cooling fan and all accessories off, and transmission in Park or Neutral.
  1. Bring engine to normal operating temperature. On Precis, connect Digital Volt-Ohmmeter (DVOM) between throttle position sensor terminals No. 1 (Black wire) and 3 (Light Green wire), and between terminals No. 2 (Green/White wire) and 4 (Green/Black wire) on all others. Turn ignition on. DO NOT  start engine. Note TPS output voltage. Output voltage should be .48-.52 volt.
  2. If output voltage is not correct, loosen TPS mounting screws and rotate TPS until output voltage is within specification. Tighten TPS mounting screws. Turn ignition off. Disconnect negative battery cable for at least 15 seconds to clear diagnostic trouble code. Reconnect negative battery cable.
