Hello!

I ran into a problem.
The EGT is connected to B6, if the output from the controller is idle at 1.42V, but the computer sees 3.8 - 3.9v. If I disconnect the controller from B6, then the voltage at B6 is 2.54V.

similar to a burnt diode in the ECU? If so, which one?

p28 + s300

Have you tried this on a known working ECU?

nope
all functions, all in/outs on my ECU work correctly, but pin B6 without EGT sensor is showing 2.5-2.8v

i was think maybe damage diode, but no diode on b6 wiring

Are you using just an EGT probe, or do you have a controller to properly read the EGT probe?

I use controller with probe. On controller out showing correctly voltage, on input b6 showing wrong voltage

i think IC5 is damaged
now i connect EGT to D12 - work fine
