Sensor P1 or P2 (Fig. 2.29) can be assembled on the
engine:
P1 Characteristics indicated in Tab. 2.33A (blue connector).
Thermal contact N/O with closing temperature at +110 °C
±3°C, re-opening +88 °C / +100 °C.
P2 Characteristics indicated in Tab. 2.33B (white
connector).
Thermal contact N/O with closing temperature at +110 °C
±3°C, re-opening +88 °C / +100 °C.
NOTE: R indicates the pin where it is possible to measure
