[@joseluisotanez3684]

Hermano Dios mío muchas gracias excelente test.

[@lisacontreras6100]

Absolutely fantastic work. Helped me confirm that my throttle body was defective. Cannot thank you enough. Test was performed on a 2013 Chevy Silverado WT 6cyl 4.3L. Test 4 was higher Ohms as in some other cases below. My throttle failed Test 1 & 2. Initially had passed Test 1. Also had Ohm breaks in Test 2 where it went to OL briefly. Didn't see your throttle do that when pressing down on butterfly. Tried to run test again to verify and then it failed Test 1 completely. Yes, I verified the leads were in the correct position and did another test to be triple sure. Went straight to OL both times. A million thanks. Let me know if you guys want me to post my video results to see what it looked like in the comments. Bravo!!

[@homeehsan7007]

Great information

[@davidtravale6237]

I used your diagnostic method to check a six wire 2009 Chevy Malibu 2.4 L throttle body assembly. You're recommendation to use alligator clips was spot on. Would have been very difficult without them. I couple of differences with the 4 cyl vehicle. Test 2 & 3 were opposite polarity (i.e. opposite polarity when butterfly was opened or closed) but they seemed to have smooth resistance changes with no jumps. Test 4 the resting resistance was higher, 30 Ohms, but not open (OL) or zero. So i think the concept works on the 2.4 L engine but the system wiring or logic is different for the 4cyl model. Haven't put the car back together but I expect my throttle body is OK now.

[@alexanderproefrock8721]

Hey I definitely could use your help!! I'm dealing with the 2.4 myself and TB codes.

[@davidtravale6237]

I used the method in this KZbin video to rule out the TB. I could be wrong tho. I have a few sensor codes all related to the ECM so I have a new one on order. If that not it it’s either a no spark or no fuel issue. I reconnected all connections using a product called Stabilant 22. It’s supposed to improve bad connections. That didn’t work either.

[@velox731]

@@josemenchaca3944 I had less than 1 ohm on the last test. Watch for defective GM parts... after receiving and installing the new tb I was still having the same problem.

Thank you for posting this. Is it possible that this will also apply to European GM cars - eg Opel Meriva A throttle body?

[@mckoylach1622]

Do these methods applied to foreign vehicles,too or every car is different,depending upon the manufacturer? Thanks,great tutorial video...

[@emrahkadric8327]

Would this rest work on a 2011 Equinox? I on the video says 2007-2009. Also just to confirm mine passed the first 3 tests but on the last one Red on A and Black on B I got no reading. Even though 3/4 passed would you recommend replacing the throttle body ?

[@sherekant1981]

Tienes mas diagnostocos para otros tipos de vehiculos? o donde puedo conseguir los valores de los diagnosticos?

[@mohammedrifaat5701]

Thank you very much for the information very useful video, I checked my motor ohm and the reading is 8K ohm, is that mean I need to replace the throttle? My car is Mitsubishi outlander 2009. Waiting for your reply please

[@nickkelly8795]

Hi, really helpful video, I have a Mazda 5 sport 2007, that will not rev over 2000rpm, the connectors on mine are all in a row six pins, would know the correct pin to use, to reproduce your test,, a big thanks if you can help

[@A0d0i00]

It is best to use analog multimeters for such measurements. Moving the throttle will show an immediate error in the resistor path. Measurements with an electronic multimeter are subject to errors resulting from the measurement itself. Digital devices simply do not perform linear measurement, but perform so-called sampling from time to time. And this means that a value that changes linearly is not really presented to us linearly. Therefore, it is worth returning to this type of measurements with old linear multimeters. Apart from that, the presentation is great. Thenks.

[@BongoisaPyro]

For those who are asking if this works on your electronic throttle body the answer is yes. It will have different readings but the procedure is the same.

[@CTSVTWINS]

Great video. Does this test method apply to the TB on a 2010 ZO6 Corvette with the LS7 which has the all aluminum TB and the actuator is also all aluminum? TB part number is 12570790. Thanks.

[@scooterdoo2036]

Will this procedure work on a 2007 Saturn Ion 2.2?

[@luisgarcia9293]

Le metiste los 12v de la baterial o usaste otra pila de otro voltaje?

