[darius89]

Hi, have problem with opel Vivaro 2006 2.0 dci
When reach speed around 70km engine cutsoff. And apears p2146 error Roup 1 injectors supply.
restartimg car and runs ok until 70km/hand again.
measured injector wiring ,all ok.
Injector resistance . discomected from ecu

1 --1,6 mOhm
2 -- 4,2 mOhm
3 -- 4,3 mOhm
4 -- 4,1 mOhm

Injector to mase

1 pin1 --1,92 Mohm
pin2 --2.0 mohm

2 pin1 --1,9 mohm
pin2 --2.0 mohm

3 pin1 --5.3 mohm
pin2 --5.1 mohm

4 pin1 --57 mohm
pin2 --54 mohm

I dont know how much should be

[rafal]

change injectors plugs................... it is normal in that car/engine
1st is from left side of car............not like before from gearbox side !!!

[miroopel]

The resistance of the injector is 160-200 kΩ. If it is different, replace the injector.

[darius89]

But my all injector much more than 200 kΩ ...
Not possible that all bad. All 4 injectors was replaced 2 month ago.

[miroopel]

Check the injectors first. Direct check. Sorry for my bad english

[IanBMW]

injectors corroded, from water dripping from plastic lining under front windscreen, on rare occasions ,fault could be ECU water damaged or broken wires in harness
