ENG: Setting TPS

[HondaFan81]

Setting the TPS (throttle position sensor) implies you have made it adjustable from factory preset condition.

TO MAKE TPS ADJUSTABLE:

- Remove the TB from engine.
- Use a cut-off wheel/dremel to make a slot across both factory screws.
- Use flat-head screwdriver to remove.
- Buy 2 screws from hardware store to replace, reinstall TPS with news screws only finger tight.
- Reinstall TB onto engine and connect electrically.

SETTING TPS:

- You will set TPS to 0.45V at TB throttle closed position.
- TPS needs to be electrically connected.
- Turn key to ignition "II" position.
- Multimeter red probe (backprobe) into red w/blk strip wire at driver-side upper shock mount connector.
- Multimeter black probe on negative battery terminal.
- Multimeter set to voltage (you'll be measuring 5V max).
- With probes set, multimeter should read somewhere 0-5V.
- Loosen TPS screws, rotate until 0.45V and snug screws.
- Move onto setting base idle, then base ignition timing.

FYI, the screws that hold the bracket on the automatic TB's for the other throttle cable fit PERFECTLY for replacing the rivets on the TPS, as do the 2 larger screws holding the spring assembly onto the IAB plate on a6 and h23 IM's

Hello,
Could you give the exact size of the 2 screws? I only have one car and cannot take the screws to the store to size fit while the TPS is off.

Thanks.
