107202 - P169A
Fault text
Throttle valve, start check: check, emergency-air position
Fault description
The diagnostic function determines whether the throttle
valve reaches the emergency-air position during the start
test.
Condition for fault identification
Test condition:
The fault is recognized when the throttle valve fails to reach
the emergency-air position in the specified time when
current supply is deactivated while it is in the 17� position
during the activation test.
Potential problem source(s):
- Throttle valve operation impaired by contamination
- Defective wiring harness between DME and throttle valve
- Defective throttle valve
Terminal condition: Terminal 15
Voltage condition:
- Electrical system voltage > 10 V
Temperature condition:
- Intake air temperature > -10 °C
- Coolant temperature > -10 °C
- Coolant temperature < 142 °C
Time condition:
- 5 sec.
Other conditions:
- Terminal status switch without convenience start
Condition for fault memory entry
This fault is logged in the control module's fault memory if
it remains present for longer than 1 sec.
Action in service
- When not under current the two sensors must provide the
following voltage values: S1: 0.86 V (+/- 0.3 V), S2: 4.14 V
(+/- 0.3 V)
- Check wires to throttle-valve sensors
- Check valve for stiction and contamination
- Visual examination of plug contacts (at components,
wiring harness and DME),
- Component malfunction unlikely, only replace throttle
valve in response to emergency
Fault effect and breakdown warning
Breakdown notice:
- The engine reverts to the limp-home mode, continued
driving possible but subject to severe restrictions, stop and
wait for service assistance as soon as possible.
Possible apparent symptoms:
- Power reduction
- Engine speed governed
Driver information
Warning light:
- ECE emissions warning lamp: on
- US emissions warning lamp: on
- ECE electronic engine power reduction: on
- US electronic engine power reduction: on
- CC message: on
Service instruction
- To repair the fault determine whether the requested initial
adaptation has recognized faults and repair these using the
test plan.
