Thanks for the valuable feedback. ECT sensors are NTC sensors, thermistors containing materials that have less resistance as temperature increases. Automotive heating and air conditioning control modules also use ambient and in-cabin NTC sensors to monitor outside and inside air temperature. See www.freeasestudyguides.com/ac-negative-temperature-coefficient-sensors.html - Good Luck Matt!

Thanks for stopping by OldSchoolNoe . That's true. Moisture is horrendous; remember that it freezes in the expansion valve. This problem can result in warm air midway through the test drive. - see www.freeasestudyguides.com/ac-frozen-expansion-valve.html - n - Good Luck with the A7!

Good Luck elefanny1106!

Brooo😂

That's great, here's a few quizzes that may help! www.freeasestudyguides.com/a8-engine-performance-quiz-1.html - Good luck OldSchoolNoe!

Good luck on the A4 OldSchoolNoe!

That's great! Good luck with everything, Mario!

Thanks for the feedback - For more on step bore quick take up master cylinders see www.freeasestudyguides.com/brakes-quick-take-up-master-cylinder.html - Good Luck with the A5 OldSchoolNoe!

That's great! Congrats and Good luck with the A8 ttrbykir!

Did you pass

@Johnny G yes sir, got 47/50 lol! Did lots of studying, and these videos helped too!

Good luck Soiled Grandpa!

Thanks for the feedback, the video is right, Answer D is correct, neither technician is correct. A stuck open wastegate results in under boost and a stuck closed results in over boost.

I rewatched it and understand now. I thought it was saying both techs were right. Thanks for the reply!

Read the questions carefully bro, can’t afford to make mistakes like that during an exam. Good luck!

@@justaman3817 This was a while ago. I passed a1-a6 so far. Studying for 7-9 now. Thank you!

That's great. Congratulations! You took time and studied for each exam, and that was key. Good luck, thanks for visiting www.freeasestudyguides.com -n- thanks for the thumbs up Morning Mist!

Good Luck Frank!

Fr bruh

Different manufacturers have different terminology, study more bro, knowledge is power 👍🏽

I thought the same thing, until I realized in the next slide, "insulation" was a typo and they meant to write "secondary ignition".

@@ace1usmc ahhhhh good catch!

Good Luck on the ASEs!

Thanks for the comment, Lou! Welcome back. The tests are timed now, available all year, and proctored at Prometric. Visit the A5 Study Guide on the website www.freeasestudyguides.com. It has 60 A5 Q&A. If you are unsure of an answer, use the Read more... section. The tests can be tricky, so we suggest taking time and studying for the exam. Use the study tips www.freeasestudyguides.com/studytips.html - Good luck, Lou!

Thanks for the comment, Jesse; Much Appreciated! The A1 Study Guide on the website www.freeasestudyguides.com also has 75 A1 Q&A. Good luck with the A1!

Thanks for the comment, Blasian; www.freeasestudyguides.com/ has more A6 questions with detailed explanations. Good Luck with the ASEs!

dont feel bad man. it sucks but you can take it again (also there are a ton of free quizes that are almost word-for-word)

Good Luck Justin!

Thanks for the comment, Mark! The unit requires a solid vacuum to operate correctly. Answer B is correct because 10 hg" of vacuum is low and can cause problems engaging and holding 4X4. If only 10 hg" of vacuum is found, check for vacuum leaks between the manifold, case, and the actuator. The actuator also contains a diaphragm that can leak. Good luck with the A3 exam!

i hope you studied more and learned to read the questions carefully.

Thanks for the positive feedback, Daniel, and Good Luck with the ASEs!

Thanks! I passed A3 yesterday. All I have left is automatic transmissions and I'll be master tech. Your videos help a lot, keep it up man!

