All Other Models

  1. Disconnect TP sensor connector. Using jumper wires, connect an external ohmmeter between TP sensor terminals No. 1 and 2 on Diamante, or No. 3 and 4 on all other models. See Figure. On Diamante, insert .118" (3.00 mm) feeler gauge between fixed speed adjusting screw and throttle lever. On Mirage 1.8L with cruise control, insert .055" (1.40 mm) feeler gauge between fixed speed adjusting screw and throttle lever. On 3000GT, insert .025" (.65 mm) feeler gauge between fixed speed adjusting screw and throttle lever. On all other models, insert .018" (.45 mm) feeler gauge between fixed speed adjusting screw and throttle lever.
  2. Loosen TP sensor mounting screws and rotate TP sensor fully counterclockwise. Ensure there is continuity between terminals No. 1 and 2 on Diamante, or No. 3 and 4 on all other models. Rotate TP sensor clockwise until there is no continuity and tighten screws. Install Test Harness (MB991348) between TP sensor and harness connector.
  3. Turn ignition on. Using external voltmeter, measure TP sensor output voltage between terminals No. 2 and 4. If voltage is not .4-1.0 volt, check harness and sensor. See DTC P0120 in appropriate SELF-DIAGNOSTICS article.
