    INJ4_F (injector 4 fault) in the PID monitor list would have saved you some time. You can see, in real time, the PCM identify and report/respond to faults. PID may be listed differently depending on scan tool. It's really worth the time to select and monitor PIDs related to the symptoms and active (and stored) codes. Ford FMEM (failure mode effects management) was quite sophisticated for its time, and very reliable. Ford IDS will pre-select PIDs for you, on many models depending on what system you're working on.

    Love the way you show putting fender covers on before you start working on the vehicle. Shows respect for the customer! Imagine if in every video you started by showing the installation of fender covers! Imagine the effect on other shop owners. Imagine the effect on prospective customers. Respect the customer. Respect their vehicle. RESPECT! What the world needs to learn. Why not "you" to start teaching Basic Respect? Lessons in Respect & Professionalism as well as automobile repair! Thank you Sir!

    Coil was open but computer is not smart enough to realize that. It just knows there is a problem and the programmers decided attempting to unstick the injector by turning it on and off is the best option. Kinda like when we get that dead spot in the starter solenoid, we first hit it with a hammer.

    Great diagnosis, however as a DIY, I would check injector resistance on #4, & # 5. If open, replace injector because it is bad. Also repair insulation. I would also pull # 4 & # 5 spark plugs to examine them. Do a tune up if needed. You said it was a 2002, but don't remember if you mentioned the mileage.

  • @RATCHETMAN1001

    you can use an injector tester that u plug to the injector and check amps while you energize it, also you can supply power and ground to injector( its just a coil) and if amps go up its bad if the current goes down its good. this is how all coil windings work and its a quick test, learned it years ago

    I have a 92 Jeep, and went down the bad ECU rabbit hole, even in the 90's ECU's are surprisingly sophisticated, the ECU is constantly running diagnostic code checking for bad injectors, voltage out of range for engine sensors, looking at battery voltage and adjusting coil dwell and will try to keep the engine running down to a battery voltage of 5v, has limpin mode for a bad MAP sensor and setting the idle speed looks at barometric pressure, RPM, vehicle speed, power steering pressure, AC, map sensor, coolant and air intake temp and TPS. I wouldn't be surprised if the ECU had the ability to turn off a bad injector to save the cat but I kinda doubt it since the ECU can't tell you which injector is bad or detect a misfire, but I bet if the engineers had more I/O pins on CPU they could have implemented it.

  • @glowvid
    @glowvid หลายเดือนก่อน

    Id have tested at the ecm connector as soon as i seen burnt wires and flakey ground. And voltage drop tested tge ecm grounds to the body.
    And started w checking battery voltage, alternator voltage, fuel tank at leasr 25% full. And Relative compression at least wot listening test. Then drop tested unplugging coils and injectors to confirm which cylinders are acting up.
    I think what happened was coil shorted on injector and burnt out driver, then burnt further until coil was open. So it was shorted then opned and took ecm w it in the process possibly. I did think of the ecm shutdown strategy as possibility, so id have put injector in and seen if control stopped cutting out

    The ECU is always measuring the resistance of the injector coils and if it doesn't match as you were using the test lead and injector tester which I think is not 16 ohm or at least 5% in range, the ecu will go in limp mode.

    • @johanbotha9889
      @johanbotha9889 4 หลายเดือนก่อน +3

      I guess as Mr Sherwood is saying, the ecu does see some sort of resistance, and it is not like a dead short or open circuit, so it almost tries to auto correct these funny measurements and by doing so every 30 sec there will be a mis fire condition. I think the software engineer figured if he programs a mis fire on that particular faulty cylinder the technician will eventually get to the conclusion that there is a fault by comparing resistance values of different injector coils.

    • @Stoney3K
      @Stoney3K 4 หลายเดือนก่อน +1

      ​@@johanbotha9889If that is the case then there could still be some bad wiring, and with the plug disconnected the ECU should detect a circuit open. If there is still resistance with the plug out, then it could mean a corroded harness.

    • @johanbotha9889
      @johanbotha9889 4 หลายเดือนก่อน +2

      @@Stoney3K Correct, but remember Mr Sherwood couldn't understand why the problem persist while he used his test lamp and injector tester. The ecu is programmed to give a code of mis fire when an open circuit or short occurs. Those ecu's are not as precise as the modern cars because of memory chips and advanced technology and it does detect a problem, the only difference is the programmer didn't physically put a code with the wording of open circuit or short circuit. As I say you need a lot of memory to write a certain language and I think the technology limited him so the best way to assist the technician is by simply saying mis fire on the given injector the fault is on.

    IN THE EVENT THE INJECTORS STARTED TO SHORT (16Ω down to let's say 5 Ω) that would cause the current through the circuit to increase yet not enough to blow the fuse and of course possibly making the wire get real warm . Is the injector continues to fail and go to short-circuit it goes open circuit at the last moment which puts a toll on the wiring the current draw goes up not necessarily enough to blow the fuse at that point and it may be too much for the driver(transistor) inside the computer and there is some damage also also the feedback from that circuit could be part of a strategy to actually shut the injector off at a certain point in time

    When we sense an injector not firing, we turn it off for a half minute, then turn it back on hoping that the initial surge current will free up/ unstick the injector. When we sense the injector not firing again, we keep repeating. We probably should use a hammer to unstick it, but instead we use the computer and surge current.
