Trouble code P1627 means: PCM A/D Conversion Malfunction

This is a fuel sending unit code and it directly related to you goofy gas gauge. This is a common problem in 2nd Gen Isuzus. The fuel sending unit needs to be replaced. Most places will tell you that you must replace the entire fuel pump assembly module but you can buy just the sending unit.

Other faults to refer this problem and other codes: P0141, P0300, P0404, P1404, P1627, with this synthoms:
hesitates sometimes on takeoff, gas gauge gives random readings(sometimes will read empty, or full, or somewhere in between), Fuel light flashes sometimes.

Hope helps.
