Thank you. Shall I send you a longer duration video, Can you please spare some minutes to view it?
Short list the pids on following parameters only.
Engine speed O2s1 voltageO2s1 short fuel trims O2s1 long term fuel trim only.
Which app are you using to connect to it? I have vitz with 2sz fe and elm type devices failed to work on mine
I have the same engine.
I am using ANCEL iCar2 Bluetooth scanner and Motor Data OBD on android. Link is https://play.google.com/store/apps/details?id=com.motordata.obd
Thank you let me check if this works for me
Which obd device are you using
Elm327
And what's the production year of your car?
I tried but the app doesn't allow to select PIDs. It only gives all data. So kindly look at this 3 minute video please for fuel trims, O2 voltage, MAF values on various engine speeds.
Vitz 2007. The app is connecting perviously I tried it with torque pro but It didn't connect with ecu. One thing it isn't showing full parameters. It's only telling me dtc else it's telling me to purchase Toyota plug Inn
Torque never connects with many ECUs.
MOTPR OBD shoes pretty much a lot of parameters. Yes one will have to buy the Toyota plugin, but live data it is showing currently should be enough. But it gives all possible DTCs.
did you reset your ECU? how did the long term trim get to -3.9% by itself?
I did reset the ECU. The long term fuel trim got to -3.9% instantly after installing O2 sensor, new air cleaner assembly, servicing MAF sensor, servicing PCV valve and servicing throttle body (without taking it off).
Is this value good enough?
-3.9% is perfect
This is on idle.
Sorry to hijack your thread @ahmedstudio but @Xulfiqar I need your help Iam getting these codes and randomly the power steering dies while and indication of Gear like D or N goes away in meter and check engine light, power steering light and Abs turns on. Again this happens randomly
Please see the attached images for long term fuel trim values on various RPMs, engine load and speeds (I rev a lot, heavy foot). Are they alright? Also see the MAF values please.
drive the engine for 50 kms, then recheck the trim values - its a learned value. Do not reset the ecu.
The values I just shared are after driving for 120 km.
good - keep on driving it, its running proper at the moment. and please find a better tool - something that can graphically plot the o2 sensor.
