DTC Description
OBD Status
P1172 A/F SENSOR (SENSOR 1) CIRCUIT OUT OF RANGE HIGH
Does the HDS indicate FAILED?
YES : REPLACE THE A/F SENSOR (SENSOR 1) , then do the repair verification .
NO : If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor
connections or loose terminals at the A/F Sensor (Sensor 1) and the PCM. If the HDS indicates
EXECUTING, keep driving until a result comes on. If the HDS indicates OUT OF CONDITION, go to
step 1-3 and recheck.

Is there continuity?
YES : Repair a short in the ELD wire between the PCM (A34) and the under-hood fuse/relay box, then
do the repair verification .
NO : The ELD wire is OK. Update the PCM See PCM UPDATE or PCM REMOVAL AND
INSTALLATION if it does not have the latest software, or substitute a known-good PCM See PCM
REMOVAL AND INSTALLATION or PCM UPDATE , then do the repair verification .
