DTC DETECTING CONDITION: Detected when two consecutive driving cycles with fault occur. TROUBLE SYMPTOM: • Hard to start • Improper idling • Poor driving performance CAUTION: After servicing or replacing faulty parts, perform Clear Memory Mode Clear Memory Mode > OPERATION, and Inspection Mode Inspection Mode > PROCEDURE.
1. OUTLINE OF DIAGNOSIS Detect the malfunction of the engine oil temperature sensor output properties. Using the following two diagnoses, judge as NG when either is NG. • Diagnosis 1 (correlation diagnosis): After the engine starts after the specified period of soaking time has elapsed, diagnose by correlation between engine oil temperature sensor value, engine coolant temperature sensor value and intake air temperature sensor value. Judge as NG when the differences are both above the specified value by comparing between engine oil temperature and engine coolant temperature, engine oil temperature and intake air temperature. • Diagnosis 2 (function diagnosis): Judge as NG when engine oil temperature does not rise to the specified value regardless of an engine running condition that clears certain conditions. 2. COMPONENT DESCRIPTION
3. EXECUTION CONDITION
4. GENERAL DRIVING CYCLE • Diagnosis 1: Perform the diagnosis only once after the engine starts after a certain period of soaking time. • Diagnosis 2: Perform the diagnosis only once after starting the engine from cold condition. 5. DIAGNOSTIC METHOD Judge as NG when Diagnosis 1 or Diagnosis 2 becomes NG. If the duration of time while the following conditions are met is longer than the time indicated, judge as NG. Diagnosis 1
Time Needed for Diagnosis: Less than 1 second Diagnosis 2
Time Needed for Diagnosis: Value of Map 2 Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cycles. |
