High pressure sensor -G65-, checking
Notes:
The presence of -G65- is engine dependant.
Where -G65- is not used, A/C pressure switch -
F129- is used instead.
Where -G65- is used, it's wiring circuit varies
according to engine application (E.g.: some are
connected to the ECM, some are not).
Always confirm system use of either -G65- or -
F129- and applicable wiring circuit using
applicable "Engine" and "Air conditioning"
wiring diagrams.
