Here is the definition for the code.
You may need the dealer or a shop to check it out.
P1614 HYUNDAI Description
There is a communication line between Powertrain Control Module (
PCM) and Electronic Throttle System (ETS) unit. Using this communication line, various data, such as throttle target angle,
TPS output, APS output and diagnostic trouble codes regarding ETS motor,
TPS and APS are communicated between
PCM
and ETS unit. A malfunction is detected by using a checksum technique
for verifying data. The digital data is composed of zeros and ones. A
checksum is the total of all ones in a string of data. By comparing the
checksum value with a stored value, a malfunction can be detected.
Possible solution- Powertrain Control Module (PCM) harness is open or shorted
- Faulty Electronic Throttle System (ETS) unit
- Faulty Powertrain Control Module (PCM)
