  1. Measure voltage between YELLOW/WHITE (+) terminal and GREEN/WHITE (-) terminal. Voltage should read approx 5.0 volts . If not, measure voltage between YELLOW/WHITE (+) terminal and chassis ground;
    • If 5.0 volts is measured check for open in GREEN/WHITE (-) wire between Programmed Fuel Injection Electronic Control Module (PGM-FI ECM) D22 and TPS connector.
    • If 5.0 volts is not measured, Turn ignition switch off, install test harness between PGM-FI ECM and harness connector, turn ignition on. measure voltage between terminal D20 (+) and D22 (-), if 5.0 volts is measured, inspect for open in YELLOW/WHITE wire between D20 and TPS connector. If 5.0 volts is not measured, substitute known good PGM-FI ECM and retest.
  1. Turn ignition switch off. Reconnect the three pin connector at the TPS. Install the test harness between the PGM-FI ECM and the harness connector. Turn ignition switch on.
  2. Measure voltage between terminal D11 (+) and terminal D22 (-). Voltage should read approx. 0.5 volts at closed throttle position and approx. 4.5 volts at full throttle position with a smooth transition in between. If not, replace TPS with known good part and retest.

Now you will be able to test it if you want.

Are you sucking in water into the throllle body?
Customer: replied 9 years ago.
i belive that at one point water was suck into the TB.
You might want to clean your throttle body also at the same time,and move the intake for the air filter higher.
