How to Check the Efficiency of the Glow Plug

Model: Peugeot 308 T7, MK 1 - Years 2007-2014
Part: Glow plugs

The glow plug is an electric resistance that, when powered, heats up due to the Joule effect, raising the temperature of the combustion chamber to an optimal value for fuel ignition during the starting phase. Once the glow plug is removed, you can check its efficiency using a multimeter: the first thing to check is that the resistance is not broken. Set the multimeter to the continuity function, where the tester beeps when the probes are connected, and place the probes at both ends of the glow plug. If the multimeter does not beep, then the resistance is open.
