How to Test Throttle Position Sensor (TPS) on Honda Civic, CRX, Integra etc

Here's how to test if the throttle position sensor (T) on your Honda is operating correctly. This will work for most 90s Hondas including Civic, Integra, CRX, Shuttle etc that have D15, D16, B16 etc engines.

You will need a multimeter to test voltage.

With the key in the "ON" position (engine not running), you need to put the + probe of the multimeter on the red wire on the T plug (middle wire), and the - probe on the negative battery terminal, or other ground spot.

The multimeter should read close to 0.5v with the throttle closed, and 4.5v with the T at wide open throttle (WOT).

Also test to make sure the voltage climbs and drops smoothly as you open and close the throttle.

If any of this is not happening, you will either need to adjust the T by loosening the bolts and shifting it's position until the readings match the numbers above, or replace the T.
