Got a 98 honda accord lx 4cyl auto. The codes are P1706 and P1457. The P1706 says that lockup clutch does not engage probably cause open or short circuit condition in gear selection switch circuit. Poor electrical connection. Failed gear selection switch. WHERE IS THIS SWITCH LOCATED I GOOGLED AND IM RETARDED AND STILL CANT FIND IT!!! and the p1457 emission control system leak detected ( control canister system ) probably cause lose fuel cap. vapor canister saturated, failed vent solenoid, failed purge solenoid. WHERE IS THE VAPOR CANISTER VENT SOLENOID AND PURGE SOLENOID?!
