Circuit/Component Description
Camshaft adjustment occurs depending on engine load and RPM. Camshaft adjustment valve is opened by
ECM, directing oil pressure to camshaft adjuster, which moves camshaft. Camshaft adjuster may fail either
electrically or mechanically. After verifying or repairing electrical portion of system, camshaft adjuster may still
be faulty. Repair camshaft adjuster mechanical failure as necessary. See step 6 under TESTING PROCEDURE.
Test Requirements
Ensure all fuses are okay, battery voltage is at least 11.5 volts and fuel pump relay is okay. Ensure all electrical
accessories are off and A/C is off. Ensure engine is mechanically sound. Ensure no intake or exhaust system
leaks exist. Ensure engine coolant temperature is at least 176°F (80°C).
Testing Procedure
1.
NOTE:
Before replacing any component, verify battery voltage is a minimum of 11.5
volts and all fuses are okay. Ensure all wiring is okay and connectors at
component and ECM are clean and tight. When codes have been cleared or
voltage supply to ECM has been interrupted, ECM loses all "learned" and
"basic" values. Serious driveability problems may occur depending on vehicle
mileage. After reconnecting ECM, it is necessary to perform relearn procedure.
See TEST DRIVE RELEARN PROCEDURE .
NOTE:
If a test ends with ECM replacement. Before replacing ECM be certain that, all
wiring, power and ground supplies are okay. See ENGINE PERFORMANCE in
SYSTEM WIRING DIAGRAMS article in ELECTRICAL and ECM GROUND &
VOLTAGE SUPPLY .
NOTE:
Output Diagnostic Test Mode is used when using Scan Tools VAG 1551/1552 or
VAS 5051/5052, always continue with output diagnostic test mode until last
component in output diagnostic test mode test sequence has been checked. If
you are not using Scan Tools VAG 1551/1552 or VAS 5051/5052 follow scan tool
manufacturer's instructions.
NOTE:
When using scan tool to activate camshaft adjustment valve, it is barely
