A/C compressor speed sensor -G111-, (Zexel compressors
only)
Note: - Inductive sensor (4 pulses per compressor rotation)
- Determines A/C compressor speed; the A/C compressor clutch control
module (Manual A/C) or the A/C control head (Automatic climate
control) compares compressor speed to engine speed and calculates
belt slippage (as a percentage) and switches compressor OFF if
slippage is too large (for example, if belt is too loose.)
A/C compressor speed sensor -G111- is not installed on Nippondenso
compressors. A thermo-fuse is incorporated into the clutch coil of Nippondenso
compressors. Current to the clutch coil is interrupted in the event of
compressor overheating.
