Bradford Posted November 8, 2018 Share Posted November 8, 2018 I've got a 98 ch 612 with e7 etech and it keeps intermittently ringing the buzzer with the shut down light. I replaced the fan clutch solenoid and it went away for a few hours. Now the light and buzzer still come on. I slammed my tailgate today and it shut off. Still flashing a 4-2 code. I checked the wires on the coolant sensor and they seem okay along with the ac high side pressure sensor. Do I need to replace both sensors?

Bradford Posted November 8, 2018 Author Share Posted November 8, 2018 Now I just got it started back up and when I shut my hood it shut back off. Is my wiring harness shot, and letting wires rub during the right vibrations? Quote Link to comment Share on other sites More sharing options...
hatcity Posted November 9, 2018 Share Posted November 9, 2018 4-2 is "fan clutch output" according to my sheet.
