DTC 112: Fault In ECM

If ECM detects a fault in ROM/EPROM or RAM memory circuits, circuit for ECM temperature sensor, knock control circuit, or ECT sensor circuit NTC coupling, DTC 112 is set. If fault is permanent and signal is faulty, replace ECM. If fault is intermittent, erase DTC. If DTC reoccurs, check ECM connector for good terminal contact. If terminal contact is okay, replace ECM.
