    TPS and Problems.

    Hey everyone. I am currently working out the final bugs in my F22B DOHC swap. Tonight I tried to calibrate my TPS sensor in, due to my throttle being erratic. I used the multimeter method but all I can get is a straight voltage of 0.641 volts even when I'm moving the sensor back and fourth with the key on. I know the sensor is good because its the one my accord came with and the throttle worked fine, before the swap. And I'm 95&#37; sure I have the black plastic piece and spring installed correctly. Any comments or guidance is greatly appreciated. Thanks

    Arent you supposed to use ohms? I could be wrong......

      The guide I was using said to use voltage which would make sense due the change in voltage at idle to wide open throttle which is how the tps works. But I also tried ohms as well and I'm getting a constant reading with that as well.

        make sure the throttle plate is closed completely...otherwise you might have to make more adjustment in your tps.

          what he said....my throttle plate sticks sometimes. Just make sure your throttle cable is loose enough to let it close fully.

            Just posted this up earlier today on another thread...

            As someone mentioned, you will have to remove the TB from engine. Use a cut-off wheel/dremel to make a slot across both factory screws. Use flat-head 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.

            Set TPS to 0.45V closed.

            - 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.

            See CB7Tuner DIY stickies for base idle & ignition timing procedure.

              Just created another DIY for setting TPS, thanks for the idea.

                Just thought I'd let everybody know, that I finished my F22B DOHC swap. It has been running strong for about week now, with no problems.
