2007 Kia Carens [continued]

[seymorebutts]

Sir ano na balita?

ganun pa rin pero hindi na ganun ka obvious yung pag hesitate nya but i still feel na meron, tried changing air filter but same same.

does this concludes na whenever our battery dies e nawawala yung update? like also what happened to you na na-clear yung error but nung nagpalit ka batt e bumalik ulit? and we have to pay Php 1,xxx.00 for the ecu update service?

sir, I got this from a forum post (by mustang67408) from the URL :
How, EXACTLY, does the ECU work?

The ECU "learns" about your engine as you drive the car. The "learning" is actually a process that the ECU uses to track the tolerance changes of the sensors and actuators on the engine. Two examples of these values are the position of the idle-air bypass valve (automatic choke) at idle with the A/C on, and the trim gain on the injectors. The ECU stores these "learned" values in battery backed-up RAM so that it doesn't have to start from scratch the next time you turn your engine over.

"Resetting the ECU" is the process of clearing all the long term memory from the ECU's memory. These variables trim idle speed, fuel, spark, and more. The ECU will also store trouble codes for diagnostic capability. By resetting the ECU, the trim values will be set to some neutral default value and all of the trouble codes will be cleared.
How-To

To "reset" the ECU, all you have to do is remove the source of backup power. To keep the memory alive while the car is off, the ECU has a direct line, through a fuse, that goes right to the battery. This is usually the same line and fuse that supplies backup power to your radio so it doesn't forget all of its settings. Your ECU has now lost all of its long term memory values and will "reset" them all to defaults when it next powers on. By the way, the factory radio's memory lasts for a minute or two, so you probably will not lose your saved stations.
Myth

There is quite a bit of mythology revolving around resetting the ECU. Many people mistakenly believe that they need to reset the ECU after installing major engine modifications. Others believe resetting will resolve engine problems. Neither are correct.
Reality

The ECU is always tracking the engine's sensors and actuators. Resetting the ECU does not cause the ECU to learn engine changes any faster. The ECU is always tracking the gradual changes in the engine sensors and actuators. The ECU never gets satisfied with a setting, and is always updating the trim values. It will discover whatever change you made to your engine and make the appropriate changes. In fact, unplugging the ECU will most likely increase the learning curve of the new part.

There are only two reasons why you would want to reset your ECU. One is to clear a CHECK ENGINE light or error code after fixing the problem that caused the error. The other is to reset the spark advance trim value. The advance trim controls how much the timing is retarded from what the factory engineers considered optimum. This particular trim value is the only one the ECU "resets" to a non-neutral MAX value. If you are driving on low grade gas, the pinging picked up by the knock sensor causes this trim value to be lowered, and your timing to be retarded. If you go to the track and put good gas in the tank, you might not want to wait for the ECU to learn about the new gas and advance the timing. So resetting the ECU in this case makes sense. However, in the process, you will lose your idle and fuel trims (probably not too important for drag racing, though).
Questions

Won't clearing the trouble codes make the car run better? If the ECU notices a problem with a sensor, it will flag a code and possibly turn on the CHECK ENGINE light. Should the problem go away, the ECU will turn off the light and start using the sensor as normal once again. The code will be stored inside for later diagnostic retrieval. But that code being stored does not affect the ECU operation in any way.

I reset the ECU, and now the car runs rough! Why? The engine may run rough or idle poorly right after ECU reset. The ECU now has default numbers in its trim memory - it has to adjust them to match the tune of your engine and its sensors and actuators. It might take a day or two of driving in traffic before the engine will settle down again. Now you know why the ECU remembers these values in the first place!

Hope this helps

HTH although there is no way to verify this at the moment..

thank you sir for that info, wala pa kasing time to go to kia pampanga e kaya nag iisip ng "possible" cure

agree po ako d2 about ECU learning process. Halata talaga everytime the gas tank is refilled, lalo na kung ibang gasoline grade & brand. Ramdam ang changes sa hatak & response right after tank is refilled. Sunod na araw ok na rin ang response ng makina...

Just had two repairs done to my 5-yr old Carens EX last week at Kia Sucat.
1) Air bag indicator was always on. Probable cause daw was trying TOO HARD or forcing to straighten the steering wheel in locked mode. A spring broke and a part assembly had to be replaced.
Parts & Labor = P4851.78.
2) Aircon sometimes did not work. Diagnosis was magnetic clutch was working only at 20%. Replaced Field Coil, compressor oli and freon.
Parts & labor was P5807.31.

Total repair cost less 5% discount plus 12% VAT amounted to P11,341.27.
So far, I'm satisfied with work done which has a One (1) year warranty.

Kaya siguro advisable pa rin na magstick sa isang fuel brand, grade, at rating..

Just left my carens for 40k pms today at kia pasig, cost is 15,544.40

Sir, what is the scope of work of your 40k pms? palit lahat fluid?

[Kape]

38,000+ KMs and almost 5 years later ... I will have to let my Carens LX AT go. Any idea magkano ang Carens natin sa market ngayon? Ayoko sana but farm roads in the province will not do my Carrie good.

Hi Retz, ito ung quotation. Nakita ko nga ung post mo sa innova 40k mo, hinanap ko to compare, mas mahal ng 25% halos sa carens.

[Retz]

^

Nabasa mo pala un sir. Mahal ung fuel filter and transmission fluid. Ilang liters un engine oil ng Carens? namamahalan na nga ako sa PMS ko, mas mahal pa sayo.

7 liters, hassle nga nasabay pa brake pads at head light

di ba 6liters lang? what about the headlight sir? grabe presyo nyang air filter ah

[dodongo]

di ba 6liters lang? what about the headlight sir? grabe presyo nyang air filter ah

All in all lumabas 14,463. headlight mga 850

fuel filter- 2,200 php???...what type of filter is this???..I changed the fuel filter of my 1st gen tucson, cost 600 php (if I remember it right but for sure not over 700 php) in goodgear.

nagulat nga din ako sa price ng fuel filter sir. mahal pala mag pms sa kia pasig.

[dodongo]

nagulat nga din ako sa price ng fuel filter sir. mahal pala mag pms sa kia pasig.

Ito yata same sa sorento and i assume same lang sa tucson? Picturan ko later. Grabe palatagang-taga kung same nga talaga ito

Fuel, Oil, Air and Aircon-Cabin filters are different types and the fuel filter is the most expensive and replaced only after 30-40K kms. You can save lot (more than P1500) if you buy from Goodgear.

Guys, anyone knows the part number of the driver door electric lock actuator is? Had mine checked at our local Kia Casa and they told me that it needs to be replaced and it costs roughly 7k plus around 2k labor charge. I thought that it's too much and asked for the part number and got a "sir, our company policy is not to give out part numbers". What a load of crap! I need to mail order one now since I can't source one locally, called up seiring but was asked the part number to make sure.

[crichton]

nakuha ko today antenna na order ko. 1 month ding pagaantay. mahal kasi sa casa kaya sumugal na ako sa ebay. laking mura...
