Kar Ser: I watched a youtube video on how to clean TB on my 07 Altima Hybrid. No one seems to mention on any forum Ive read so far, that the manual relearn will NOT work on 07 and newer models. Long story short, I took it in to Nissan for relearn, and $160 lighter, I was told I need a new TB. Ive orderd a Hitachi oem brand online (like anyone's going to pay nissans $790 TB). So after I replace it (NO, I wont dare clean/touch the buterfly again) I will have to dish out for another relearn to bring my idle under control..its idling very high after I cleaned/touched the butterfly. Any words of advice would be comforting at this time..i'm just really upset and finding it difficult to get over this....wish someone had posted a warning sign somewhere.
quantomic1106: HERE'S A FIX! To anyone who have this problem.
First, this is a very common issue with Nissan cars specially after servicing the throttle body or mass airflow sensor. This can also occur when the battery is drained or removed from the circuit. Therefore, DO NOT remove any battery terminals to fix this problem like many have said. Doing so will NOT fix the problem but just put you back to where you've started. Nissan released a bulletin for this and this is what you're suppose to do.
***Note: The timing within this procedure is critical, so get a stopwatch handy! Follow these steps to the letter! Trust me! It's easy, but can take a couple of tries.
Step 1. Drive your car around for at least 15min to let the car heat up to its operating temp and transmission to heat up as well.
Step 2. Park the car and make SURE that your gear is at "PARK" or "NEUTRAL'.
Step 3. Make SURE the steering wheel is centered.
Step 4. Make sure to turn off every electronic accessories ie, air conditioner, stereo, lights etc. If you have something like a phone charger in the cigarette lighter receptacle, remove it.
Step 5. Make sure all your car doors are closed and windows are up.
Step 6. Turn the engine off.
***Note: If you have anything that can obstruct the path of your gas pedal from being depressed all the way down to the floor, (such as an aftermarket carpet) move it out of the way.
Step 7. Turn the key to the "ON" position. Wait 3 second then back to "OFF" position for 10 seconds. (Repeat this step three times).
Step 8. Turn the key to the "ON" position again and wait 3 seconds, then FULLY depress and then FULLY release gas pedal 5 times WITHIN 5 seconds.
Step 9. Wait 7 seconds then FULLY depress and HOLD gas pedal on the floor until the "check engine" or "service engine" light start to blink for about 10 seconds.
**Note: The blinking should start within 20 seconds after holding the pedal. If not, stop the process and repeat the whole procedure starting from step 7.
Step 10. When the "check engine" or "service engine" light stop blinking and become steadily illuminated, fully release gas pedal and start the engine WITHIN 3 seconds.
***Note: if this procedure is done successfully, the RPM should go to spec (usually around 750 RPM give or take). If not, repeat the procedure starting from step 7.
Don't expect to get this down your first try! It took me at least 3 times till finally fixing the same issue I had :) A friend of mine took 5 times with his.
Hopefully this will help anyone who is experiencing the same problem with their Nissan.
Asif Mohamed: Just remove the battery for 24 hours and it will be fine
Curtis Channel: i think idle air control too
flashdkr: Had this same problem with my car. Before you take your car to the dealership make sure that if your doing the idle relearn you get the timing right. Timing is key for it to work. I had to do mine for several days till it finally worked. Also make sure your car is at operating temperature. Good luck
الشمري: Hi... it happened to my altima car yesterday..but today everything is alright... the car needs only computer programming.. the car electrician did it in less than 5 minutes.. it is the only solution.. greetings.
cisa93: If you haven't already been to the dealer, that's the only way to get this issue resolved. I hope you didn't just replace parts because a Nissan MAF is not cheap. As a 14 year Nissan/Toyota/Honda tech, it's the propriety software and many times a reflash of the ECU may repair this problem. Love Altimas but their MAFs and throttle body systems are too sensitive/ delicate if you choose to clean them. Take extra care not to touch the inside of the MAF and only use the correct cleaner. NEVER move the throttle plate/butterfly without key in "on" position. There is a "drive by wire" motor and it directly correspondences with the ISC unit/sensor. This applies to any of the types of throttle bodies. Best of luck
Jesse Montoya: It should be the idle air control.
Hitinder Bawani: Oh boy! I have same problem with my Altima. RPM goes up and down between 1000 and 2000, my car power was off while I was driving down the highway.
I hope you got your issue sorted out? Just today I dropped my car off at a local garage, the guy said car sensor needs to be replaced as well as they need to service throttle.
I am not sure if that's how you solved you issue? Do let me know how you sorted out your problem.
bettygood100: take it to a dealer. not all throttle bodies respond to a manual relearn
marlon aleman: ok i have 2006 nissan altima 2.5 tha idler problem , i change cranchaf sensor and culan sensor tha problem no more
Manuel Rivera: reprogram the throttle body, u need a scanner (Cj4) to fix it (or go to nissan dealer).
sthefan teran: I think you need to reprogram the ecu beuase it control the electronic throttle body or change the camshaft sensor.
david jasmin: My mazda 6 have the same problem when I change the throttle body and I do not know what to do
Julio Chavez: This happened to my Altima SE-R. I fixed it by doing the idle relearn, but not the regular idle relearn. It was another sequence.
Henry Polanco: Ran 9713. hou you fix you car i have the same problem? Dealers?
Henry Polanco: my car has the same problem. nissan altima 2006 2.5. How can i fix.....
Henry Polanco: mr car has thr
supadem: i have a 05. worst mistake of my LIFE buying it. JUNK CARS!!! headache from DAY ONE
Ran9713: most likely idle relearn. hook up the OBD scanner tool that you can borrow from Autozone or any other car part store for free, and note all the codes. Take it to the dealer and get an advice from them. I ended changing the Mass Air Flow Sensor (MAF) and the throttle body. You might have a bad cam sensor since these cars are prominent for that. Like I said, just hook up the scanner and get an expert advice from a real mechanic. They'll help you out
