After turning base; we were given a speed of 170 KIAS. Once we had slowed and were about to make our turn to final; the number one engine didn't spool up again. An ECAM alerted us to a discontinuity between the position of the thrust levers and the thrust selection sent to the FADEC (number 1 Thrust selection was indicating idle while thrust lever was in the climb detent).  After referencing the QRH and the A320 landing app; the Captain elected to continue the approach and we landed without incident. Thrust lever position sensor failure.
On base about to turn to final; ECAM warning 'ENG 1 THRUST LEVER DISAGREEMENT'. Performed ECAM procedure; First Officer continued the approach and landing with the number 1 engine at idle due to number 1 thrust lever being unresponsive to power settings. The Thrust Level Angle (TLA) indicator dropped to the bottom of the EPR gage.Failure of TLA indicator sensor; obtained from post flight report.
After slowing for the final approach at 4;000 feet; an A320 ECAM alerted ENG 1 THRUST LEVER DISAGREEMENT. The ECAM procedure was completed and the approach continued with the engine at idle. Maintenance found a failed Thrust Level Angle (TLA) Indicator Sensor.
