Narrative:

We were cleared 070 degrees to intercept runway 9R localizer at ord. Captain briefed approach and subsequently selected the localizer for runway 9L. I noticed ILS DME was not coming in so stayed on ord VOR for DME. I did not check captain's selected frequency or attempt to identify (as I normally do). Captain's localizer was captured and I saw a runway at 12 O'clock. Ord approach called to say 110 degrees to intercept runway 9R. I responded on localizer and approach responded localizer frequency 111.1. Captain set correct frequency, intercepted and landed. Approach said later was no conflict. Captain said approach book was open to runway 9L and runway 9R, got localizer frequency from wrong page. Captain did not identify localizer as is required per operating manual and company policy. I should have idented (as backup to captain). I might have seen runway as wrong runway (visually) earlier, too. Lack of DME on original frequency should have been a clue also. Maybe having approachs to parallel runways as consecutively numbered (and opposite each other in approach book) contributed.

Original NASA ASRS Text

Title: CAPT AND PF TUNES IN WRONG ILS FREQ AND IS ALERTED TO ERROR BY THE TWR.

Narrative: WE WERE CLRED 070 DEGS TO INTERCEPT RWY 9R LOC AT ORD. CAPT BRIEFED APCH AND SUBSEQUENTLY SELECTED THE LOC FOR RWY 9L. I NOTICED ILS DME WAS NOT COMING IN SO STAYED ON ORD VOR FOR DME. I DID NOT CHK CAPT'S SELECTED FREQ OR ATTEMPT TO IDENT (AS I NORMALLY DO). CAPT'S LOC WAS CAPTURED AND I SAW A RWY AT 12 O'CLOCK. ORD APCH CALLED TO SAY 110 DEGS TO INTERCEPT RWY 9R. I RESPONDED ON LOC AND APCH RESPONDED LOC FREQ 111.1. CAPT SET CORRECT FREQ, INTERCEPTED AND LANDED. APCH SAID LATER WAS NO CONFLICT. CAPT SAID APCH BOOK WAS OPEN TO RWY 9L AND RWY 9R, GOT LOC FREQ FROM WRONG PAGE. CAPT DID NOT IDENT LOC AS IS REQUIRED PER OPERATING MANUAL AND COMPANY POLICY. I SHOULD HAVE IDENTED (AS BACKUP TO CAPT). I MIGHT HAVE SEEN RWY AS WRONG RWY (VISUALLY) EARLIER, TOO. LACK OF DME ON ORIGINAL FREQ SHOULD HAVE BEEN A CLUE ALSO. MAYBE HAVING APCHS TO PARALLEL RWYS AS CONSECUTIVELY NUMBERED (AND OPPOSITE EACH OTHER IN APCH BOOK) CONTRIBUTED.
