Ecu only se 10-14mv from lambda

Post by miler »

Im useing s80pro and innovate mtx-l lambda
Now the ecu doesnt see more then 10-14mv
I measure 5v going to it.

My ecu screwed ?

It probably isnt either wired correctly, or configured correctly.

So no, the chances of your ecu being screwed is very slim....wiring/configuration screwed...very high.

And you measure 5v going to what ?

Ecu is getting 5v from the gauge i measured that all the way to ecu
And a couple of days ago it did read more because i had 4996 recorded as highest in diag.and i did reset diag when i switched to dizzy.

Are the Sensor 0V referenced together? e.g. the 0V for the lambda output and the sensor 0V in the DTA

There are almost no circumstances when an Innovate will output 5v.

Exactly how do you have the MTX configured ?

I wired the ana output (0-5v from Gauge
To lambda input at ecu
IF iturn ign on the gauge shows Afr 22.4 and send out à 5v signal
Once warmed up.
Starting the engine volts go down just as it supposed to

How do i reference them ?
Shouldnt the ECU see the voltage anyhow?

So when you program the output on the MTX to different voltages, are these read correctly on the DTA ?

And likewise, from a test source if you apply a voltage to the DTA input, do you get a reading ?

you could either just fire 5v into it or say hook it up to the TPS signal just to verify the input works.

Need to update . Its solved :)
Strange error was found in the pin .
5v in the rear then random volts thowards front.
Replaced it now all good.
