Ignition and Control Systems - Specifications, Other (Xc): Maintenance Volvo V70 II

Camshaft reset valve

Measurement range 0-100 %

The pulse ratio transmitted by the engine control module (ECM) to control the camshaft reset valve.

The value indicates control of the camshaft reset valve to control the camshaft shift angle.

The value decreases with increased control of the camshaft shift angle. When the camshaft shift angle reaches the control module target value the pulse ratio is 50% (10 %).

Reset valve camshaft, (intake / exhaust)

Exhaust camshaft reset valve: turbocharged engines

Measurement range 0-100 %

The pulse ratio transmitted by the engine control module (ECM) to control the camshaft reset valve.

The value indicates control of the camshaft reset valve to control the camshaft shift angle.

The value decreases with increased control of the camshaft shift angle.

Reset valve camshaft, intake/exhaust

Measurement range 0 - 100 %

The pulse ratio transmitted by the engine control module (ECM) to control the camshaft reset valve.

The value indicates control of the camshaft reset valve to control the camshaft shift angle.

The normal value varies depending on how much the camshaft is controlled.

Measurement range 0-100 %

The pulse ratio transmitted by the control module to control the camshaft reset valve.

The value indicates control of the camshaft reset valve to control the camshaft shift angle.

The normal value varies depending on how much the camshaft is controlled.

Reset valve camshaft, intake / exhaust (CA)

Measurement range: 0-100%

The pulse ratio transmitted by the engine control module (ECM) to control the camshaft reset valve.

The value indicates control of the camshaft reset valve to control the camshaft position (angle).

The normal value when the camshaft is deployed and in the fixed position is approximately 50%. The value increases/decreases depending on control of the camshaft.
