    no bud, it was a friend of mine, he changed the loom as he was getting all kinds of errors but still same, come to conclusion it is ecm, but gotta way with it by limiting the pedal travel

      Wow weird. If that cured it to a degree maybe he can double back and check accelerator pedal. The two middle wires are app1 and app2. Key on you should have 600mv(.6V) on one and 300mV(.3V) on the other. And if you depress the accelerator smoothly voltage should go up respective to pedal movement. Up to about 2v.

    he changed out all parts concerned, as he has a few machines at hand, biggest problem is its not throwing out a fault code?? we both worked for cat dealer, and he branched out on his own, i still work for dealer but this one threw me, as when i hook up software it will not recognise ecm, software used to be diagnozer but now change to trucktool

    hi cliff, do you have experience on the mitsubishi pbp 18n2 powered pallet truck switch on operates fine but when you stop walk away for minute red light flashing 196 showing on screen and the only way it will operate again is switch off then back on,

    I just got this code on my Nissan, prior to it showing up cleaned the throttle body, an then shortly after e43 showed. Engine started running low rpm an odd. I drained vaporizer an it was crazy how much crap came out of it. Now it runs good again but still the code.. does the code need to removed with diagnostic tool?

      Usually you wont need to clear after you repair the problem(s). You can try with a regular OBD2 automotive scan tool, the connextor is under the cup holder taped to harness. And you do not need a million dollar one. One from Harbor freigjt or autozobe will do. I have seen that E43 come on for charging system issues, O2 sensor failure, main injector failure, fuel pressure sensor circuit failure. The criteria for setting a E43 is the ECM failure to drive the fuel mixture lean or rich, so you have to think along those lines. Which you did with cleaning out the regulator. Depending on what year you have, there is also a screen on the fuel inlet to throttle body that gets gunked up too

      On the newer K series the ECM controls the injector. On the older k series there was a separate injector driver module

    I am dealing with the exact same lift its throwing the e-43 but currently will not run at all. Was wondering if you had any luck with it?

    • @CliffH1082
      @CliffH1082  3 года назад +2

      Sorry for late response. I've seen that e43 come on for a variety of reasons. Because it's an air fuel ratio type error there can be several things. In my experience I have seen inoperative o2 sensors be the cause(either sensor side or heater side). Ignition misfires. Some cases failing MAF senssor. One of the most odd was a bad alternator. If system voltage drops too far the ECM goes into a default mode where it ignores the 02. I've also seen bad LPG injectors, or bad gasoline injectors. For the most part that code will trip when o2 voltage too high(rich) or too low(lean).

    • @CliffH1082
      @CliffH1082  3 года назад +1

      If its not running at all now and you have e43 I'd definitely look towards fuel system. If its LPG check pressure at regulator (initial key on about 10psi, cranking and running should be between 4.5-5.5 psi). Over fueling could be a possibility too. Do you hear propane by passing and coming out air cleaner?

      @@CliffH1082 It appears to charge all the way up to the main injector. As it will atmosphere lpg when I remove the hose. I cant really hear anything cranking over. I just threw a new primary injector in it yesterday with no change. Will have to purchase a pressure tester to see what I actually have. Pretty limited on tools.

    • @CliffH1082
      @CliffH1082  3 года назад +1

      Yea man that tester I got is 15 dollars from harbor freight. Just standard vacum/low pressure guage. One more thing, that lpg pressure sensor the middle wirw(if it's a nissan should be white with green trace) is the signal wire. If you back probe it you should get .6-.8volts with key on and cranking. If that voltage is high like 2 or 3volts the ecm thinks that there is too much fuel pressure and it won't control the injector

    • @CliffH1082

      I'd also get back to basics and verify what you are missing. Make sure there's spark, compression,etc. And a quick test to see if you have injection pulse is use a low amp test light and check that fuse underneath the main injector. Your test light should pulse as as you're cranking engine while on that fuse

    hi, having trouble with cat gp35 n, press pedal fast and engine bogs down /hesitant, pretty sure assist injection fault which we changed, opened up wiring check for usual wire issues with these cats, have a constant B+ to assist injector so assuming the return is switch earth going back to ecm and assuming its not switched in ecm , no codes present, tried trucktool software but cannot communicate to ecm, always just getting mismatch to ecm, someone probably swapped out ecm from doner, would you know a way to get around this ecm missmatch issue? very greatful for any help

    • @CliffH1082
      @CliffH1082  2 года назад

      The assist injector negative is supplied by the ecm, usually under high load. Does the unit idle ok?

      @@CliffH1082 hi, thx for reply, yes it idles ok and revs if done slowly but press pedal quick and very hesitant it seems to be assist injector not operating, had this while back on other machines and has always had bad wires to assist injector, do you know if there is anything that influences the ecm switching?

    • @CliffH1082
      @CliffH1082  2 года назад

      Usually when the MAF signal is over 3-3.5v is criteria for ecm to control that injector. The assist injector control wire is pin 11 on the bigger connector. Can do a koeo voltage check, should be clise to battery voltage. Also the spring/check ball assembly in that inj isnt gunked up. Id also verify fuel pressure if you havent. Only bc ive seen those engine rev up fine with the assist not even connected. There are couple of factors to rule out with that symptom. Throttle position, lpg pressure sensor signal in some cases(if ecm cant verify lpg pressure to coordinate with the other inputs injection pulse will be off).
