Not getting 5 Volts to MAP

[Hawmps]

Hi everyone,

I've been trying to chase down why it am not getting a MAP sensor signal and I have traced it with my multi-meter to not getting 5 volts from the ECM to the MAP sensor. I am looking for some suggestions on where to look next to see why I am not getting power to the MAP sensor.

2002 Tahoe, 5.3L LT 4x4, lots of miles.

Many thanks in advance.

Your ecm might be bad. You can try a new map sensor. But if your sensor isnt getting 5volts than buy a refurbished ecm.
