Many problems can easily be found in the harness and connectors. How to Fix Repairs for this error code are pretty straightforward, which will be derived from a thorough diagnosis. If not, consult the factory wiring diagram and repair the power side of the circuit as necessary. The warm area atop the engine provides shelter for small animals, where they proceed to gnaw the wiring for some strange reason. The days of carburetors are long gone. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.
P0304 so as I C indicated the issue is not associated nor caused by spark plugs or spark plug wires. The solution is here : P0204 Possible Solution: The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. Optimizing this mixture means better fuel economy and fewer exhaust emissions. The attached image shows in detail the wiring to the fuel injectors. As I C mentioned these codes P0201. The cylinder 4 fuel injector is the most common cause of P0204, especially on higher mileage vehicles, but that does not mean it does not need to be tested. I think the new sensor was doa - but it seemed to me that it must have been ok since they code wasn't there before the new sensor.

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. If you had cylinder misfire you would get codes P0301. With the saturated switch, maximum current is applied to the injector while it is opened pulsed. How does a mechanic diagnose the P0204 code? How do you troubleshoot code P0204? The information contained on this site is presented for informational purposes only.

The seriousness of this code can range from just the Check Engine Light being present, to the vehicle running poorly and having a lack of power. The usual suspect for this problem is the injector itself, but it always pays to conduct a thorough diagnosis before replacing it. Visually check the connector for damage or broken wires. Make sure there are no frayed wires and rub through to each other or to a metal surface on the engine. Once the code is set, the vehicle will activate its failsafe mode, keeping the engine safe from further damage. If it isn't within specs, then replace the injector.
You might try spraying a little carb cleaner or something similar around the intake with it running and see if the rpm's increase. Injectors can become clogged by particles and fail to operate. The vehicle may exhibit poor acceleration, lack of power, and poor gas milage. On a scale of 1 to 5, P0204 is a 3 on the seriousness scale. I have a 04 Jeep Libery auto 3. The currently selected is for the Jeep makes. 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.
The attached image shows in detail the wiring to the fuel injectors. So I replaced the engine. Information given in this video does not guarantee the desired outcome. Test light test of the 4 injector circuit in my car throwing a P0204 injector circuit malfunction code. The list of automotive Makes at the right edge of the screen. Most recent is a P0204 Injector circuit.
If hard starting continues then more investigation necessary. Next time the difficult starting situation occurs, turn off ignition. I have check the battery connections and it's snugged I'm like two second away of finding the problem and selling it.

If the resistance is excessively low or high it will set this code.
So you should chech it on our car models. The currently selected is for the Chrysler makes. P0204 refer to an issue with the fuel injector circuit. When I checked the 2 wires at the connector were touching. If the code changes, then change the injector. Anyone else experience this - or anyone have experience with the pcm rebuilding services? I really don't want this to be a pcm, but I dont think it could be much else. Everything is purchased by us! Here's my story I hope someone can help.
