2003 Nissan Sentra P0462 and U1001 Codes: O/D Light Flashes 17 Times, Service Engine Light On
My 2003 Nissan Sentra has recently developed several gauge issues, with the overdrive (O/D) light flashing 17 times. After refueling, the Service Engine Light came on and remains steady. The vehicle is now displaying diagnostic codes P0462 and U1000. This is the first time I've seen the engine light illuminate. I recently had work completed on the car, so I'm concerned that a mechanic may have left a component unconnected or improperly installed. Could this be causing both the P0462 (Evaporative Emission System Leak) and U1001 (Vehicle Communication Issue) codes? Any insights or troubleshooting steps would be greatly appreciated.
The issue is specifically with the 2003 Nissan Sentra GXE model, which may have known compatibility issues with emission and communication systems.
