What I mean by mine description. What could make a short circuit of two injectors bank together ? The engine ECU harness 55 pins unplugged. Injectors first and second negative terminal side have share a wire somewhere and that could be Check Control Module second think could be Cluster and third...
According to our schematic ODD numbered injectors should all 3 only connect to pin 16 and another all 3 only to pin 17 that is for ECU ground only another terminal of the injectors is positive 12v all injectors connected together with 12v battery when ignition is ON position. The ECU harness...
Yes shielding looks good pin 3 of the sensor goes to ECU harness. Do you have any advise how to fix injectors wiring ? The engine ECU has two pins 16 and 17 which controlls injectors ground. ECU pin 16 connected with injectors ground all 3 together is 1-3-5. And ECU pin 17 also connected with 3...
maybe connected to wrong ECU pins if is not make any difference when engine is running when sensor plugged in or unplug out. How may I check if sensor shielding connected good in sensor or not short ?
Connector X1521 (pin 3) carries this shielding connected to ECU ground pin 19. The problem could be sensor wiring terminals is mess it up. Sensor terminal 1 needs to be replaced with terminal 2. In sensor difficult to replace terminals 1 with 2 but in ECU connectors plug it is easy.
oscilloscope or digital meter have same readings. On wiring diagram shown 5v reference from the sensor or from the ECU and that could be check it with scope or meter no metter what tool you are using when engine is running if there is no 5v present when engine is running the sensor connected or...
I just measure something coming out of the sensor which was disconnected from ECU plug while the engine was running the voltage reading was 0.01v and aslo I did check when sensor was connected to the engine ECU plug when engine was running the voltage reading was same 0.01v. what do you thing...
What do you think this 5v on wiring diagram the sensor send small AC voltage to the engine ECU or the engine ECU should have present 5v when ignition is ON ?
Cylinder identification sensor working properly. It is dragging the 0.01v down to zero. New sensor and old used sensors they all have same voltage readings 0.01v when number 6 sylinder spark plug is firing. This sensor seat on spark plug wire of the sixth cylinder and pick up small AC voltage...
Firing all six injectors together without cut-off one group of the three injectors. Cylinder identification sensor should disconnect one group of the three injectors when number six cylinder is firing. Also when ignition is ON the engine ECU should have present 5v at connector of cylinder...
