Cadillac Repair: Trouble codes, cadillac deville, e98

Question
Hi, I have a 1993 Cadillac deville 4.9 v8 engine. I used the onboard diagnostic test and trouble codes E98 and F13 came up with E98 being first and F13 being last. What do these codes mean and how can I fix them and get rid of them?

Thanks

Answer
First CLEAR the codes from the computer.

Enter diagnostics until you see .7.0

Simultaneously push and hold the OFF and HI buttons until E.0.0 appears and release the buttons.

You will return to .7.0

Simultaneously push and hold the OFF and LO buttons until F.0.0 appears and release the buttons.

You will return to .7.0

Turn ignition OFF for 15 seconds.

Check to see which codes return.
