Fault symptoms
On-Board Diagnostics
Type of diagnosis:
-
|
Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.
|
Enable criteria:
-
|
Engine running. Main relay voltage exceeding 11V. Coolant temperature exceeding 60 °C.
|
Fault criteria:
-
|
Knock voltage below 0.25 V on sparking for 25 ignitions.
|
Dependents:
-
|
P0116, P0117 and P0118.
|
System reaction to a fault:
-
|
Knock signal set to 5V. In this way knock detection will take place continuously on all cylinders when under high load.
|
OK report:
-
|
Enable criteria fulfilled. Fault criteria not fulfilled within 120 s.
|
Fault handling:
(See section
Fault handling III, other emission-related components and functions

Diagnostic help
Fault diagnosis concerns electrical faults in connecting cables or in the ignition discharge module.
Diagnostic tool functions related to this fault are:
•
|
Knock sensor reading, in V.
|
See also description of read values in
Menu "Read Values"
for more information.
Note
|
The knock sensor is an internal ignition discharge module function. There is no external sensor.
