I called the guy that owns the van and the guy that worked on it before me changed the fuse box. Do study this wiring image before performing any wiring work, especially when working alone. If that voltage is missing during cranking, suspect those two sensors. On 85 30 and 86 thay have nothing. Be aware too that if you remove the crank sensor, it requires a paper spacer to be stuck to the end of it when reinstalling it to set the air gap. I was going to post a corrected diagram,.
Code 123 is for the throttle position sensor signal voltage too high. Click on image to view it larger in a new tab. There was a mistake in one of my service manuals a few months ago and they showed 85 and 86 switched around. It is important to first understand about car wiring system first, especially the starting system, before performing any wiring work on your own. Now, here's where it gets interesting, and confusing. Click on image to view it larger in a new tab. This vehicle uses a 1-wire door locking system requiring a - negative through a 5200 ohm resistor for lock, and a - negative through a 2000 ohm resistor for unlock, some units will also require 2 extra to connect.
Even though the ground circuits are on different pins in the computer connector, one might be back-feeding to the other relay socket. Connected a spark tester, and used my Power Probe 4 setup in Injector Test Mode to check for fuel injector pulse. Again, but I don't have a 2001 service manual so I can't tell if it will have the same wire colors. If you have it there, use a piece of wire or stretched out paper clip to jump terminals 30 and 87 together in the socket. As for 85, the ground circuit you're testing is switched on and off inside the Engine Computer. Internet Explorer is so miserable to use after getting used to Firefox. The ignition system of a V8 model Dodge cars will include the components like: ammeter, solenoid, battery, ignition switch, distributor, and coil.
High winds, trees down, power out, 'puter dead until a few minutes ago. The test light just takes the place of the relay's coil, but the clip on the battery positive post is taking the place of the missing 12 volts from the ignition switch. On newer models that will occur and the engine will still run if the cam sensor fails but the crank sensor has to work. The pump should run or you should have voltage at the coil pack and injectors. Or are thay all the same. And that's where we should start.
The customer is leaving the vehicle with us over the weekend and we want to test again Monday morning to see if we get a crank no start. The site stopped working on my main computer. You can verify that at the switch connector after you remove the trim covers under the steering wheel. You can double-check that you have voltage on the feed fuse 23, but that one also feeds the starter relay through a different set of contacts in the switch. One of those two circuits has to be not working.
I think you're going to find a defective ignition switch. Whether your an expert Dodge Caravan car alarm installer, Dodge Caravan performance fan or a novice Dodge Caravan enthusiast with a 2001 Dodge Caravan, a Dodge Caravan car alarm wiring diagram can save yourself a lot of time. Hopefully there will be more. With this result you have eliminated the coil pack as the source of the misfire condition or No Spark Condition. Someone had worked on it before me so its a mess.
You can prove that by testing the fuel pressure. There are also shown some connections going to the ammeter, and coil. The codes should read out in the odometer display. For a more accurate test, it is best to leave at least one of the relays installed so there is a load on the circuit. Could thay have put the wrong one in it. How are you determining 86 is ground? I double-checked the relay terminals. Let me know what you fine Avey.
Okay, just when I had everything memorized, they changed things,. Adding More Information If you would like to help the Modified Life community by adding a car security wire schematic, car alarm wire diagram, car remote starter wire diagram, auto remote starter wire diagram or auto security wire diagram to our resource, please feel free to post any additional car wiring information about the 2001 Dodge Caravan on this page. That means you must test for that voltage during engine cranking. Next, move the ground clip for the test light to the battery positive post and probe terminal 85. Chrysler makes that very easy.
