Step 5 If this voltage checks out, refer to the manual to identify the alternator field duty cycle circuit. You need to have the charging system checked. A few days ago on the way to work, my 2005 limited flashed a P2096 Downdraft O2 sensor and a P0533 O2low voltage. No, it's not Even going to be fun to remove, and check this harness! May 21, 2015 Hey Joe , The first thing to do would be check for battery voltage on the heavier gage wire on the back of the alternator , if there is no voltage here there is a open circuit! I am getting P0622 on my Chrysler Town and Country. Since there were about ten wires of various sizes involved at this ground point I decided to separate them into two groups and used 10 gauge terminals and wires to bring it all together. You will also notice an absence of images related to the actual wiring repair. So assuming and we all know what that means i took the battery out and took it to Autozone to test.
The ignition switch controls turning on the charging system. You could damage all the electrical system if not careful. The G103 ground point re established. I used heat shrink tubing to insulate the terminals. Check that when the ignition is on, that you are getting 12 volts to the lead to the alternator.
If the battery is not putting out 12 volts it will make things crazy. When I opened the tabs that secured the wire insulation the terminal fell off because the wire had completely corroded loose. The image below shows the typical connections that commonly appear on most alternators today. There was no ground present on the black wire. You should also check that the spark plug gap is set properly. Every three to four months I would peel the silicone off of a section of bare wire and inspect for damage. That is what I would do, anyway.
These wiring harnesses have a bad rep for intermittent breaks, in the wires of the harness. If you do this make sure that your sealer is not corrosive to copper. You should see more than 13. They are much more knowledgeable and professional. Good luck, jim May 01, 2011 Make sure the battery connections are clean and tight. How do I test the generator field? However, on the 40 mile trek from work, the battery light came on.
The easiest way to find out what this light is telling you is to hook your vehicle up to a scan tool. This time the codes are,P0622 generator f terminal circuit p2503 charging system low voltage , P0133 o2 sensor slow response. On the 3rd day, the battery light came on and tested at 11 volts again. I still get the 'Giggles' when I think about it!! There was power on the green wire with the ignition on and the engine off. Do you have the charge indicator lit on the dash? You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage.
I recently got a battery light on my dash. Be aware though that faults of this nature can be extremely challenging and time consuming even for professional technicians to find and repair. However, as soon as the engine starts and the alternator is generating a current, the duty cycle should read from about 5%, to 100%, depending on the required current. Apr 18, 2014 My guess is you may have wired something up wrong, or installed a faulty part. If you have a scan tool you can actuate the field driver circuit and check for a flashing light at the installed test lamp. How do you troubleshoot code P0622? This is one of those car maintenance problems, which are easy to handle, given the variety and quality of products available in the market today. You should see at least 13.
A wire brush and persistence will work though. It should be illuminated to some degree. I also need to remind you and myself to always consult a wiring diagram to see how a system operates. I normally do not even bother checking for ohms of resistance in a circuit like this because the results can be deceptive. If you do wiring repair I suggest you do the same test with whatever sealer you choose to use.
I made sure he ground and other connection were on surely and now the battery light has returned. But they cost alittle more. Spark plugs typically need to be replaced every season or 25 hours of use. In this case there was no light so further testing would be needed. This 2006 Chrysler Sebring came in with several electrical problems but the chief concern was that the alternator was not charging. The customer also stated that the wipers did not work and that the check engine light has been on for a while. You can verify this by checking voltage at the battery with the engine running.
Posted on Feb 24, 2010 Normally an alternator should read in the 13 to 14. But it will charge the battery. This required because the code setting parameters of code P0622 vary between manufacturers, and in some cases, P0622 will set as the result of other, unrelated failures. I have a 2002 Chrysler Concorde lx 2. Sometimes you can take it to an Autozone, and they can clear it for you! This cost money and it will turn the battery light off.
