MAP Sensor fail

---

Hi guys,

my MAP sensor is always readng -40 (i.e. faulty...?).

I've relpaced it with 1 new aftermarket and 1 used (but working...) sensor, so I believe is someting else.

I've cleaned with appropriate spray cleaner the loom, sensor side.

Where is the ECU side I should clean (I'd a bit reticent to unplug ECU...)?
There is something else I should look out for?
How can I test the cables are still good and signals pass?

Thanks
