Re: new cel help please

If transaxle DTC are set and the MIL is illuminated, codes P1624 and P1529 will be displayed in the "Engine" menu.The purpose of the DTC is to advise that the TCM requested the ECMto turn on the MIL (the TCM does not have the authority to turn on the MIL).
P1624 MIL-On request from TCM
p0717
DESCRIPTION:
An improperly functioning pulse generator on a 1996-2000 Elantra, 1997-2001 Tiburon or 1996-2002 Accent may result in the following conditions:
NOTE
These conditions may be intermittent and difficult to duplicate:
Diagnostic Trouble Codes:
P0717 - No pulse generator-A signal
P0722 - No pulse generator-B signal
P1624 - MIL-On request from TCM
-Third-gear "Fail-Safe" condition and/or "Check Engine" light on
-Harsh, delayed or erratic 1-2 upshift
-Harsh or erratic 2-1 downshift during light acceleration
-Vehicle bucking and/or hesitation
REPAIR PROCEDURE:
Check for DTC in both the Engine and Automatic Transaxle" menus. If you have the following DTC, perform the repair procedure:
DTC REPAIR PROCEDURE
P0717, P0722 Replace pulse generators
P1624 Erase code
P0732, P0733, P0734 Erase codes: (P0732, P0733, P0734 may be induced by animproperly functioning PG-B)
Clean both ends of the pulse generator connectors and the connectors to the TCM with aerosol electrical contact cleaner such as:
NAPA Electronic Cleaner, P/N 765-1843 or
MOPAR MP-50 Electrical Contact Cleaner, P/N 04549626 or equivalent
Reconnect the pulse generator connector. For 1996-2000 Elantra only, remove the connector from the transaxle bracket. Leave the connector loose on the transaxle case to prevent any tension on the harness.
Test drive the vehicle for at least two key-on to key-off driving cycles:
If P0722 recurs, go to Step 5.
If P0717 recurs, go to Step 6.
For 1996-2000 Elantra or 1996-2002 Accent, replace the reed switch on the speedometer. For 1997-2001 Tiburon, replace the vehicle speed sensor on the transaxle. Test drive the vehicle for at least two key-on to key-off driving cycles:
If P0717 or P0722 recur, go to Step 6.
Replace the TCM. Test drive the vehicle for at least two key-on to key-off driving cycles. If P0717 or P0722 recur, go to Step 7.
Replace the wiring harness between the TCM and pulse generators:

Check the transaxle range switch
Check the transaxle range wiring harness
Check the manual control cable
--------------------------------------------------------------
Not being a Hyundai Tech, I would guess the first thing you want to check/replace is the pulse generator, and then the range switch. Could also be that your wiring harness if fvcked up... It can get expensive quick if you don't know what you're doing, you might be better off getting it to a dealership... Maybe someone else has some insights...

Good luck...
