Fault symptom

Fault indicator lamp (for further information see WIS Fault diagnosis, general)

Cruise control not working.

Limp home

On-board diagnosis

Type of diagnosis:

Continuous

Enable criteria:

When the ECM is awake, diagnosis is active (even with the ignition off).
NONE of the following DTCs must be detected:
P0122, P0123, P0222, P0223

Fault criteria:

When the difference in voltage between throttle position sensors 1 and 2 is 4 - 8%, depending on the position of the throttle (4% for unactuated pedal, 8% for fully depressed pedal).

Dependent:

None

System reaction to a fault:

Correction of mass air flow/combustion for fuel calculation is blocked.
Limited acceleration and idle function.
Cruise control blocked.
Secondary air switched off.

OK report:

Fault criterion not fulfilled and vehicle speed over 0 km/h for more than 60 s.

Fault handling:

Type III
(See section Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness

Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.

Diagnostic help

Diagnosis regards:

Electrical fault in connecting leads or component.
