Hi, I have a Hyndai Elantra and the engine light
Apparently so - P0501 is a speed sensor code,
The ECM will set a code and the Malfunction Indicator Lamp (MIL) will turn on if there is no vehicle speed sensor output signal for 20 seconds during two driving cycles when the following conditions are met:
Open between fuse and wheel speed sensor (WSS)
Open between WSS and GND
Open between WSS and ECM
Short to battery or GND between WSS and ECM
However, the other, P-456 is an EVAP system code:
Fuel filler cap loose or missing
Fuel filler cap o-ring missing or damaged
Faulty or damaged fuel filler pipe
Leaking, disconnected or plugged fuel vapor lines
Fuel in lines due to faulty rollover valve, on-board refueling vapor recovery valve or stuck closed CCV
Canister close valve clogged, stuck open or closed
Improperly installed purge solenoid valve
PSV stuck open or closed
Faulty fuel tank pressure sensor
Leaking canister or catch tank
If any codes relating to FTPS, CCV or PSV circuits are present, do all repairs associated with those codes before proceeding with this troubles area.
If DTC P0455 is stored and MIL is illuminated, before proceeding to evaporative system test and repair, verify whether the customer was running the engine during refueling.
If an obvious cause for DTC P0455 is an engine running during refueling, erase the DTC P0455 using Hi-Scan and do not repair the evaporative system. However, the vehicle should be monitored to find reoccurrence of the concern which may come from actual evaporative system.
