Multec-M (14 SE / C 14 SE / C 16 SE) F0:DATA LIST
| No. | TECH 1 Display | Conditions for Checking | Nominal Value | Trouble Codes | Terminal |
|---|---|---|---|---|---|
| 14 | ENGINE SPEED | Engine running at idle speed, |
operating temperature
Astra-F
Corsa-A, Corsa-B, Nova
820 to 980 rpm
| 850 to 1010 rpm | 19,35 | A 2 / B 3 |
"ENGINE SPEED" is dependent on various input signals and the control unit programming.
If the actual value is not within the nominal value, first check the other sensor signals.
| Trouble-shooting: | Nominal Value: | Cause of Fault: |

| (If nominal value is not attained) |
· Check inductive pulse pick-up P 35:
· Ignition OFF
· Disconnect control unit plug
· Using multimeter, measure resistance:
from: inductive pulse pick-up P 35 Ter. 1
to: control unit plug Ter. A 2
| less than 2 W | · Lead interruption |
from: inductive pulse pick-up P 35 Ter. 1
to: control unit plug Ter. A 2
· Using multimeter, measure voltage:

| less than 2 W | · Lead interruption in shielding |
· Further causes of fault:
| · Defective inductive pulse pick-up |
· Burr on toothed disc
· Gap from inductive pulse pick-up P 35 to toothed disc incorrect. See Service Instructions.
· Select TECH 1 mode "F8" with arrow keys, increase and decrease idle speed:
Engine speed increases
| and decreases | · Carry out test step 06 |
· Loose contact in throttle valve potentiometer
