Well, I'm trying to diagnose some issues with the swap we just completed. (B16A2 into a 97 Civic HX coupe)

It's redlining at around 2700rpm so the Throttle Position Sensor might have to be calibrated since a new ECU is being used. I was told that there are some adjustment screws/bolts you can change?

 

Uhmmmm ... No .....


I believe you need to correct/calibrate your Voltage on your TPS Sensor friend, not bolts or screws to correct problem. Usually people use a digital-volt ohmmeter to read the signal & compare to against manual.

DUH: I forgot the answer to your second question. To correct it I've seen people use their VAFC or SAFC on the fly !!!

Remember this Throttle Position Sensor is the only way the computer knows where your foot is...

The TPS is screwed into the Throttle body and sits directly above/side the throttle plate. The plate has a tab that extends upward into the TPS. The TPS has a small plastic rotating insertion that directly connects it to the plates (tab) movement.

A simple way to realize what the TPS is, is to think of it as a volume ****, as you turn the **** the volume changes, where the throttle plate turns the TPS the voltage changes.


Here's the "Ghetto Way" to fix it if you think the voltage is off a "bit".

1) Dremel-off or Cut off rivetts from TPS unit, then remove sensor & bolt like screws. (You will need to replace with New Bolts when replacing)
2) Check to make sure you have TB @ closed position "full flush plate".
3) Re-install back with Key On, Engine OFF !!!
4) Rotate or twist the TPS till desired voltage.
5) Hold TPS in exact position and tighten in with NEW Bolts to keep it from rotating.

all you need to do is make tabs on the tps and loosen them and move it left to right to get the right idle. which ecu are you using??

 

Here some pics (just in case):

He is using a 97 gsr ecu...Its my car that doesnt work ..lol..any help on what we need to do would be great, and what the voltage should be is even better...thanx guys

 

tps wont cause a low rev limit.
usually thats caused by a bad sensor in the dist. is the check engine light on?

 

Good info guys. But remember TPS sensor is kinda like the distributor in which it can be advanced or retarded also. I currently probably need to adjust mine since I am getting crappy gas mileage.. I need to know what are the voltage numbers I should be looking for though. I will probably try to get this done sometime this week.

Idle: ?
WOT: ?
