Description
Cirrus Aircraft 70551-001 Remote-Mount Oil Pressure Sensor Kit — SR22T, SB2X-79-04
On aircraft with the oil pressure sensor mounted directly on the engine block, long-term vibration works on the connector built into the sensor and the gauge begins reading erratically.
Cirrus classes SB2X-79-04 as recommended, on condition of erratic oil pressure indication — it is done when the symptom appears.
What the kit does: Moves the oil pressure sensor off the engine block, with the hoses, fittings and hardware to mount it remotely.
Why it works. The sensor is no longer bolted to a vibrating engine block, so the connector inside it stops being shaken — which is what produced the erratic readings.
Note: This kit is for SR22T aircraft in Groups A and B of the bulletin; Group C serials use kit 70551-002. SR22 aircraft use kit 70605-001 under SB2X-79-08. Refer to SB2X-79-04 to confirm the right kit.
