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.

Can you help what does a po1698 code mean


I think this is a transmission code meaning the trans is not talking with the TCM. Does your speedo work? If no, could be a trans output speed sensor at fault, or bad connection.

My engine light is on, my speedometer sometimes works and sometimes doesn't register, some times it bounces back and forth.


code p 500 refers to vehicle speed sensor (VSS) --circuit malfunction====causes ---wiring---VSS sensor---ECM
the engine light reports serious faults with both the engine and the transmission
I would go to an accredited auto transmission shop and have the VSS replaced or checked
The VSS drives the speedo, cruise control,gear changes ( reports to the transmission control module (TCM)

- Crankshaft Position (CKP) Sensor harness is open or shorted
- Crankshaft Position (CKP) Sensor circuit poor electrical connection
- Communication error between the Engine Control Module (ECM) and Transmission Control Module (TCM)

The P0727 Codes is triggered when the TCM receives no signal from the ECM.
Possible symptoms

P0727 Description
The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Trouble code po700 dodge 1500


Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory. This illuminates the Malfunction Indicator Lamp (MIL) to let the driver know there is a problem. If this code is present and the MIL (Malfunction Indicator Lamp) is illuminated that basically means there is at least one transmission code set in the TCM's memory. P0700 is an informational code only. It doesn't point to a direct fault in the engine, only a general fault in the transmission. More diagnosis is necessary to identify what the transmission fault is. This requires a scan tool that will communicate with the transmission module.

PO500 vehicle speed sensor 2004 toyota sienna


VSS is in with the TCM in the transmission. If you have tyre pressure senders then the light is telling you of a malfunction in that area . ABS will not operate unless a wheel stops under brakes and then only that wheel receives attention from the ABS unit. So if you are on a hard surface road and braking normally there will be no ABS action at all. Under heavy brakes when the wheels start to skid you will feel a pulsation in the brake pedal and that is the indication that the ABS is working. You will in affect (when the ABS is working) take a greater distance to stop than normally expected.

PO888 and PO700 code


In the causes for po888 the main reason is sensor circuit malfunction with the wiring poor connection being listed. Check that the wiring connectors are free of moisture and that the pins are clean and tight. code p0700 is straight out TCM problem so again I would be carefully inspecting the wiring and connections at both ends
