Insert the key into the ignition and start the engine. - Tighten tps sensor down & adjust idle setting screw shown in the pic below. The TPS is now set and the horizontal throttle body stop screw (7) should not be touched again. The manual has you place a 0.0177" (0.45mm) feeler guage between the stop screw and the throttle pulley to open the butterfly and then adjust the TPS right to where the IPS (pins 3 and 4) switches from closed … First set airbypass screws to 0 by screwing all the way in. The red or positive (+) wire on your multimeter will go to the pin in the green wire. If the throttle position sensor test does not reach 5 volts, this is a sign that the throttle position sensor needs to be replaced. Throttle position sensor. If you want to do it "right" and not pierce the wire insullation, you can buy the Polaris TPS adjustment harness (Polaris part # … The FSM procedure is to set where the IPS opens and closed in relation to throttle shaft opening. (Yes, and I know this doesn't add up to 5080 in both cases. This vital sensor allows your engine to maintain a proper amount of air. How to Adjust the Throttle Position Sensor Before adjusting the TPS make sure that you do a carb sync and set the idle speed beforehand as this could effect the reading. This can be viewed most easily with an analog multimeter, but a digital multimeter works as well. The multimeter range has to be set to the correct maximum voltage for the circuit in order to get the most accurate result possible. Minimum differences in TPS position make big changes on TPS tool readings. Reconnect temp sensor. Then unscrew Idle screw so Throttle injector butterflys are fully seated == no tickover. If the digital multimeter reads between .2 to 1.5 volts, then the throttle position sensor is working correctly. ... All you need from the tools is a multimeter. The owner of the video made it private.

The voltage should fluctuate between 0.1 and 5v depending on the engine load. I couldn't get the idle under 1400 until I took the TPS off and turned the "double smile" so that it would catch the butterfly lever while it was completely closed. A modern car consists of many components and assemblies. 2G's critical adjustment is the Idle Position Switch that's part of the TPS. To test this sharply open the throttle and watch for the voltage change, under high vacuum (e.g. From what I can tell 2G's TPS adjustment procedure is different than what I've posted for 1G's. Not very big. The factory spec for TPS voltage on a 2G is so wide that it's only to verify defective TPS's. .65mm (.026 inch) Feeler Gauge 4. Still, I now have some reference figures.) Wire Colour & Purpose P= +5V reference Y= TPS position signal to ECU BR= TPS idle switch BK/DB= sensor ground. I loosened the TPS and moved it until the voltage was 0.99-1.00V on my multimeter and then tightened the screws back down. Maybe enlarging slightly sidewards the original Duke 390 TPS fixing holes with a Dremel or a drill (carefully) should provide more than enough room to do the adjustment. RESISTANCE TEST: is only to test the tps. And even a malfunction of the smallest of them can lead to very serious consequences. Set this reading to exactly .700 , this is done by loosening the 2 screws on the TPS sensor which is on the MAG side throttle body. Adjust this until the idle reading on the tps is about 0.48-0.49v. Slapped the multimeter on the terminals and received a reading of 794Ω as below. As you open the throttle plate, the digital multimeter should increase to 5 volts. (3.5 Nm) when the voltage is 0.70 +/- 0.01 Vdc. Dave Ex HVUK, Aug 10, 2011 #6 It is nothing more than a variable resistor and can be checked with Digital Multimeter (DMM). The only apparent difference is holes in the TPS the fixing mount to allow adjustment. TPS Adjust (mechanical) Engine off. Wait a minute for the engine idle to level off, then use a pen and paper to write down the RPMs that your engine settles and idles at. To test the TPS you don't need a scan tool (although having one is major plus). Car does not have to be running, but ignition needs to be on to get 5v feed going to tps connector. if you quickly open the throttle fully) the voltage value should quickly change to 4.5+v and then settle … You basically screw the sensor enough so that you can still move it around. I have Kpro but was told I needed to calibrate the TPS with the multimeter before setting it up in KManager. 