Code 1-1-2: Fault In ECM

  1. 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.
  2. Clear code. If code reoccurs, replace ECM. If code does not reoccur, fault was intermittent.
