nissan sentra throttle body replacement

[@colinjoseph7276]

Cleaned my MAF & throttle body just now. Removed the negative battery terminal first. Assembled everything & started the engine. Engine sounds smoother now & idles slightly below 1000 rpm.

[@Unknown90010]

So you didnt have to do the relearn thing he was talking?

[@colinjoseph7276]

@@Unknown90010 you need to remove the negative terminal before you start working on the MAF sensor & throttle body so that the Settings in the ECU is not changed. Once the cleaning is completed just connect back the negative terminal & start the engine. This way, the ECU does not need to relearn as no setting was disturbed.

@@colinjoseph7276 thanks so much for your reply when you say cleaning can you elaborate on that thanks...😃

@@Unknown90010 use product brand CRC mass airflow sensor spray to clean the MAF & any throttle cleaning spray product specially for the throttle body.

@@colinjoseph7276 really I thought disconnecting battery will clear the ECU?

[@darring.9161]

Good Job...I just cleaned two of those today, the only thing I did differently was put in a whole New Gasket.

if the rubber doesnt feel soft ill replace it but im starting to see this issue more in toyotas then anything else

[@kappakool1911]

You have to reset the onboard computer first by disconnecting the negative battery cable for 30 seconds. That will turn the service engine light off. Then do the relearn procedure in the video.

[@kappakool1911]

The relearn procedure the first time I tried it after I reset the onboard computer by disconnecting the neg battery cable first. This temporarily turns off the service engine light. There's other videos that have 2 more steps to the relearn too

[@kappakool1911]

Also I have an, 05 Sentra

[@oceanenriqueplariza7393]

Is that a way to reset the ECU with a 2016 after cleaning out the throttle body?

@@kappakool1911 hi Daniel, can u please state those videos of the steps how relearn of this car.

[@JonFox1945]

Mine is like glued on, feel like I have to hit it with a mallet. Yes I removed the four screws. I don't think it's been messed with in a long time

[@NeutronX101]

Can you clean a throttle position sensor?

[@bcoronel01]

Is there a throttle position sensor on nissan sentra 1.8? if so, Where is it located?

[@uglyhp8225]

all vehicles with fuel injection have a tps if the vehicle has throttle cables its the sensor on the opposite side of the cables if its a electronic throttle body then its built into the throttle body and the whole thing would have to be replaced

[@Unknown90010]

I'm attempting to change this tomorrow for my 06 nissan where do I find the directions on a relearn procedure for this and is this needed for the car to work

[@uglyhp8225]

you can disconnect the battery cables and touch them together for about 10 min that will drain the system of any memories and it will do a relearn when you restart it sometimes it will run like crap for 10 min after doing this which is normal

[@Unknown90010]

@@uglyhp8225 ok thanks

[@rapidtransit8373]

You can look on youtube for your car. Then its throttle body relearn. There's a lot of them. Find one that will work for you

Can a defective of this affect air fuel ratio sensor ??

[@frankmontez6853]

I got mechanic to replace it on 06 Nissan Sentra 1.8L and it's still not fixed . A couple of things - 1) when I start it sometimes first thing in the morning or at lunch time at work it starts but won't rev up just stays low . No matter if I floor the pedal . 2) at red light tachometer revs up a lil over 1,000 and then dips down below that . 3) while running on the road in drive it again loses power can't rev it up . Any help will be appreciated

[@uglyhp8225]

yikes did he put a new one on or a used one also might wanna check the maf

[@frankmontez6853]

@@uglyhp8225 yeah he put new one. And check how the maf? By cleaning it? I'll try the simplest like relearn procedures and cleaning out the maf. You're talking about the air coming in from air filter right? It's got a electrical plug on one side of it.

[@michaelcrowers6628]

I just replaced the mass air flow sensor on my 05 sentra but it wasn't right so now im going to replace my actuator but your problem sounds just like a mass air flow sensor

[@frankmontez6853]

@@michaelcrowers6628 Took it to 2 shops . One changed out Throttle control sensor / body ( It's all one unit ) . It dies a couple months ago and found out fuel pump relay was bad so replaced that and pump still didn't work . Replaced pump and thought that was it . Nope . Started doing the same old thing not fully revving up even if I floored pedal . Now worse , rough idle even surging a lil at red light trying to push me past the braking .. seems it could be more than one cause ?? the pump was definitely not pumping and yet this wouldn't cause all the other problems would it ? Only a matter of time before it dies . friend said he knows of another car for sale .. It's 260k miles and it may be a goner . Tired of it being so hard to fix . Tired of mechs guessing with my money wasting it . Other things wrong with it , ;like one rear door won't open . Struts are gone and some locks are getting bad . Interior caabin lights too ..

[@frankmontez6853]

@@michaelcrowers6628 and lasst month finally took it to the dealer service dept and they found codes at TCB ./ sensor and with gas pedal / linkage . They said $700 on that repair and if that didn't work they try replacing harness for $650 . :Looks like they're just guessing

[@marionhale3391]

Awesome

[@frankmontez6853]

And no the scanner doesn't work on it. I've checked the fuses look good. The guy who worked on my car now recommends that I take it to a shop he knows has a big diagnostic computer and will cost maybe $75. Why didn't he tell me that in the first place?? Sheesh just to make a buck.

[@uglyhp8225]

yea sounds like he owes you a refund
