101410 - P16E6

Fault text
Throttle valve, adaptation: Marginal conditions not met;
battery voltage too low

Fault description
The diagnostic function monitors the throttle valve to
determine whether it reaches the lower mechanical travel
stop (UMA) during the initial adaptation.

Condition for fault identification
Test condition:
The fault is recognized when the limits for the approved
signal voltages (signal voltage sensor 1 < 0.27 V, sensor 2 >
4.73 V) are violated during the initial adaptation, or when
the deviation of the sum voltage of sensor 1 and sensor 2 of
5 V exceeds X V.
Potential problem source(s):
- Fault during initial initialization attempt; lower mechanical
travel stop range violation:
- Dirt/contamination on travel stop
- Foreign matter/object(s)
- Sporadic contact resistance
- Defective throttle valve
Terminal condition: Terminal 15
Voltage condition:
- Onboard electrical system voltage between 9 V and 16 V
Temperature condition:
- Engine warmed to normal temp, above 80 °C
Time condition:
- 30 sec. after Terminal 15 on
Other conditions:
- Engine on
- Vehicle velocity = 0 km/h

Condition for fault memory entry
This fault is logged in the control module's fault memory
immediately.

Action in service
- Clear ECU fault memory ? Ignition off? Ignition on for at
least 1 minute
- If fault is still present:
- a. Check wiring harness DME - throttle valve (sum of
throttle valve voltages must equal 5 V)
- b. Inspect to determine whether any objects are present in
the intake manifold or within the throttle valve's travel range
- c. Completely close the throttle valve by hand and
measures the voltages on the two sensors (S1: 0.5 V +/-
tolerance, S2: 4.5 V +/- tolerance)
- Replace throttle valve

Fault effect and breakdown warning
Breakdown notice:
Ability to continue driving is restricted because engine
speed is limited to roughly 1300 rpm.
Possible apparent symptoms:
- Reduced power
