Hello, plug #2 is obviously dead and will need replacement. A new healthy plug will have a resistance of 0.5-1.0 oms out of the engine. When the same plug its testbed in the engine like in this video it can show 1-5 oms. Did you test the plugs after getting out to see if the readings were different? 🤔

I'm hopeful I'll get a reply today , might you be interested in replyi g to me , Could you please happen to know , I've got a Honda civic mk8 2007 2.2 diesel , battery was checked last year , it gave 12v at the time , therefore should be just fine , For a while now it has started to "struggle" to start , especially on cold, which I found out it might be from the plugs , will it be worth cleaning them or , just test them see their resistance and maybe change them if needed , car drives just fine ( it mght be me seems a bit weaker than before ) but has a quite rough start Much apreciated ,

Hello. Thank you very much for your video. One question please: I need to change them. But I can buy 4 glow plugs of 0,5 ohm-s or 1 ohm-s. Which one is better??? 1 ohm??? 0,5 ohm??? These are cheaper, almost half price than the 1 ohm-s. Thank you very much. Have a nice day.

All those glow plugs with undrr 5- 6 oms is actually fine. You said they are dead but they are perfectly fine. Only 1 which is dead and needs changing

Would you expect to see 12 v at the leads with ignition on but not running.?

[@junaidahmed8694]

great video

[@Sportage5603]

Mine are reading 40ohms in situ in the engine block but thats all 4 seems odd they all are the same reading? Chugs a bit when temps are cold

How can you test glow plugs if there completley hidden like on the citroen relay. ? 🇬🇧

Please where's the glow plugs control module location in Honda CR-V 2012 diesel

[@ryanh3285]

I'm getting 2.4 volts at the lead with the engine running and no glow plug symbol at all on the dash when turning ignition on.

Would a glow plug light still come on and go off after a few seconds if the relay was bad?

[@ORileysAutos]

Yes
