I’ve experienced my MP sensor reading high. After several attempts to recalibrate it in the aircraft with tech support I’ve had to return it to GRT for servicing and recalibration.
Here’s my plea. Builders please think seriously about long term servicing issues during your build. The original builder (I’m the second owner) installed the MP sensor under the panel in a near impossible to reach location. Additionally he didn’t leave enough wire nor manifold pressure tubing to relocate the sensor. I’m pretty sure (from talking to a builder friend) the original owner probably installed the sensor when he was installing the panel and before the panel cover was installed.
I had to have a young flexible individual, after removing the CP stick, seats and center console, spend approximately four hour upside down under my panel twisted in an unbelievable position to remove the two bolts and nuts thatt attach the sensor to the panel’s frame. Unbelievable! I’d cuss the builder but he’s has already passed away.
So please consider long term servicing when make build component placement and attachment decisions. Use nut plates as much as you can - especially where access is limited. Avoid locations that require people to be a contortionist to access or at least install access panels. Plan ahead!
