Odd TPS

[paryoto.semesta]

Having problem with TPS.

It works normal when engine off.

TPS doesnt work properly when engine running.

All wirings seem fine, especially ground.

Any help would be appreciated.

Thanks

If i look into the log, i see that if your TPS voltage goes from 0,1 to 3,0Volt when engine is not running, but once your engine runs, you have TPS voltage 0,02 to 0,18V ...... so there will be no problem with EMU calibration.

I would look into the wirring, and measure ground, +5V and signal output.... There must be something "eating" the supply voltage or signal voltage when engine runs. May be also bad grounding of the engine....

Simply i dont think its Software or EMU problem, i believe its Wirring issue.

We have checked pin out B17, B18, B24, G17, G24 several times.

Move ground from engine block to head, vice versa.

Also switch/change TPS but problem still there.


"I would look into the wirring, and measure ground, +5V and signal output"

Which pin out number?


"May be also bad grounding of the engine"

Can you locate where to chcek for this?

Is it above pin out or something else?

Thanks
