Default 03 Touring Edition P0462

Here's the run down. Had P0462, mechanic put in new fuel pump. Then had to run new wire to power pump. Still have P0462. Have also put in new PCM with now change. Another issue that I don't think is related but who knows is radio works fine unless key is jarred out of cylinder even slightly then screen goes off and no sound out of speakers but you can still hear CD player as it changes dics. Push key back in and radio works perfectly.

P0462 - Fuel Level Sending Unit Low Voltage Conditions

Possible Causes:
1. Faulty fuel level sensor
2. Fuel level sensor harness is open or shorted
3. Fuel level sensor circuit poor electrical connection

The PCM has detected the fuel level as being more than 100% for more than 4.5 minutes and triggered the P0462 code.

I would suggest checking the fuel level sensor harness. Its a shame that when the wire was replaced for the fuel pump that the fuel level sensor wires were not checked at the same time. Physically check it from the PCM to the fuel tank and make sure its not rubbed through shorting to ground or open.
