    I have a customer with code issues. I don't work on Internationals, but I do know HEUI style fuel systems. He has code 124 that I cannot get to erase even with engine off. Code 332 also was logged but I got it to erase. He had injectors put in several months ago and engine has been running fine with no starting issues. He also had ICP sensor replaced. If I am reading correctly, the code 124 is for ICP signal out of range low and 332 is ICP above spec with engine off. Inspected wiring and ICP connector, seems to be in good condition. Does the 124 code log with engine off also? the HPOP is not very old either. He does not drive truck every day so there are not a lot of hours on repairs. I am thinking the sensor could be bad. Any suggestions. Would like to help the customer out.
