OVERALL FUNCTION CHECK
Instead of performing the DTC Detecting Condition, the following method can be used for checking the function of the throttle position sensor. (The "NG" of this check means the same as the DTC detection.)
1. Turn ignition switch "ON".




2. Check the voltage between Engine Control Module (ECM) terminal 23 and 43 (ground) and make sure the followings:
- The voltage when accelerator pedal fully released is approximately 0.3-0.7 volts.




- The voltage rise is linear in response to accelerator pedal depression.
- The voltage when accelerator pedal fully depressed is approximately 4 volts.
