Does any one know if a faulty Alternator would cause a fault code 42. This is an intermittent problem that happens every now and again after taking my 3.8 v6 powered hilux through a river a while back. I have checked both wires from ecu to dfi,checked the ecu itself,checked the earth's to ecu,power to ecu ,replaced the coil packs with MSD as one has failed recently..(not to fix the 42 code problem).it has new leads..CAS is working fine,the battery is good, harness is in good condition,have checked terminals on plugs ends,and I'm completely baffled. When I use my indicator I've noticed the volt gauge fluctuating more than usual..thinking maybey this is the fault,and the voltage regulator in the Alternator is causing it?
