saya dah cuba, serius berkesan. berdebar jugak tunggu rpm naik. takut tak jadi. tapi ternyata memang berkesan. NCP93 dugong. tq atas ilmu yang tuan beri.
Actually none of these steps really work ( like pressing accelerator x3 times or x10 times ). After repalcing battery on your vios NCP93, the timing will usually shows a very low RPM, sometimes below 500 and the engine will rough idle and die off. But don't panic, just restart your car, gently press on the accelerator and hold it at 2500 - 3000 rpm for about 5-10 mins, after that the RPM will comes back to normal again. I always do this for my vios after I replaced the battery. Apparently the same happen to toyota camry as well, not sure why the ECU lost track of the stored RPM after battery change.
The TPS setting will reset when the battery is disconnected cause small openning of IACV. If there are gunk inside the IAVC andbbutterfly valve with TPS reset, the actual airflow openning is much smaller then it should be. Do a throttle body & IACV cleaning should solve the issue of low RPM after battery replacement.
Ada pomen ckp naik je 2 3 hari nt dia naik normal balik... Aku siap pegi tune balik abis 60 inggit xjd ape last2 dia naik normal sndri. Tq bos. Bg ilmu
