The most popular variant of the series is the F-150. So we've got two voltage points and we've got two manifold absolute pressure values that coincide with those points. In this case we're going to start at minus 20 degrees and we're going to move in 10 degree steps. So this is a zero to five volt sensor and it outputs a voltage that's relative to the pressure that the sensor is measuring. Open the Tools menu and select Calibrate TPS: And these will be distinguished from the acutal main power grounds. Once we've gone through and calibrated a sensor, we always want to look at the data that the ECU is then reporting from the sensor and just go through a sanity check. How to Calibrate your TPS 1. Finally once we've gone through the procedure of calibrating the sensor, we can then confirm the reading that we are getting in the ECU. This is the data that we're going to use to calibrate the sensor into the ECU. So we're going to select analog voltage one, which currently isn't being used. And then at output value B, we're 150 psi, so that's got our sensor calibrated there, and we're good to go. One of the most important pre-start configuration tasks with any ECU is to ensure that the sensors wired to the ECU are configured correctly and reading accurately. And we end up from our variable resistance with a voltage output at that pin to the ECU. What we've done is we've taken our reference voltage, in this case I've put the reference voltage in our pull up resistor values up here on the right hand side. Now we've looked now at our analog voltage inputs, so we'll move on and we'll talk about our thermistor inputs, our negative temperature coefficient thermistor inputs. So we should at least know if we're within a few degrees of that temperature. OK let's move into questions, we'll see if we do have any questions there. This is why the feeler gauges are used. Edited by paparazzi, 20 December 2011 - 10:10 AM. Sign in here, Endorsed by leading performance manufactures. The TPS should read between 4.0 and 5.5 volts. Normally these will be at 0.5 volts and 4.5 volts. And I'm gonna show you how that can be done. Now let's just jump across though before we do that to our Link G4 Plus software again. 4. So this is used for measuring, in this case we're actually using it for measuring exhaust manifold back pressure, obviously could be used for measuring a range of different properties where we're interested in a range that will span between zero and 150 psi. So we want to give a little bit of though to this as well. If we jump back to our diagram here for a moment, remember this is what's going on. We're going to touch on that briefly because the wiring is really the first part here, the first step, in making sure that we've got reliable data from our sensors. Difference here, this is respective to the Link G4 Plus brand, the Cal tables allow us to calibrate a non linear sensor. Now the problem is if we share that signal off to our aftermarket ECU, if we don't have the ability to disable the pull up resistor inside the aftermarket ECU, we're now sharing the signal, we've got two pull up resistors, it's going to basically mean that we can't get viable data from that sensor. So what this does, let's just have a quick look at a pull up resistor, if we can jump across to my laptop screen again. Again we're looking for very accurate voltage signals, and we want to make sure that the accuracy of those signals is maintained and that's why you're going to find that your ECU has a number for dedicated ground pins on the header plug and these will usually be labelled as something like sensor zero volt or sensor ground. Now we'll start by discussing the importance of calibrating the sensors into the ECU. This indicator is a vague symptom, as it could also point to a variety of issues, but you can expect to see it if there’s any issue with your throttle position sensor. We can see that's currently reporting 19.3 degrees. This is a 150 psi pressure sensor. Then what we can do is open our cal table, and we can see now we've got our x axis set up in degrees centigrade, based on the break points that we've already programmed in, and then all we do is take our manufacturer's data here in terms of the resistance and we can enter that directly into the calibration table and everything's going to work from there. With TPMS Button. Slowly depress the accelerator pedal all the way to the floor. At the same time, while it's not directly related to our sensor wiring, just to make sure that our ECU is correctly wired, that's also important. So with this we can generate a y value, in this case y is our MAP value. He mentioned that M1.3 cars have 3 wires, and that at WOT there should be continuity between the brown/black and ground. After reading the forums I thought it would be an easy job and didnt bother taking notes of the factory settings lol. Now as usual we will be having questions and answers at the end of today's webinar so if there's anything that I discuss that you'd like me to go into more detail on, or anything relating to sensors and sensor calibration with our ECUs that you'd like me to discuss, please put that into the comments or the chat and the guys will transfer those through to me, we'll deal with those at the end. Of course for our members if you do have any questions that crop up after this webinar has aired, please feel free to ask those in the webinar section of the forum and I'll be happy to answer them there. So what we've got here is our fixed pull up resistor. Before replacing the sensor, try the calibration procedure: 1. Alright we'll just head back to my notes for a second. So this is really incredibly easy if we understand some real basic electronics here and we understand ohms law. Note: Occaisonally a TPS will need the moon shaped grooves honed out a bit with a rat tail file to get enough adjustment, but normally the trick of moving the sensor as far foward as possible gives enough adjustment. It's really important to make sure that you don't use the incorrect voltage supply there for your sensor. OK so let's just have a quick look at a couple of examples here. 3) Insert the appropriate feeler gauge into the throttle assembly. Before Speeduino can work correctly with your engine, you will also need to Calibrate the Throttle Position Sensor. If we were looking at another sensor, maybe for our engine coolant temperature, it would be sensible if the sensor went faulty, to default to an engine coolant temperature that was high enough to run our engine cooling fan, so we might want to default to maybe 100 degrees centigrade or something like that. Altern… Does the number we're seeing make sense? And this is the variable resistance that comes from our NTC sensor. These normally need to be terminated to a clean point on our engine block.
