Automotive Connector Repair and Test (2007-2011 Toyota Camry Ignition Coil Pigtails)

Here's a quick way to test, diagnose and re-pin your automotive connectors. I couldn't find a good enough tutorial so I made one for you. This should assist with all makes and models, and all types of connectors. Use the basic knowledge I provide you here to fix and solve your own problems.
Let me know if this was helpful! Thanks for watching!

Thanks sir

Yes sir, hope it was helpful!

[@danielbowersmusic]

Thank you for the video! If anybody has any ideas I have a MK4 Jetta with a cylinder #3 misfire. It's not the coil, spark plug, injector and coil connector tests good on multimeter. It's also not a compression issue. What do you guys think it could be? The ECU? Grounding issue?

[@Bronze_T_Garage]

Pull the plug to see if you are running lean or running rich.

[@encinobalboa]

Some years and models of Toyota and Lexus have crappy connectors. Other years are good and last forever. Depends on who was supplying at the time.

[@train5640]

Can a bad wire cause a ignition coil to keep going bad? My mom keeps having to replace them every couple of months.

[@Bronze_T_Garage]

Yes, but also a bad spark plug can cause it. What vehicle is it on? And do you see oil in the hole when you swap it out?

[@user-wz1zu5bg1t]

great info thank you, i have vw mk5 R32 having this P0351 code its intermittent misfire with rough idle, changed new coil original vw and all spark plugs changed and connectors. i can see a strong spark out of the coil for cylinder 1. how likely this issue is caused by a faulty ECU and if its the ecu would the coil still fire normally and constantly maybe signal sent wrong from ecu? would appreciate your feedback

[@Bronze_T_Garage]

First, I would like you to switch cylinder 1 coil with another. It is possible that the new coil is having issues or is damaged. Let me know if that changes anything. Second, did you see any oil in or on the tube or spark plug when you pulled the coil? Third, are you getting any other codes?

[@user-wz1zu5bg1t]

@@Bronze_T_Garage i switched the coil to diff cylinder and still cylinder one misfire, no oil on spark plugs. the change i found since started having this issue is the car on cold start revs on lower rpm 700 all the time don' t know if it is related in any way, pcv valve is new, compression test showed normal readings still i need to try it while is engine is cold. i am confused about this

[@user-wz1zu5bg1t]

@@Bronze_T_Garage other codes are P0300 and P0301

[@user-wz1zu5bg1t]

did the test as you instructed in the video and readings came out the same on all coil connectors

[@user-wz1zu5bg1t]

the readings were: around 12 V on 3 pins and on one pin 0.2 thats for all coil connectors

[@crimmie114]

What if when i put the key in the ignition before it cranks, theres nothing for the ground in the wires?

[@Bronze_T_Garage]

You should have a constant ground unless you have an antique vehicle. Make sure you pay attention to the voltmeter and ensure your probes are installed correctly. It could be that you are reading it backwards... it could also be that something is wired backwards.

[@juliustay2541]

In checking the voltage of the connector, can i interchange the positive and negative probes? That is using the red probe to check the voltage in the connector whiles black probe is connected to the negative battery terminal?

[@Bronze_T_Garage]

You sure can. It will just read the opposite. For instance, +12 volts will read -12 volts.

[@juliustay2541]

@@Bronze_T_Garage Oh OK. Thank you.

[@juliustay2541]

Do you have a video on how to check voltage or resistance in the transmission wire connector for Toyota?

[@Bronze_T_Garage]

I do not, but I can make one soon enough. All you really need to do is look up a schematic and it should tell you. If not, then you can locate the power and ground pretty easy, the same way I show with these connectors.@@juliustay2541

[@JoseSandoval-ic5xe]

Hi I'm having a misfire on cylinder 3 my connectors have only 2 wires, after watching this video with accessories on I get 12 volts on both sides in this connector and other 3 cylinders are 12 volts one side and 5 other. Does this mean Cylinder 3 is shorting out? Also when I wiggle down further it fixes itself.

[@Bronze_T_Garage]

Sounds like you have a break in that 5v wire and the 12v wire at the same spot or at the connector.

[@JoseSandoval-ic5xe]

@@Bronze_T_Garage Hi thanks for your response would a car electrician be able to rewire to fix this issue? Sorry by break do you mean short?

[@Bronze_T_Garage]

@JoseSandoval-ic5xe yes, a short is simply when two wires are touching. I say a break in the wire to identify that likely the plastic lining over the wire has broken. You can take it to just about any mechanic for a fix. Just let them know your findings.

[@priinceanthonykoldd7071]

Ik this question is not related but I have a 1998 Lincoln town car & it just won’t start. I had 3 bad fuel injectors and coils so I did all 8 of both and even bought a new alternator & no start. What is the most common case in this situation? No compression, no spark, bad ground or bad starter ?

[@Bronze_T_Garage]

Buddy, from the sound of it you've had someone in your ear giving you bad info. First thing to check is to make sure you have spark, then you need to make sure you have fuel, and then if you're not getting air... well that's just unusual. Lol

[@priinceanthonykoldd7071]

@@Bronze_T_Garage no I have just checked them myself and at first the car didn’t have that problem it was misfiring when I would get up to 40mph so that’s how I found that out and fixed what I fixed than stop starting after I put gas in the car. Is a spark plug tester good ? In for fuel a fuel pressure gauge is good ? Idk how to test for air in the system lol

[@Bronze_T_Garage]

@priinceanthonykoldd7071 start by testing for spark, and also ensure that your plug wires are in the right spots, and that your spark plugs are tightened down. Examine your spark plugs and check to see their condition. Google, "how to diagnose a spark plug."

[@mike75479]

I was doing a repair on the car cranking it then suddenly the power to ignition coils stopped, only the starter will turn and ignition coils will not fire anymore Do you know where the relay is for ignition coils? Only the starter and crankshaft are turning

[@Bronze_T_Garage]

Should be in the box located near the shock tower under the hood.

[@Bronze_T_Garage]

Look for the "ignition relay"

[@mike75479]

Still not fixed, turn the switch on tested all plugs and it gives same reading as you did. When ignition is on, there is one fuse called A/F it’s 20 there is no power to it. And crankshaft position sensor, I test it is working. Not really sure what’s the issue. I did point crankshaft pulley pin point to the 0 line twice still not firing, only starter turns. Do I need to keep pointing the pulley to 0 mark and try

[@user-ho6kt3rq2e]

Bonjour ! Pouvez vous m'indiquer sur ma question pour mon Toyota camry 2010 éssance ?

[@Bronze_T_Garage]

Sure, what is your question?

[@David-qw2iv]

While checking connectors is the key in ignition at all

[@Bronze_T_Garage]

Yes, put the car in on mode without cranking it. Should be able to use the windshield wipers if the key is on mode, it is the second click.

[@Bronze_T_Garage]

@@David-qw2iv what's your battery voltage?

[@Bronze_T_Garage]

@@David-qw2iv I want you to see if you have ground at the starter bolt and ground at the end of the ground wire. Ensure that it is a strong ground by checking the voltage through it.

[@greed6is6good]

Can the average Joe do this without burning the car computer?

[@Bronze_T_Garage]

Yes, very much so.

[@augustinasnavickas5268]

can this cause misfire?

[@Bronze_T_Garage]

Yes, very much so! I encourage you to check your spark plugs first. Type into google "What does a healthy spark plug look like?" If it isn't a healthy spark plug, start there. If your spark plug is good, I recommend swapping the coil that is on the misfiring cylinder with another cylinder that is not misfiring. This will tell you if it is the coil. If it is not the coil, then you need to check the wiring on the plugs and do what I did in this video.
