This code is only the TCM (Transmission Control Module) telling the ECM (Engine Control Module) to turn on the check engine light.
If you don't have other codes there, could be a Communication Lost from the TCM; first I suggest to check all fuses and good harnesses conections correctly.
Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.
P1624-This Relates to throttle Pedal Position Sensor Potentiometer Supply Channel 1 Electrical .This is generic code info not based upon vehicle region,model or year.although it should not differ.So it is either wiring or sensor fault.Usually is the sensor.
Both codes refer to similar cause. the p1624 is saying that the engine coolant sensor is detecting a temperature lower than is required to open your thermostat even though the thermostat is open. There is a disagreement between what the car is reading as the engine coolant temperature and what you thermostat is responding to. The second code says that the engine coolant sensor is sending occasional higher than expected voltage readings. Both of the these codes together means that it is 90% a sensor issue and that either the sensor is faulty or the wiring to it is shorting occasionally (bad insulation). Find the sensor and wiggle the wires, unplug and plug the connector to it a few times and make sure the contacts are clean. If the problem persists change the sensor and/or wiring.
To check the thermostat pop it into a pan of hot water and at about 85C it should open. Take the pan off the heat and as the water cools the thermostat should be seen to quickly close again. It is unlikely to be the thermostat in this case.
P1624- Pedal Position Sensor Potentiometer Supply Channel 1 Electrical.
The Siemens MSE43.0 Engine mamagement module is used on more than one model. The different meanings of the P1624 are based on your model.
The P1624 referenced here is for the MS43.0 engine management module with a note for M52 engines (323 / 328) that it is a coolant temperature below thermostat regulating temperature. You should have a M52 engine.
The MS42.0 engine mangement does not list a P1624 code in the Bentley manual.
The fault above cold be set due to the following:· Break/open in the wiring from the DME to the throttle motor(MDK).· The actuator or potentiometers inside the MDK could be contaminated.SOLUTION: (If any of the faults listed are set) · Using a breakout box check for an open or short to ground in the wiring from the DME to the MDK.· If the wiring is intact then replace the MDK, then the adaptation values in the DME must be cleared. Failure to do this will result in reoccurring faults.· Switch the ignition off for 30 seconds.· Turn on the ignition and delete the DME adaptations and the fault code memory · Press the accelerator pedal to wide open throttle(WOT)4 times MDK- motor driven throttle valve.
p1115 is a coolant temperature signal from ECM to TCM. p1624 is MIL request from ECM to TCM. Did the vehicle overheat? If so check the temperature sensor and the thermostat. Some vehicles will overheat and shut the engine off until the computer is reset. But with both codes involving the same computer modules the best bet might be to rescan the computer and reset it. Both modules might need to be changed.
Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.
Code number p1624 is MIL Request Signal from TCM to ECM. which means malfunction indication light(MIL) is requesting a signal from your engine control module(ECM) or Transmission control module(TCM) i would reccomend u take it to the dealership to get it checked out.
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
Code P1624:M52 coolant temperature below thermostat regulating temperature. Check the temperature of the coolant and also with a scan tool, check the actual reading given by the coolant temperature switch. It could be the thermostat or a coolant sensor.Look also for any broken/corroded wires to the sensors as well.
