Skoda OCTAVIA MK1 Service Manual page 201

Perform resistance measurement
– between the contacts of the valve with
multimeter.
Specified value: approx. 14.5 Ω.
If the engine is warm the resistance
increases by approximately 4 to 6 Ω.
If the nominal value is not reached,
–
replace the injection valve.
B - Checking voltage supply
Test conditions
l Fuel pump relay o.k., test
Fuse for injection valves O.K.
l
flow diagrams and Fitting locations
Disconnect plug at the injection valve to
–
be tested.
Connect the voltage tester between
– contact 1 of the plug and the engine
mass.
Note
So that the engine does not start,
disconnect the plug at the ignition module.
Operate starter for some seconds, the
–
voltage tester must light up.
If the voltage tester does not light up,
check the continuity of the wiring from
– contact 1 to fuse for injection valves and
if necessary eliminate open circuit
→ Current flow diagrams and Fitting
locations.
If the voltage tester lights up, test
–
actuation of the injection valves.
C - Test actuation of the injector valves
Disconnect plug at the injection valve to
–
be tested.
