1.
Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage. 2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.Possible correction/solution: Disconnect the battery cables from the battery and touch them together 30 seconds, then reconnect them to the battery - if the problem is 'garbage' in the ETS memory module, this will clear it. If not, then I'd say most likely the malfunction code is accurate and you need a new module OR, get an expert to VERIFY the code's accuracy.

In regards to the 1614 code. You should/could also see code 1610.

P1610/P1614
P1610- Ignition key/engine control module (ECM) malfunction
P1614- Immobilizer control module (ATS) coding plug communication-no signal. (ATS=anti theft system)
The ECM is getting a signal form 1614 that the key/ignition is not providing a correct code. Hence, the programing is told to fail engine start. Should the engine failing to start with 1 key, try the other key.
Should the Anti Theft System go into lock mode with one key, try the second key. If that does not unlock it then do this: with either key turn the ignition to ON position for 5 seconds then BACK to OFF position for 5 seconds, the to On position for 5 seconds then back to the OFF position for 5 seconds. If the ignition key is and intergrated key (remote: unlock, lock) the batteries should be changed in both keys. Low battery or dead battery provides low or no security code signals to ECM -- hence incorrect or no signal.
When replacing the batteries: be sitting in the drivers seat with the 2 keys within 24 inches of each other. And make the battery change within 1 minute for each key and within 4 minutes of the first key.
If that does not work,Check you users manual for the ignition key sequence on/off series to relearn the on board car computer to the keys.

Hyundai Sante Fe sputters and will not excelerate pass 40 to 45 miles for about a minute. Then will pick up speed. This occurs about every 6 or 7 weeks. Seems to happen after I stop. I have a 3.5 engine...


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)

Locking the trans in 3rd gear every now and then


Check Engine Light? When a 'check engine light' (MIL=Malfunction Indicator Lamp) is turned on, there is a DTC (Diagnostic Trouble Code) set/stored in the ECM/PCM (Engine Control Module/Powertrain Control Module). This code identifies which engine management system component/function experienced a malfunction. Once you pull/read this code, you may begin diagnosis.

Check engine light is on and my car hesitates when accelerating. Sometimes the check engine light will blink (instead of just stay on steadily) during moments of hesitation/acceleration.

Trans range sensor circuit malfunction


Transaxle Range Sensor Circuit Malfunction (PRNDL Input).  

Check for: _ Possibly a connector near the shift lever has come loose/dirty contacts, or there is a broken wire from it somewhere going to the TCM 
- Corroded or faulty Range Switch. - Open between Meter Fuse and Range Switch (C136-4).
- Open between Range Switch (C136) and TCM (C229) on one or more circuits. 
- Short to Battery between Range Switch (C136) and TCM (C229) on one or more circuits. 
- Short between two or more wires between Range Switch (C136) and TCM (C229). 

If Meter Fuse is blown, repair any shorts in the Meter Fuse circuit.

P1624 MIL Request Signal from TCM to ECM.This is only a request from TCM to ECM to turn the MIL on. The fault code is stored in the TCM.The Freeze Frame Data is stored in the ECM under the P1624 request code. Be sure to retrieve freeze frame data before clearing code P1624 from ECM. 
TCM = Transmission control module 
ECM = Engine control module (or more commonly known as ECU) 
MIL = Malfunction indicator light (more commonly "check engine light" or CEL) 

Good luck and hope this helps
