On-Board Diagnostics
Type of diagnosis:
|
-
|
Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.
|
Enable criteria:
|
-
|
General conditions for this trouble code: Atmospheric pressure must exceed 72 kPa and the engine coolant and intake air temperature must exceed -7°C.
|
|
-
|
Crankshaft rotating. Temperature is read every second. For 5 consecutive readings, the value does not deviate more than 5°C from the previous reading.
|
Fault criteria:
|
-
|
The mean value of the difference between the 5 readings exceeds 10°C.
|
Dependents:
System reaction to a fault
:
|
-
|
A substitute value is calculated continuously as follows: Starting intake air temperature is incremented with 1°C per 60 g air mass/s. The value is maximized to 90°C and is used as soon as fault criteria for the sensor are fulfilled.
|
OK report:
|
-
|
Enable criteria fulfilled without any faults being reported.
|
Fault handling:

Fault handling III, other emission-related components and functions

Diagnostic help
Fault diagnosis concerns an electrical fault in connecting leads or in the sensor.
Functions in the diagnostic tool related to the fault:
|
•
|
Diagnostic status for the diagnosis.
|
|
•
|
Temperature sensor reading, in °C.

Menu "Read Values"
for more information.
Checking the wiring
Jiggle the wiring harness at several points and in different directions to detect intermittent breaks and short circuits. Observe the multimeter, diagnostic tool or test lamp during the check.
