Code 1-1-2: Fault In ECM
- If ECM detects a fault in ROM/EPROM or RAM memory circuits, circuit for ECM's temperature sensor, knock control circuit, or ECT sensor circuit's NTC coupling, code 1-1-2 is set. If codes 4-3-2 and 5-1-3 are also present, go to testing for those codes. If these codes are not present, go to next step.
- Clear code. If code reoccurs, replace ECM. If code does not reoccur, fault was intermittent.
