MAP Voltage and others

[Bremsklotz]

I like to make the "Diagnostic Circuit Check"

Ther are a lot of Units would shown on the Tech 1 that i cant find in ElanScan.

Example "Fuel Integrator"
or "Block Learn".......(perhaps Flags 20- bit7?)
or "MAP Voltage"
or "Sync Pulses"

I think they are under "Flags" and not named. But i dont find.

I tried to check the 5V For the Map directli on the ECU, but i found no Signal. Its difficult to get in with the Checker.

As long as Elanscan shows MAP around 1 bar in a straight line with ignition on but without the engine running, I would be quite confident that the MAP sensor is okay.

True. But i try to follow exactly the Diagnose Charts and there they want to control pressure and Volts. With the "should be okay" the car still not running. i must now work with system.

Well it's up to you. I would not concentrate on diagnosing an okay MAP sensor, though.
