This is the 40 bar Getrag clutch pressure sensor for both the odd and even clutches, one sensor for each. 2 (two) sensors are required per gearbox. Incorrect sensor operation can cause odd or even gear failure. The gearbox would begin skipping all even gears and reverse or all odd gears. Valve body gasket leaks can cause a clutch pressure fault as well. We recommend rebuilding the CCP completely. We have gaskets sold separately or CCP rebuild kits available. This Ferrari Getrag Clutch Pressure Sensor, identified by Part Numbers 70004021 or 70003860, is specifically designed for the 40 bar clutch pressure system.
It is crucial to accurately diagnose any faults associated with this sensor before attempting to remove the transmission from the vehicle. Potential faults associated with this sensor include but are not limited to:
P0841 – Odd clutch pressure signal invalid
P0842 – Odd clutch pressure sensor too low
P0843 – Odd clutch pressure sensor too high
P0846 – Even clutch pressure signal invalid
P0847 – Even clutch pressure too low
P0848 – Even clutch pressure sensor too high
P0933 – Hydraulic pressure sensor signal invalid
P0934 – Hydraulic pressure sensor too low
P0935 – Hydraulic pressure sensor too high
P1902 – APP_CLUTCH_PRESSURE_ODD, too high (odd shaft pressure command signal too high)
P1903 – APP_CLUTCH_PRESSURE_ODD, too low (odd shaft pressure command signal too low)
P1904 – APP_CLUTCH_PRESSURE_ODD, invalid signal (odd shaft pressure command signal not valid)
P1905 – APP_CLUTCH_PRESSURE_EVEN, too high (even shaft pressure command)
P1906 – APP_CLUTCH_PRESSURE_EVEN, too low (even shaft pressure command signal too low)
P1907 – APP_CLUTCH_PRESSURE_EVEN, invalid signal (even shaft pressure command signal not valid)
