Narrative: When I arrived in the morning the aircraft had MEL 76-XX-XX on the plane; thrust lever position sensor for #2 Engine. After the Captain looked at the logbook and checked [that there was] no open write-ups; I doubled-checked his work and [the aircraft's] airworthiness [and] determined [it] was competed. [I] looked up the MEL in the MEL-CDL-NEF manual and checked that all conditions were met; which they were. Flew up to EUG with no issues.Coming back to ZZZ; we were cleared visual XXL and about ready to intercept [the] localizer and glide slope; when the #2 Engine rolled back to idle power. Along with the roll back of engine #2; [we] got ECAM ENG 2 THR LEVER DISAGREE. [The] Captain asked to cancel the approach; being outside the FAF - and also to give us time to figure out what the issues was. We [requested priority handling]. [We] ran the ECAM; followed by [the] FCOM to review any other information. [We] checked [the] performance along with [the] QRH one engine inoperative straight-in approach. Thrust Lever Two was unresponsive to any inputs and engine stayed at idle thrust. [We] briefed [the] flight attendants for yellow emergency along with what was going on and time remaining. [We] briefed [the] passengers saying we had a thrust lever or throttle that was not responding correctly; we ran the checklists and we will be landing shortly and I appreciated their patience. Landed without any further issues and taxied to the gate. As of today I found out that Maintenance applied the wrong MEL to the aircraft. Preventing measures would include double-checking all of Maintenance's work more closely. But I do not have all the information. I do not know the fault codes that they see and what path those faults may take them down [to] or what their troubleshooting checks look like. It is hard; if not impossible; to determine the course of action they take to a write-up and if it's correct or not. As pilots; we rely on Maintenance Control to implement due diligence when implementing an MEL.




Synopsis: A319 First Officer reported that an incorrect MEL was applied to the aircraft and resulted in a loss of power to engine while on approach for landing.
