A: DTC P0011 INTAKE CAMSHAFT POSITION - TIMING OVER-ADVANCED OR
SYSTEM PERFORMANCE (BANK 1)
1. OUTLINE OF DIAGNOSIS
Detect the AVCS system malfunction.
Judge NG when the amount of AVCS actual timing advance does not approach to the amount of AVCS target
timing advance.

Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
5. DIAGNOSTIC METHOD
1) When the conditions during which the differences of AVCS target timing advance amount and AVCS ac-
tual timing advance amount is large continues for certain amount of time.
2) When the differences of target timing advance amount and actual timing advance amount is calculated
during AVCS control, and the difference per predetermined time is the specified value or larger.
• Abnormality Judgement
Judge as NG when the following conditions are established within the predetermined time.
Time Needed for Diagnosis: 30000 ms
Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cy-
cles.
• Normality Judgement
Judge as OK and clear the NG if the following conditions are established within the predetermined time.
Time Needed for Diagnosis: 30000 ms
