having issues with my 07 crd. code reader read p0670 glow plug module.
cicuit malfunction. will get part and replace myself as it looks fairly
easy. really appreciate the upload man. life saver
Thanks for this. I’d ordered a module for a mechanic to fit, but when I saw
how easy it was to get at on your video I decided to do it myself. So
simple and quick.
ok… that’s what Im thinking also… I found the module for $162 New…
Would you recommend I change some glow plugs first or should I go straight
to buying the Module?
Im leaning more towards buying the module…
On a side note… have you had trouble with the EGR Valve? Im getting a
code reading there is problems and Im tryin to pull off the Valve but its
really stock on there… Im trying not to get too frustrated and grab the
Sludge hammer… But Im getting close…
How do you know if your Mudule is bad or if its the Glow Plugs? Last week
my Glow Plug * showed an error then it cleared on its own… now today it
says glow plug 2 error…
Quick question please, in the morning it take for ever to start. I thought
it was service the car needed, i did it change everything fuel filter oil
filter it all. I even replaced the battery thinking that was the issues as
well. But now I seriously think its the glow plug. Because it only hapeens
in the morning when the car sets for while. I have zero warning signs or
codes on my dash. Please help i am in the carribean , no one knows this
car. 2009 jeep cherokee 3.0 crd
No, if you’re in the Caribbean it is likely not the glow plugs that are a
problem. That engine will start in warm weather with no glow plugs at all.
Other’s may chime in here but perhaps a fuel system problem is the culprit.
This vehicle is also known for EGR valve problems as well. Are you getting
any hesitation, skipping, bucking, or rough shut downs?
I’ve also read that the module causes glow plug failures by giving them too
much voltage for too long at times. I read of one case where this was
ignored and the ceramic glow plug end broke off and fell into the cylinder
causing major damage.
I have a 2007 3.0 and am in los angeles my car was just diagnosed as
needing 4 glow plugs swirl valves manifolds and actuators ANY IDEAS HELP
WOULD BE MUCH APPRECIATED
It sounds more like a battery fault which in turn will cause other issues.
A good battery will easily crank a Cherokee for more than 8 seconds before
slowing. Batteries only last 3 to 4 years. Times up buy a new battery. I
live in the southern sub tropics and you don’t need glow plugs in temps
above 25c
It would be odd to have 4 glow plugs fail at once. I’d get a second opinion
from another shop first. Make absolutely sure that the swirl valve motor
and manifolds need replacing before spending the money because it is very
costly to do so. If you find somebody with expertise, you can lock the
swirl valves in an open position and install a fuse in the wiring to fool
the computer in thinking the swirl motor is fine. It is for ideal
combustion and emissions.
If no different then the cap is not the problem. Another person suggested
both ‘camshaft position sensor’ as well as’ fuel pressure control solenoid’
The glow plugs are really only needed for cold starting. I can’t imagine it
really gets all that cold in the morning where you are. My wife forgot
about the glow plug thing several time when we first got it in the fall in
Canada and just turned the motor over without waiting and it starts within
2 seconds in less than 10 degree Celsius weather
Okay, it may indeed be the glow plugs but I still have my doubts. An easy
thing to try first one person mentioned is to take your gas cap off before
you try and start it and see if air wants to draw into the tank. This
indicates a non-venting cap which causes the fuel delivery to have
problems. Put the cap back on and then crank it and see if it starts
faster.
thank you very much for your response, just today there is an article on
fox news about auto shops ripping customers off I am in the los angeles
area do you perhaps know of an honest mechanic in the area and where is the
best place to buy the module?
I have a 2008 3.0. I have done one glow plug already (#3) and now the # 6
is due…should i just do all at once…. I have been hearing that this
module you changed is what can be causing the GP failures….. ps I am from
Cornwall Ontario and have a 2008 limited S 154k Jack
The MIL would come on at every start up and my code reader was actually
saying “Glow plug number 2” was faulty. After changing 3 glow plugs (to be
sure I got the correct # 2 plug) it was still happening. I replaced the
module and the light went out on the next start up and has been fine since.

To my knowledge there is no set replacement time for glow plugs. How long
they last can depend largely on how many start up cycles have occured.
Also, I’ve been warned to always wait before the glow plug light turns off
before cranking; I guess this can be bad for them as well. My code reader
said the # 2 plug was bad but actually it was fine, it was the module
throwing the code all along. Opinions may differ on this but I’ve been told
by the Diesel tech to just replace as they wear out.

I would say module since that was the exact same behavior I had…and
that’s a great price for it by the way!

It drains my battery

How long is it taking to start?
I connected and obd2 scanner on it and it says glow plugs…But it didnt
say which cylinder…So i just ordered all six.

abou 8-15 seconds, which it drains the battery..
thank you yess you saved me money.. mechanics were going to charge me 1.5
hours labor~~~~ xoixoxoxoxoxoxox

Just changed mine on the same jeep. This helped a lot. Thanks man!
