Note that the same barometer is used in PPC3, RPM4, PPCH, PPCH-G and newer models of PG7000/PG9000 with version 3 firmware and above from August 2008, SN 733 and above.
If you suspect the on-board barometer in a PPC4 is faulty, do the following:
Error code: Baro Sensor err: $01
PPC4 internal barometer PN
|3126355||401898-06,ASSY,BAROMETER,100K NOVA (DWG U03634)|
At the bottom of the screen, please note the internal barometer reading, is it changing if you put your finger on the ATM port in back, or is it stuck at a number? If stuck on a number or not reading, the problem is likely the barometer.
1. Using the manual, remove the cover.
2. Using the figure below, remove and replace barometer assembly. This is a plug-n-play function.
