I have a 2007 c13 and check engine light flash one time what that code means?

Therre is no DTC code "5". The DTCs start at 12. If the knock sensor (there are actually 2) was bad, you would have an acceleration issue. The knock sensor changes the timing of the spark to eliminate detonation, or "pinging". Do you have a "Ping" condition/valve rattle on acceleration?
To reset the light, open the hood, remove the 15 amp EFI fuse for 5 minutes. Replace it, and start the car and drive it until it reaches operating temperature. If the light comes back on instantly, you have a bad sensor or a bad wire.

First check and make sure your gas cap is tight, if this does not resolve the problem read below.
A vacuum hose has become disconnected, more than likely due to having your air filter replaced. The VSC and Check engine light typically don't come on until after 150-200 miles after the vacuum hose was pulled out.
The fix: on the right-hand-side of the engine compartment behind the big plastic housing that holds the air filter you will find a black rubber hose that is not connected to anything. Squeeze the finger clamp on the hose and slide the hose back onto the half inch nipple on the back of the air filter's plastic housing.
In order for the VSC and Check engine light to be turned off, you will need to open the fuse box, right-side of the engine compartment, and pull the 20 amp EFI fuse for 10 seconds. This will reset the system. The fuse location is marked on the lid of the fuse box, also I believe the EFI fuse is the only 20 amp fuse

P0732 trans code, if this is a stand alone code, access someone with a chrysler scanner and monitor the trans speed sensors, preferbably the input one, make sure there is a rpm readings on both when you drive the vehicle, if ok, do a 2nd gear clutch test, if failed, internal clutch failure, if ok, replace the trans soleniod pack, it has internal failure, easy to change on this model with the 41TE trans only, if 62TE, take it to a Chrysler dealer.
GOOD LUCK, RDJRP
