Tim Modine Posted June 3, 2021 Share Posted June 3, 2021 Getting the 3-2 lightning bolt flashing code as well as a 5-8.Im concerned with both but the 3-2 sounds worrisome. Anyone have the 3-2 code and experience with it.Hoping its a sensor. Intermittently my intake manifold pressure gauge will read low around 5 psi then after a 1/2mile or so gets up to 30 psi ish. happens occasionally couple times a day. Any help or info would be appreciated. Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/66892-2017-chn613-aset-460-code/ Share on other sites More sharing options...
Joey Mack Posted June 3, 2021 Share Posted June 3, 2021 (edited) The year and model dont jive, however that code is "Engine RPM" The sensor in the flywheel housing, right where the clutch cable is mounted... Un plug the Cam sensor, and try to start the engine. if it doesnt start, the fly wheel sensor, or wires, etc. is bad.. jojo Edited June 3, 2021 by Joey Mack More content needed Quote Link to comment https://www.bigmacktrucks.com/topic/66892-2017-chn613-aset-460-code/#findComment-474670 Share on other sites More sharing options...
