Codes were 661 and 663 and po705. They seem to have some reference to transmissions sensor that I cannot not interpret.

P0705 is a fault with the Transmission Range Sensor and can be due to a faulty sensor, its wiring or a bad PCM.

As to Code 661 and 663, I am not able to find ant reference to them. Are they OBD-II codes? Where did you get them from?

P0461, P0462 and P0463 are all related to the Fuel Level Sensor A circuit.

Is the fuel gauge accurate or acting strangely?

If not, reconfirm the trouble code. Go back to Autozone and ghet them to recheck the trouble code. After printing it out, reconfirm the codes are correct.

This code is not correct. Yours is an automatic trnsmission and this code is for a manual transmission clutch pedal position switch.

P0705 was explained to you previously, it is a fault with the range sensor, meaning the PRNDL switch.

Diagnostic test have to be carried out to determine what is wrong and a scan tool would make the job easier. Would you be able to perform testings with a DVOM?

How longcan I go before this problem gets worst. Right now don't seem to be anythng wrong other than the engine light is on after the scan removed the code and the check transmission shows up on the instrument panel. Not sure I understand what a DVOM test is. Thanks for your answering so quickly.

If an error has been detected, it is best to get it resolved asap. Any fault can damage the transmission if it is not taken care of. It is not possible to gauge how long before problem worsens.

It would depend on what is wrong. This component is a switch and first you need to check the wiring. Note if the wire harness connector is clean and secure first. Try wiggling th connector to see if it helps. Disconnect the connector and check for signs of contaminations.

Yes, that is the switch. Since the wires are brittle, there could be a fault with the terminals. You would have to disconnect the connector and check for contaminations.