Thanks for the comment Young Malcolm! Vehicle riding height or ground clearance is a vital measurement that's checked before performing a wheel alignment. It affects the toe, caster, and camber angles. Measurements are taken with a tape measure or special tool from the ground to the fender well, bumper, control arm, etc. Check for the manufacturer's specifications before taking the vehicle's height measurement. Typically sagging coils, leaf springs, suspension airbags, or torsion bars are at fault. Check the control arm bushings for wear or damage before condemning any spring. Vehicle manufacturers have different specifications and techniques for measuring ride height. Usually, if the vehicle sags more than an inch from front to rear or side to side, it is out of specifications. Always check the sticker in the door frame for the correct tire size. A larger or smaller diameter tire also affects the curb ride height measurements. Good luck with the ASE's!

Thanks for the comment Cano Bear! Comment: "question one is incorrect, the camber is out of spec. that also isn't how alignment specs have looked for fifty years." Answer: The caster in this vehicle is four degrees plus or minus one-half degrees (.5°). The vehicle's actual caster angles are within specifications. The camber angle is read one degree plus or minus 30 minutes. The (') or minutes symbol is used to view or represent angles, just like an actual clock. The thirty minutes reading equals one-half degree. Notice the 45' or forty-five minute reading for the RF. It is equal to .75° (decimal degrees). The camber is 15' or .25 degrees off; 15' or .25 degrees is within specifications ('30 minutes/.5 degrees). The specifications for the toe are in fractions of an inch. It is negative one-quarter of an inch plus or minus one-eighth of an inch. If there is no negative sign preceding the number, it is assumed positive. Technician A is correct; the vehicle in the chart is within specifications. Comment: "in question 4, you answer D; the horn switch causes the steering wheel to squeak, then your explanation is seemingly for Comment: answer C...never heard of a horn switch causing a noise on a steering wheel, guys." Answer: That is because question 4 is an Except-type question: the steering coupling, the clockspring, the steering column bearings, and the horn switch. The horn switch is fixed and not likely to make noise. Answer D is correct. Comment: "question 6 is incorrect, caster does not affect "shimmy" and was in spec according to your own chart. Answer: Question 6 the vehicle in the chart has excessive caster, Caster is viewed from the side of the vehicle. It is the forward or rearward tilt of the steering axis. A positive caster provides steering wheel returnability and greater stability. Excessive positive caster causes hard steering, wheel snap-back, and shimmy. A negative caster is rare and typically used on heavy-duty applications. It can result in instability and wander. Answer D is correct. Comment: ...question 8 is incorrect...an f250 with hd suspension has a solid fron axle with a parallelogram steering system with a PITMAN ARM and strut rods go on cars WITH STRUTS and not a solid front axle" Answer: Pitman arms are attached to the steering gearbox and linkage of parallelogram steering systems. Coil springs are used in suspension systems. Solid drive axles are held in place and prevented from excess movement with control arms, strut rods, and track bars. Due to their design and small contact area on the chassis, coil spring suspension systems usually require more control arms and links than other types. Good luck with the ASE's!

Thanks for the comment on intermediate shafts, Young Malcolm! It reminds us that intermediate shafts have universal joints that can bind or cause looseness while turning the steering wheel when worn. Technician A mentions a binding universal joint that binds then releases. Technician B mentions that the intermediate shaft may have a binding universal joint-they are both correct. Loose universal joints are more common and typically easy to diagnose. The steering wheel will have an excessive play with the vehicle at rest. Ex. Turning the steering wheel an inch or so in each direction will have little or no effect on turning the front wheels. Have an assistant turn the steering while visually inspecting the shaft, universal joints, and linkage for looseness and play. Good Luck!

That's a great question! B is also correct because the transmission cooler is in the coolest well of the engine's radiator. The engine's coolant flowing past the cooler removes heat from the transmission fluid. That's why an overheating engine will also affect the temperature of the transmission fluid. The excessive heat causes the fluid to expand and push through the transmission vent located on the top of the transmission case. Good Luck Supra7602jz!
