OBD2 Scanner TPS sensor below 30% at engine ideal

[U-tag]

මචං මාගෙ Alto K10 එකේ TPS percentage එක 25% level එකේ තියෙන්නේ RPM 1,400-1700 වගේ තියද්දී (ideal).

මෙක normal ද? මම දැක්කා 50% වගේ තියෙන කතාවක්.

Update!
RPM corrected.

මේක බං Alto K10 VXI - 1,000CC එකක්. 2,000 එන්නේ නම් නැ බං. Ideal නම් එන්නේ 1,400 - 1,700 වගේ.

ඔව් බං. Normal temperature එකේ.

STFT එක -18.8% සිට -14.1% වගේ තිබ්බ.
LTFT එක දිගටම -13.3% වගේ තිබ්බේ.

89°C තිබ්බේ ඔය STFT data ගන්නකොට. 54KM දුවද්දී max coolant temperature එක 91°C තිබ්බේ. App එකේ History එකේ 98°C ගියපු අවස්තා තියනවා.


මේ max coolant temperature එක ආපු අවස්ථාව.

Why O2 sensor going up and down ? fuel burn wenne nathi seen ekakda ? Maybe one of then cylinders not burning correctly. Check ignition and plugs.

Negative Fuel trim means cutting fuel at injectors , could be an air leak ? O2 sensor maybe dirty ?

If it idles at high rpm means throttle is compensating for something. Maybe at 600-800 knock sensors detecting something? Again leads to at least one cylinder not burning correctly?

does the engine vibrate ?

Upstream O2 sensor voltage should be going 0.1v to 0.9v as the graph. But, in this case one cylinder seems running rich.

if there’s an air leak, it should run lean. Means ECU will add more fuel
