Your transaxle is the transmission. The TPS is the throttle position sensor. ECM is the is the engine's computer. The TCM is the transmission computer. So, the throttle position sensor is not reporting to either and needs to be replaced. They seem to be about $180 for the part.

I have these codes reading now po700 po335 and po727 any idea what to check first on 03 kia sorento. my car lost power then shut off, then wouldn't start

p0335 is a crank shaft sensor error. This sensor is what tells the ECM when to send spark to plugs. That is why it wont start.

Code po320 and code p1631

The Code 1631 is for no Alternator output. The Code 0320 is for a lack of power in the ignition coil circuit. Means the ECM is not recording a signal from the igniiton coil path. The coil path means the crankshaft sensor, the camshaft sensor, etc. Basically no power is going through the wires to reach the ECM.

I have a 2006 Kia sorento had an oil change a couple days ago but now the car is revving highly and has problems shifting in 3rd gear and pass what could be wrong

Its reving high,like pressing on the fuel,and the RPM just shoots high,you are describing a sliupping transmission. Kia has problems with shift hesistation dealing with the TPS, get that troubleshooted first if its not the TPS you are dealing with a VSS(vehicle speed sensor ) if both component are not at fault the solution is another transmission or rebuilt

Code P0700

P0700 = TCU request for 'MIL' on (IE transmission control unit has detected a fault and wants you to know about it.)


A communication line exists between the Engine Control Module(ECM) and the Trans-axle Control Module (TCM). The sole purpose of this communication line is for the TCM to notify the ECM to activate the Malfunction Indicator Lamp (MIL) when a serious trans-axle failure has occurred.

DTC Description
If the signal "MIL ON" is requested from TCU or it is no signal from TCU, the ECM judged as a fault and DTC is set.

Kia's first suggestion is to check for damaged wiring or connectors.

Try this: Disconnect your battery for about 5 minutes to clear the fault. Then take it for a spin and see how it shifts... good luck.

How do I repair the P1121, TPS on a Kia 2004 Sorento?

The Throttle Position Sensor (TPS) for Sorento & Sedona models. Some Sorento & Sedona vehicles may exhibit diagnostic trouble codes P0121 and/or P1121. This condition mainly occurs in high ambient or desert areas, and can be related to the occasional increase in contact resistance due to excessive wear of the inner elements of the TP sensor. This bulletin describes the proper service and adjustment procedure for replacing the TP Sensor. - Service Procedure Replacement Procedure: 1. Turn ignition OFF. Remove engine cover and disconnect electrical connector from TP Sensor. 2. Remove two (2) retaining screws from TP Sensor and remove from throttle body. 3. Install new TP Sensor to throttle body. Install retaining screws and hand tighten lightly. Adjustment will be required. Re-install electrical connector to TP Sensor.

Got a code p1624 on my 2000 kia sportage with is it and what does it do.

Per the manual it states: MIL Request Signal from TCM to ECM. Which means there is a signal fault between the Transmission Control Module to the Emission Control Module. If you can, take it to the dealer for repair as they have the parts on hand and are most familiar with their vehicles.
Good luck to you

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
