You can't effectivly check for voltage outputs...all the sensors connect to the computer and you are liable to cause more damage than good. Most problems with one of these will give a fault code. However if you want to check the TPS I have included ops check and adjustment. What makes you think you have a problem with one of these?
The checkout and adjustment proceedures for the TPS are:
1. Disconnect plug from TPS and connect a digital ohm meter between terminals A and B of the sensor.
2. Turn the throttle lever to the Wide OPEN Throttle (WOT) position and check the resistance reading on the multimeter. The reading should be approximately 5K ohms.
3. Turn the throttle lever to the fully CLOSED position and check the reading on the multimeter. The reading should be below 1 ohm.
4. If the resistances are not within the specifications, adjust the TP sensor as follows:
- Loosen, but do not remove, the TP sensor screws.
- With the throttle lever in the closed position, adjust the TP sensor until the multimeter reads below 1 ohm.
- Turn the throttle lever to the WOT position and check the resistance. The resistance should be approximately 5K ohms. If the TP sensor cannot be adjusted to specification, the throttle body must be replaced.
5. After the TP sensor resistance readings are to specification, tighten the TP sensor screws to 1.6-2.3 Nm (14.2-20.3 lb in) .
Connect the TP sensor electrical connector.
