The 4 books provide all I will ever need. Hello I have a 08 Avenger with a 2. Testing power to the injector using a test light Courtesy: 2carpros. The last 5 miles of highway had no traffic so I gunned the engine to 100 mph without issue. I think I will go with the safe way.
This results in better economy, better performance and reduced emissions. Be sure to relieve the fuel rail, fuel pressure, before removing the rail. This code is very similar to P0200, P0201, P0202, P0203, P0205, P0206, P0207, and P0208. Testing with a noid light Courtesy: plusquip. To determine if the injectors are restricted, an injector balance test should be performed using a dedicated tester. Finally check continuity from pin 7 of the data connector and pin 65 of the powertrain connector pink wire. I found the fuse via the labeling inside the fuse cover.
Thanks to anyone who responds. Spark plugs typically need to be replaced every season or 25 hours of use. Other manufacturers sometimes use an alternating pattern in the V-engines. What causes the P0204 code? My problem started the other day after driving from work about30miles to my town and stopped to have dinner with my wife. Using the scan tool, he will then monitor injector operation, along with a noid light installed to the injector wiring to test for cylinder 4 injector and check for proper voltage.
Attach one end of your test light to ground and touch the other to the B+ pin on the injector connector — the tight light should illuminate. Common Symptoms Error Code P0204 is quite unique, as symptoms can be felt even before the Check Engine light is activated in the dashboard, as the vehicle may display rich or lean condition alongside with engine misfires. Oscilloscope peak and hold injector waveform pattern Courtesy: Motor Age Training Oscilloscope saturated waveform pattern Courtesy: Motor Age Training In addition to electrical problems, injectors can experience mechanical failure and become clogged. If the code indeed comes back, the mechanic will proceed on conducting a visual inspection on the injector circuit and the fuel injector itself. In the V-6 configuration, cylinder 4 is at the front right of the engine and in a V-8, cylinder number 5 is in that location. After that, I'm going to go after the fuel injector. I change the coil pack out and checked out the wiring connection but didn't see any issues.
Follow the instructions on the bottle of whatever you get. The best tool for determining injector health is a digital oscilloscope. How many miles on our 4. Regardless of how you approach it, you should get this fixed right away. Measure the resistance of the injector harness circuit between the high side driver circuit and the low side driver circuit for the suspect injector at the injector harness connector. By comparing the waveform on the screen to that of a known good injector, you can quickly pinpoint injector circuit faults.
Either the injector is not properly grounding the circuit, or there is no power to the injector. Your battery is 6 years old and probably needs replacement. This can easily be checked using a simple test light. The solution is here : Dodge Magnum P0204 Possible Solution : Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Injectors can become clogged by particles and fail to operate. It is not great, with missing parts and errors in some sections. These are installed between the fuel injectors and the wiring harness to test for the voltage pulse width of the fuel injector.
In your opinion, are any of the cleaners worth the cost. On a scale of 1 to 5, P0204 is a 3 on the seriousness scale. Update: So I'm kicking myself for not thinking to do this sooner, however I learned a lot by trying to figure this out the hard way. The warm area atop the engine provides shelter for small animals, where they proceed to gnaw the wiring for some strange reason. With the saturated switch, maximum current is applied to the injector while it is opened pulsed. Is the resistance less than 10 Ohms? When the engine is cranked, the test light should illuminate. I did my test based off of this video by Youtuber ScannerDanner starting at about the 5 min mark.
Do you think it is worth the money or know of a better source for a manual? Now don't ask yourself; What should you do with P0204 code? Starting with J9 and working my way up. The code P0204 stands for Injector 4 — Circuit Malfunction. One of the main components in a modern fuel system is the fuel injector. So you should chech it on our car models. Then, the mechanic will test the injector for voltage to confirm proper operation. Start the rig and let it run till it dies. Voltage may be checked at the fuel injector and it may pass fine, then a noid light is installed only to find the pulse width is not correct for the fuel injector.
Is this the correct fuse? Once the code is set, the vehicle will activate its failsafe mode, keeping the engine safe from further damage. These are required service at 100k miles. With the severity of some of these symptoms, caution is advised. Using a scope, you can view a waveform pattern of the injector circuit operation. So it took about 15 min for the engine to finally idle normally and then the car ran like normal. But you should also verify that there is either a + or - bias voltage of 2. Searches related to P0204 - Injector Circuit Malfunction Cylinder 4 p0204 dodge caravan p0204 and p0304 p0204 chrysler town and country injector circuit open cylinder 5 p0204 peugeot 206 p0204 dodge charger p0204 dodge durango p0204 citroen c3.
And they came in real handy when I had to replace my clutch. Then check the resistance between pin 43 if its plug and pin 3 of the data link connector. M25 is simply labeled fuel pump. The manual says to check the ccd bus wires between the module and the rest of the system using the Chrysler diagnostic readout box. Is there any one particular injector cleaner that stands above the rest? Once you have access to the fuel rail, there should be a relief valve on the rail. Is the resistance less than 1 ohm and greater than 0 ohms? A fuel injector Courtesy: waynesgarage. Posted on Jul 12, 2010 answers.
