What is ECU TPS?
A Throttle Position Sensor (TPS) is required by the Elite ECU for many purposes. It can be used for the load input for some application. It is also used with Idle Control, Decel Cut, Transient Throttle, and many other functions. A TPS is a powered sensor that typically has three wires.
Is there a way to adjust the TPS?
In order to adjust the TPS the manual says to measure voltage at the TPS by inserting meter probes into the plug at the ECU plug connection.
Can a TPS be adjusted to half a volt?
You should have no trouble in setting things at exactly half a volt. Before removing the TPS or altering the original setting it is a good idea to mark the mating castings with a scratch so that one can check on the adjustment, before and after, as a matter of interest. It is always nice to know if the effort expended has in fact improved things.
How do you adjust the voltage on a gas engine?
Connect all connectors. 2. loosen TPS fixing screws. 3. Turn ignition on. 4. Adjust TPS position, (i.e. rotate the complete assembly), while throttle valve is confirmed FULLY closed, to specified voltage, using a volt meter. 5. tighten fixing screws. The voltage is specified as within a tolerance of from 0.45 to 0.55 volts.
How to adjust the throttle position on a car?
Now from the book :– 1. Connect all connectors. 2. loosen TPS fixing screws. 3. Turn ignition on. 4. Adjust TPS position, (i.e. rotate the complete assembly), while throttle valve is confirmed FULLY closed, to specified voltage, using a volt meter. 5. tighten fixing screws. The voltage is specified as within a tolerance of from 0.45 to 0.55 volts.
How to adjust TPS voltage step by step?
This is done by turning the adjusting screw (2.5mm allen) back in, slowly turn that in until your voltage reading is .940 then tighten the 8mm jam nut while holding the 2.5mm screw. Your reading is going to increase and once again you need to compensate for this and make sure your at .940 when the jam nut is tight. Thats it, your DONE!
How does the ECU interpret the TPS feedback loop?
The ECU uses the voltage in the TPS feedback loop to interpret throttle position, simple as that. 1.2v and under, the ECU assumes idle. As the voltage in the feedback loop approaches 5v, the ECU then sees WOT. Simple as that. NOT… Bad logic, plain and simple.
Can a TPS be adjusted while the car is running?
It then uses that as it’s “throttle closed” benchmark. If you adjust the TPS while the car is running, you can make the idle go up and down. If you leave the TPS adjusted so the idle is high, turn off the car and turn the car back on, the idle will return to normal.
How do you adjust TPS on a snowest?
Now you need to unhook the throttle cable from the flipper, just go WOT and hold the cable with your other hand and you can push the cable out of the flipper. Next you need to go back to the adjusting screw, loosen the jam nut and then back it off 2-3 turns and make sure the screw is no longer touching the cam on the throttle shaft.
