  • Need help with an engine code for an Isuzu 5.2 L. P160B after I replaced the glow plug control module

  • Is there a way to reset this code? I have a scan tool but it returns immediately. Parts dealer stated it is a part that does not need to be programmed.

  • If the code returns, that means that there is still a problem. What model and year is your Isuzu? and what code number did you get?

  • Had to break down and take it into the shop.. The issue was after changing to injectors I did not have the software to reprogram them... Greennhorn mistake...lol

  • The injectors have a QR code tag on them and must be reprogrammed into the ecu.

  • Mark, you need to have the dealer rewrite the injectors, so that the calibration numbers would register in the GPCM.
