CivicTec

I drive a '99 civic vtec B16a6.
Will post pics later...
My engine light is on, i check the ecu code and i get 7 which is tps sensor, i bought a new sensor, fitted it... management light still on.....I took off the battery terminal for a few hours, checked the wires for any breaks and all checks out fine.
Anybody have an idea or suggestion to what i can check or what could be causing the problem?

a tps has to be calibrated.

CivicTec

any guides on how to?

TPS usually doesnt need to be calibrated on Honda's. Its possible that a wire is broken or frayed. Get a multimeter and check for continuity.

CivicTec

I have done that already and there is continuity...oh if I turn the car off while driving and quickly back on the vtec works...

Jimster480

If there is continunity in all the wires then it should be fine. But what about voltage? IS it getting the right amount of volts?

If you took your throttlebody apart for any reason...say to clean it. When you take your "butterfly" out you must make sure it goes back in the same position as it was before. I have done this before and just had to to figure out which position the rotor and butterfly were in before screwing on the TPS.....hope I help.

CivicTec

I did actually take it off to clean it.... I cant remember though in which position the butterfly was though...

TurboTron

remove throttlebody from intake, remove butterfly, remove the TPS from trottlebody (carefully) the spring in there is easy to pop off. Undo the throttlerotor. All you gotta do is wind the rotor back until you feel that it's at the correct starting point, tighten the rotor back on so the assembly stays, now your TPS should already have the little arm where it needs to be, just wiggle it into it's spot. I really wish I could be there to show you....I hope I described this okay...It's a bitch, I've been through this.

Thanks for bumping my 9 year old post only to provide the wrong information and contribute a spelling mistake.

When replacing the TPS sensor, the closed throttle voltage HAS to be set at .490-.500 volts... then open the throttle blade fully and make sure that the TPS voltage doesn't exceed 4.60 volts. Why would the bolt holes in the TPS sensor be slotted/elongated if the sensor itself didn't have to be adjusted when installed/replaced ???

This member may have mis-typed, but Zack IS correct and Jimster480 is mistaken and has provided erroneous information. Consult the Factory Helm's Inc. Service Manual for the proper TPS replacement procedure if you question the information that I have stated/provided above.

In my original post I say to get a multi-meter.
The TPS doesn't normally need to be calibrated as I said originally.
There isn't too much play in the holes overall and if you place the new sensor in the same position then it will be fine in most scenarios (notice how I used the word "usually").
The OPs issue of the CEL being on (meaning no TPS sensor detected, as a 5v reading from the TPS DOESN'T THROW a CEL) and then replacing the CEL is not a "calibration" problem as I mentioned. Its a problem with his wiring/plug.

A common mistake is swapping the two 3P plugs for the MAP and the TPS. The one that has a solid white wire goes on the MAP.