1) Locate the TPS on your vehicle. Open and close the throttle a few times to check the idle setting is stable and adjust if required. If you have a logger that will show the actual value of the idle position switch then you can use it to replace the multimeter for measuring continuity. TPS Adjustment procedure Short Version.....adjusting the idle voltage (1) Find the yellow wire leading to the TPS and carefully pierce the insullation with the positive lead of your multimeter (make sure that you seal that bare spot when finished). To check and adjust the TPS you'll need a digital multimeter, two small straight pins, and a screw driver. Rotate tps slightly until you can get your settings. Start the engine and take note of the idle RPMs. Disconnect 3 wire harness. Circuit (Wire) Descriptions of the TPS. Adjust it until its at .65 volts on the multimeter. If the multimeter displays a negative number, for example, the probes are most likely in the wrong place. To make your voltage adjustment, loosen 2 small screws that hold clamps that hold the tps. Volume controls, tone controls, and balance controls are all three-terminal potentiometers. Using the TPS test tool, verify the TPS is set to 0.70 +/- 0.01 Vdc. This causes your throttle position sensor to adjust the engine intake manifold accordingly. Some may also elect on making jumper wires to go from the TPS connector to the TPS and attach the voltmeter, via clip-leads. If you are lucky enough to have a scanner (Auto XRay Scanner) and know how to incorporate this into this adjustment, by all means … go right ahead! When installing and adjusting the TPS, some tips: 1. Tighten 2 screws. Here's a brief tutorial on my method of adjusting the APS (accelerator position sensor) on a Kia Forte. This is not described in any of the FSM's or schematics I have. How the Throttle Position Sensor (TPS) Works. 6. You either have to get k-pro, or spend $20 and buy a multimeter. I went out to the shed after reading your post on the TPS adjustment. This is a pretty simple test that can be easily be done with a multimeter. I fired it up basically cold and the idle was much better and smoother than before but seemed like it was just a tad too fast. The throttle position sensor (TPS) can be tested using a simple multimeter and in this tutorial I'll show you how in a step-by-step way. Here are the contents of this tutorial at a glance: Symptoms of a Bad Throttle Position Sensor (TPS). Step 1: Gather your tools A. Multimeter (set to DC voltage- 20 scale) B. TEST 1: Testing the Throttle Position Sensor Voltage Signal. Screw it all the way, but try to be as still as possible as any sudden movement will change the value on the multimeter. You may need to let the engine run for a few minutes in order for it to come down to its normal idle speed. Open the throttle rotor to WOT and keep rotating the sensor until you get the output shown on the multimeter to 4.5v. Then use the idle adjustment screw to adjust idle voltage. Set your meter to 10kΩ. To hook the multimeter up you will have to pierce the green wire (red arrows) with a pin so you can check how much voltage is going through it. The TPS set up routine reads the mv value of the TPS with the throttle closed and stores this value in the ECU as the baseline for the fuelling. Connect ohmeter to 2 bottom pins (BR and BK/DB) and you should get continuity. In this tutorial, we're gonna' test the throttle position sensor part of the TPS assembly. ... You can adjust the position of the TPS with a multimeter but you need to know what value is stored in the ECU to set it up correctly. Screw Driver (Philips) 3. TPS is a fancy new name for the old three-terminal potentiometer that is commonly known by many different names. 7mm socket with extension and a lot of patience. *note: This post covers the accelerator position sensor (APS) not the throttle position sensor (TPS). TPS Adjustment Procedure and Testing Procedure - Coming soon IAC Test Procedure This is the Throttle Position Sensor Adjustment Procedure. Either my multimeter is off, or there's some additional resistance in there. To adjust the TPS all you have to do is loosen (don't take them out) both screws and move the TPS until you see the right voltage. This feature is dependent on the throttle valve. Should be about 0.49v @ idle, and 4.5v @ WOT. WOT setting is more important than idle. The FSM requires an OBDII to check current data of the throttle position while adjusting … This will take a while to do since the sensor is very hard to adjust due to its sensitivity. Picture 2 To hook the multimeter up you will have to pierce the green wire with a pin so you can check how much voltage is going through it. What Is a Throttle Position Sensor? Detach TPS connector. This is a very touchy adjustment and your reading will likely change slightly when you tighten the screws back up, you need to compensate for this change when adjusting, it needs to be .700 when tight. My car read .675 and obviously when I moved the throttle reel, the throttle motor will move the TPS and the voltage will raise. I'm wondering whether it is normal to not be able to get a .45V reading as at idle the TB is being held open via the set screw, and I'm getting the correct 4.5V at WOT. go back to the engine bay and loosen the two philip screws that hold the TPS on the throttle body then and tighten until snugish, turn the TPS left to right while waching the multimeter you want it to be .50v. You need a good digital multimeter to set TPS ( Throttle position Sensor) and a good set of Vacuum balancer guages or carbtune sticks. To adjust the TPS base-line, slightly loosen the screws, then slowly turn the TPS clockwise or counter-clockwise to adjust the voltage.
