The 2 and 7 cylinder connectors must be repaired and supported as per bulletin 05-06-04-047B. Sorry for the book I wrote, but I just wanted to clear up every detail. Typically, there is always battery power at one of the two injector terminals. Injector circuit or injector coil tests may be normal until the engine reaches operating temperature. Lets finish with this gentleman's input and contribution. This will provide a look and see distant generalization of what you may be getting into and some live experiences of those who did.
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. So you should chech it on our car models. Visually check the injector for damage. In some scenarios, cleaning the fuel system may allow the fuel injector to operate properly without needing to be replaced. If necessary peel the tape from the area and look for any chafes into the wires.
What causes the P0208 code? Anyone have any ideas on whether this could end up being something less costly than an injector job? But it can't be an actual injector or coil pack considering the fact that after the fuse box was taken off and placed back on it was fine. Though a fuel injector is the most common cause, all steps should be followed when repairs are performed to avoid not fixing the issue and wasting time and money. This completes the circuit and fuel is sprayed into the cylinder. These are installed into the fuel injector wiring and are a visible way to check for injector operation. With the possibility for poor drivability and the engine shutting off and not restarting, this fault should be taken seriously and diagnosed by a quality mechanic as soon as possible. This wastes valuable time and money.
Clear the trouble codes and then wiggle test the related injector connectors to see if the trouble codes can be induced. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Diesel do run hot, so get ready for some hard bolts to loosen. Need help with a P0200 code? What repairs can fix the P0208 code? It also had a horrible idle and felt like it would shut off. The manufactures resistance value specifications can be found in the vehicle repair manual. Need help with a P0208 code? If you have access to an injector tester, activate the injector and see if it operates. This past weekend I was driving around at normal speed and it lost all power, the service traction control, service stabilitrack, and check engine light began flashing.
On the other hand, the peak and hold design allows maximum current to flow just long enough to open the injector. When the vehicle runs poorly or has drivability issues, care should be taken and a qualified technician should be contacted as soon as possible. Which relay would this be and where is it. Either the injector is not properly grounding the circuit, or there is no power to the injector. Correction Important: If the published diagnostics lead to an injector connector on cylinders 2 and 7, the 2 and 7 cylinder injector connectors must be repaired and supported as per bulletin 05-06-04-047B.
If diagnosis is inconclusive, inspect the injector connections on all related cylinders. 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. Clean and dry the connectors as needed. If you have any doubt as to repairs on your vehicle, please contact your technician. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Please confirm the accuracy of the included equipment by calling us prior to purchase. Testing power to the injector using a test light Courtesy: 2carpros.
Electronic fuel injection has been implemented in cars since the 1980s. The wire looked good so we used the handles to remove the fuse box and put it back on and all codes cleared, and the truck ran great again. To determine if the injectors are restricted, an injector balance test should be performed using a dedicated tester. Regardless of how you approach it, you should get this fixed right away. Should I replace the relay, I have checked the harness and connections and found no problem. The 2 and 7 cylinder connectors must be repaired and supported as per bulletin 05-06-04-047B.
This can easily be checked using a simple test light. Noid lights are used to check the voltage pulse that operates the fuel injector. We are staffed with experienced sales consultants and factory trained technicians. Some of these chafes are very small, possibly the size of a pen tip, but could still cause injector circuit concerns. This replacement pigtail can be used to repair any cylinder except number 2 and number 7. Scan tools with professional features such as live data stream, graphing functions, and the ability to view data over time will be important for diagnosing P0208.
Insulate the harness from the aluminum retaining bracket with suitable material electrical conduit or heater hose so the harness will not chafe again. Stop by our dealership today at 2727 S Havana St. The list of automotive Makes at the right edge of the screen. If the vehicle had only injector circuit codes for P0202 or P0207 with bank shutdown P2146 or P2149 , and the wiggle test induces a P0202 or P0207 to reset, use bulletin number 05-06-04-047B to repair the injector connectors and install the injector harness support kit. An example of an injector control circuit wiring diagram Courtesy: justanswer. When the solenoid inside a fuel injector is energized, it lifts a valve off inside the injector and fuel is sprayed into the engine.
