Thanks for a very clear and concise explanation of testing. Most are just part swapping videos. As mentioned below, maybe put the car make in the title.
Testing this way works only if sensors are good. Most sensors will intermittently malfunction due to temp changes or solder cracks, giving wrong results. Easier to just change out the APP, save time. For those that don't understand kilo ohms, it means thousand. Nice video to explain how it works.
@@Ceasar91706 All electronics can malfunction intermittently especially if they are soldered with lead free and used in an environment with a wide temperature gradient.
Hey, I have a 2004 120i (e87) I have a sensor on the pedal I believe, does it have another one near the throttle body Or somewhere? Can't find much info about this. Thanks man, great video!
What if changing the sensor doesn't fix the problem? Also, what if every time it goes wrong, it goes into limp mode and throws a vsa light plus check engine? What would be the next thing to check?
If replacing the APPS doesn't fix the problem, then you would need to check other components in the electronic throttle control system, but the first thing to do (if you haven't done so already) would be to scan for trouble codes. The system really only consists of three main components (APPS, throttle body, and PCM), but there is quite a bit of wiring involved, and the trouble codes can give you a good idea of what to check next. If you're unable to retrieve the codes, then I would suggest removing the throttle body and cleaning it out with either electronics cleaner spray or 99% isopropyl alcohol (red HEET gas line antifreeze can be used as a substitute).
How can I tap into accelerator sensor signal without changing the signal parameters. I mean I want to connect a motor to linearly control it with pedal. But if I connect the sensor output to a mosfet (to run a motor), it might alter the signal and mess up the engine, or not ?
The holes are slotted and the sensor, if you have to replace it, how do you adjust it? I’ve searched all over the Internet and find no one addressing the slotted holes in the adjustment of this sensor.
I have been looking for decades, never found a butterfly in their. I have found a brass throttle valve inside carbs, TBI, SFI, MultiPort, drive-by-cable and drive-by-wire systems. I did find a June bug in the oil bath air cleaner of a 58 Ford truck once, but after all, it was used on the farm. Not even one moth, they are quick! ASE Master Tech since 1978 - Retired
Would this trigger a check engine light if it's bad? I got a hesitation that comes on once in a while I'm not sure if it's this or a bad throttle body..
@@9hoshiz no cause the hesitation is once in a while it's not a everyday thing I'm going to try some seaform one day and see if that fixes the problem..my mind keep telling me it's the fuel pump cause my hesitation only happens on hot sunny days esp when it's humid..
I subscribed within first min..super profesdional explanations of how system works..not just heres this thing im gonna swap it and hope that makes light go out
@CarsNToys, how are you doing sir ? I have a question what was really the issue that you were having with the pedal accelerator sensor? I ask you because Iam having a jerky transmission from first to second gear shift and I don’t have no check engine light one but I was reading a forum where some people say to have a same issue with they tranny and changing the pedal accelerator sensor fixed the issue.. that’s why I ask you what was the issue with it on your car ?
I took the plastic top off the sensor n there was about 1/4 slack in the cable. I loosened the nut on the right, then tightened the nut to the left, then tightened the right nut. It took a lot of play out of the gas pedal. Then I cleaned the mass sensor with mass sensor cleaner n removed the hose from throttle body n it was gummed up with carbon. I sprayed n cleaned it . I then put a bottle of cleaner in gas n after about 100 miles it’s s different car
Hello my dear professional colleague, could you give me the order of the connector pins, for example "pin 1 vcc, pin 2 signal, pin 3 gnd" I would be very grateful, I'm having problems with a Honda and because of that I'm going to try adapt this Acura TPS
I've replaced this sensor with 4 different ones.. and I can drive the car for a little over 2 hours the tcs light comes on and the triangle.. and when I stop the car will stall out.. have you use my thinkdiag scanner to clear everything to get it back going.. why?? I've been fighting with this for months.. I've replaced all sensors with oem and found faulty wiring and repaired them.. so lost.. car is now unreliable.. smh
I've a Nissan Sentra 2006 and I thought this video was NOT of throttle position sensor but of accelerator position sensor two very different sensors . My accelerator pedal sensor is located under / attached to pedal itself ..
From 2007-2008 Acura TL Factory Service Manual: "Check the accelerator pedal position sensor in the A/T DATA LIST with the HDS/Scan tool. Do not press the accelerator. Is the accelerator pedal position sensor opening 11 % and above? YES -Go to the APP sensor signal inspection. NO -Substitute a known-good PCM (see SUBSTITUTING THE PCM ) and recheck." - {Backprobe APP sensor wires with sensor plugged in} "[Wire color may vary] (LT BLU APS-A (ACCELERATOR PEDAL POSITION (APP) SENSOR A) Detects APP sensor A signal. With ignition switch ON (II) and accelerator pedal fully pressed: About 4.5 V. With ignition switch ON (II) and accelerator pedal released: About 1.0 V" " BLK APS-B (ACCELERATOR PEDAL POSITION (APP) SENSOR B) Detects APP sensor B signal.

من از ایران ویدیو اموزنده شما رو میبینم و فکر کنم که عجله کردم و پول قابل توجهی رو دور ریختم وبا اونکه خطای کمبود ولتاژ و چک کردن سیم کشی این قسمت رو دیده بودم اقدام به خرید سنسور موقعیت کردم و با اونکه تعجب کردم که مکانیزم ساده ای داره چرا خراب شده واینکه چرا فروشنده اینقدر گرون باهام حساب کرد،خلاصه که فکر کنم با اون هم مشگلم حل نمیشه وباید تستی رو که شما یاد دادید رو انجام بدم،خیلی ممنونم با اونکه انگلیسی دست وپا شکسته بلدم ولی از ویدیو ملتفت شدم که چکار کنم مرسی وممنون.....
