GENERAL DESCRIPTION
DR:DTC P2089 INTAKE CAMSHAFT POSITION ACTUATOR CONTROL CIRCUIT
HIGH (BANK 1)
1. OUTLINE OF DIAGNOSIS
Detect open or short circuit of oil flow control solenoid valve.
Judge as NG when the current is large even though the duty signal is small.
2. ENABLE CONDITIONS
Secondary Parameters
None
3. GENERAL DRIVING CYCLE
Always perform the diagnosis continuously.
4. DIAGNOSTIC METHOD
• Abnormality Judgement
If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.
Judgement Value
Malfunction Criteria
