After cleared approach and slowing for landing configuration a Lo Oil Press #1 engine appeared on upper ECAM with no caution or warning light or aural alert. Engine page showed approx 45 PSI in amber band and oil quantity was normal as were all other engine indications. Oil pressure intermittently returned to normal range of 210-220 PSI indicative of a sensor problem. Approach and landing continued uneventfully.  Eventually oil pressure entered red band and engine was shut down after landing. QRH consulted but only leads to post engine shutdown approach procedures while airborne.  Entered observations into AML and maintenance subsequently removed aircraft from service. QRH is vague for this condition. Phase of flight did not allow for extensive review.
A321 Captain reported a #1 engine low oil pressure indication on the upper ECAM display and elected to continue the approach to landing; subsequently shutting the engine down after exiting the runway.
