P067200 code

Hi all
Sorry to ask but the following code keeps coming up on my code reader and want to know is it correct what it is saying.
P067200-Passive/Sporaaic Cylinder 2 Glow Plug Circuit
Is this a true code for no2 glow plug not working and just wants a new glow plug putting in ?
Just don’t want to change a glow plug if it’s not that.
Thank you

You need a multimeter to test the resistance of the existing glow plug, and test for voltage on the cable end. Then you'll know whether to replace the plug, or trace a wiring fault.

Do you know what the reading should be ?

The glow plugs will be under 1 Ohm, check them all for reference.
They will be 12 Volts, or possibly 7 Volts, again check all cable ends for reference. Cycle the ignition on a cold engine to power them up.
