Camshaft Signal (Maximum Angular Variation In 'Retarded' Direction)

Angle Variation of Camshaft to Crankshaft :: Camshaft Signal (Maximum Angular Variation In 'Retarded' Direction (P0370)

Check Angular Variation of Camshaft to Crankshaft.





Figure legend
- 1 Signal from component L5 (Crankshaft position sensor)
- 2 Signal from component B6/1 (Camshaft Hall sensor)
- 3 Signal from component B6/1 (Camshaft Hall sensor): maximum angular variation in 'retarded' direction
- 4 Signal from component B6/1 (Camshaft Hall sensor): maximum angular variation in 'advanced' direction
- Additional information : If an angular variation of more than 15� exists between camshaft and crankshaft, a fault is then stored in the fault memory.

Note
- Measuring system HMS990 integrated in STAR DIAGNOSIS, is required for performing the next test step.Switch on measuring system HMS990 for this step.Continue with key F3
- If measuring system HMS990 is not integrated in your STAR DIAGNOSIS, it is also possible to carry out the next tests with alternative measuring equipment such as oscilloscope, pressure gage or digital multimeter.Continue with key F4

Question
- Is measuring system HMS990 to be started?

Question
- Is the angular variation between crankshaft and camshaft greater than ±15°?
Yes
Possible cause and remedy
- Timing chain wear or timing chain stretch
- Mismatch between timing chain and camshaft sprocket or crankshaft sprocket (timing chain jumped)
No
The test was okay. ** End of Test **