[@inhocsigno9151]

My 2006 Sierra 4x4 has the TAC Motor on pins A & C, which measures 1.6 ohm. Surprised there is so much variation between different automobile lines.

[@aeromastersargentina6579]

I have a question. My car is a gm Astra 2007. It has a 2.4 liter 4 cylinder 16 valves and a throtle body magneti marelli very.similar that you show in the video. My fail is when the car stays at idle. The car runs perfect but when i press the gas pedal a tinny the car fails like he want to stall out. And when you start at cold in the morning feels like starts in 3 cylinders and at 4 seconds pass to 4 cylinders. I clean the throttle body and te car works better but that issue its make me crazy. The sparks plug are new. People told me change the spark leads. Thank you

[@ricardotiger2601]

Good video, but I'm driving a 2006 opel meriva and have no voltage to my throttle body actuator/motor. Any solutions?

Great tutorial! This throttle body looks very similar to the one on my 2018 GM 5.3L Silverado. Do you think the pinouts and trends you outlined in this video would be similar for my TB?

[@tecman129]

The test procedure is the same, but the terminals that are checked will be different. At the moment, I don't have the info the give you the updated instructions for your particular application.

@@bthayer7797 I didn't get the values, could not find them anywhere. I ended up replacing the throttle body, that fixed the issue. Beware the relearning procedure is a major bitch, be patient.

[@bbroncs]

@@bthayer7797 it was a youtube video, i watched several, i do not remember exactly which one, all i remeber is the video showed a very basic, manual relearning procedure without the fancy and expensive scanner, it took me several tries and several hours.

@@bbroncs gotcha thanks. One last question, what were your original symptoms?

[@kaaraa-mardha1977]

Thanks for tutorial, there are 6 pins, how do I know which terminals are E and C out of 6 pins please?

[@garysincliar]

Hi there, Is the E connect to the ground or signal wire to ECM or connect to the 5v?

[@stefanalex7164]

Hi terminal C is the shared ground and trrminal E the shared 5V ref ? Thamks

[@TheMusaiz333]

So when doing this test, connecting the red to D and black to E shows absolutely no reading at all, connecting red to A and black to B also shows no reading at all. The other positions do show readings though. Does that mean my throttle body (VQ35, looks very similar to the one in this video) is faulty?

[@dtnel]

Wish he'd said what was what as in ground, pos , neg on other pinouts as wanted to apply same principal to 2010 Dodge Grand Caravan and see if worked on one I have on bench.

[@rotaryskratch18]

I'll run these tests, but I first checked the 6 pin connector. Yellow and Brown wires go to the throttle motor from the ECM. TAC Motor Control 1 and 2. The other wires are low ref/signal wires, most reading 5v. I'm only getting 4.43mV and 10.7mV on the Yellow and Brown wires (disconnected, ignition on), but i feel like one should be roughly battery voltage and one should be ground. I'd just hate to replace the throttle body and still have a problem.

What if the TPS2 test is opened loop for the 2 test terminals?

[@AGhostRiderR]

Dose this work for ls3 throttle bodys?

[@rnonbelive7612]

H2 ,2005years. Vortex engine 6.0L . Throttle connect is same too

[@lonewolf744]

What if you get all passing number on the test. Could the throttle body still be hanging up and not opening or closing all the way properly because of being dirty ect?? My throttle is sticking. The rpm will stay up after tapping the gas but taking my foot off the gas. I'm having rough idle loss of power and I think my chevy express even went into limp mode twice but then came out of it. It will run kinda ok sometimes but really bad other times. I've already replaced a lot of other parts trying to chase the issue down. I was getting o2 sensor codes replaced all them. Replaced maf sensor. All the plugs , coils and wires. Vapor vent canister solenoid .

[@genetti10394]

Did you ever find out the solution?

[@gstacks510]

Hi, I need some help, I opened the butterfly valve to clean it while the throttle was still connected to vehicle... my car would only start for a couple of seconds then die. I replaced the throttle thinking that was the problem and still does the same thing. Im getting code p2101 along with other codes that were already there before I even touched the car. I checked for any corrosion or loose wires/bad connectors/harnesses and everything looks fine. I tried a reset (connecting the negative and positive battery terminal together) and to no avail. Also I should mention that I can press on the gas a good amount and the throttle will respond. But not when I depress it only slightly or moderately(when car is on). Can anyone help?
