Feb 05, 2017 · The scan tools data list indicates that the TPS signal wire voltage is at 5.0 volts at closed throttle, and then ranges up to 11.5 volts. A back probe of the TPS signal wire (usually is an Orange/Dk Blue wire), shows 5.7 volts at closed throttle, with a similar rise in voltage as the throttle is opened. A check of the TPS 5 volt supply and ground circuit prove that both of these circuits are good. A check of the TPS signal wire with the TPS disconnected shows the same 5.7 volts.
The second wire is the TPS sensor's 5 volt power supply which comes from the Spectre eMS-pro: this lead is labeled "TPS VREF" in the Spectre eMS-pro Typically the center wire in the connector plug is the TPS signal wire (or wiper of the Potentiometer that is used for this application), with the outer two...
Oct 01, 2014 · FIPL should be 1.1 volts in the closed position and no more than 4.5 volts at WOT. This is meaured by sticking a probe on the middle wire and the other to ground, then manually move the throttle from idle to full slowly looking not only for min/max but also bad spots in the range. I have mine set @ 1.09 volts.
• Reference Voltage for the sensor should range between 4.9 to 5.1 volts. • Check for proper ground at the three wire sensor, it should be under .050 volts. • Short the VREF to the signal wire, it should register the reference voltage at the scan tool. This checks the Voltage supply circuit and the PCM ability to read the signal.
If the idle is low and the TPS is high lots of problems will appear. If you need to grossly modify the TPS mounting holes to adjust Closed Throttle between 0.6-1.0 volts, you should recheck the idle stop screw first. Throttle Position Sensor Rotational Angle Signal Voltage 0 Under Travel 0.000 10 0.450 13 Closed Throttle 0.901 20 – 1.440 30 1 ...
12 volts, then just wire in a little LM7805 chip. Depending on your kit, you have either 3 or 4 wire signal. This applies to both the gps and the Connecting 4 wire gps to 4 wire radio is nearly as simple. Connecting 3 to 4 or 4 to 3 is often done with an interface piece.
The TPS sensor is a device that is simply a potentiometer, which is located to the axis of the throttle butterfly. It consists of a linear variable resistance, which is fed by a voltage of 5 volts that varies the proportional resistance with respect to the effect caused by this signal. It usually has 3 wires that are: One reference 5 volts, another ground and the third is a return signal.
If the signal is connected via a rectifier diode, the thermostat will maintain a floor/room temperature of 5°C. Pollution class: 2 Pollution class 2, representative of air circulation in typical homes. Overvoltage category: III Pulse voltage 4 kV to IEC 60664-1.
