I highly advise not spraying directly into the throttle body because of the electrical module. The spray is so atomized it has the tendency to work it’s way into the housing for the potentiometer. What we do at the shop is spray it onto a microfiber rag and wipe around where the throttle plate rests at idle. If your hand is too big use a pipe cleaner wrapped in the microfiber. The service your referring to also included the induction system. The Jukes are Direct Injected with Gasoline (that’s what the DIG stands for on your engine cover). With all direct injected cars the valves don’t get cleaned by the gasoline spraying over them. The injectors are mounted to spray directly into the combustion chamber. In addition because the Juke is turbocharged and it’s equipped with Eco-Drive (Eco-Drive basically means it recirculates the Exhuast waste) the valves get hit with oil and “dirty” air each combustion cycle. Some earlier model year Jukes have a sprung hose clamp with an 8mm head if I recall correctly. These clamps have a very specific torque that I can’t remember. The torque is relatively low and is there because if under torqued it can allow unmetered air in and if over torqued the throttle body housing won’t have room to expand.
Once you cleaned it and put everything back together, were there any codes or check engine lights that came on? Did the computer have to re-learn anything? Usually they recommend not touching or moving the butterfly with your hands on any of these newer throttle body units.
Thank you for this video! In my experience, finding I have a problem is much more overwhelming than actually fixing it. For 30 years now, I've done nearly all of my own repairs. I started out with a Fiero. Learned a lot on that one! The only thing I didn't do myself was replace the transmission. But if I'd had the necessary equipment, I might have.
Hopefully the dealer was trying to sell you a Induction service for $305 and not a just TB serve. cause that would be a huge rip off. Nice video and this will definitely save people some money to do it themselves.
P2018 code being thrown on my 2015 awd sv. I'd like to know if that is upper throttle position sensor, that is what code points to. If you find out, give me a heads up if you can! Thx.
do i need to take out the negative car battery cable? i install a new air flow sensor to my 2011 Nissan Juke but it still has the engine light. i got it for $130 in AutoZone.
