What makes a fuel injector pulse?
The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.
What should injector pulse be?
Injector pulse width is the amount of time, measured in milliseconds (ms), that a fuel injector stays open (delivers fuel) during a cylinder intake cycle. The typical injector pulse width for an idling engine at normal operating temperature is between 2.5 and 3.5 ms.
Will a bad injector cause a misfire code?
One of the obvious symptoms of a clogged fuel injector is the lighting up of the “Check Engine” light in your dashboard. The fault codes usually associated with a clogged fuel injector can range from misfire codes to lean codes.
What causes fuel injectors in Toyota Tacoma to go bad?
There are two main ways that your injectors can go bad. The first is for them to become clogged, dirty, or unresponsive. When this happens not enough fuel enters into your Tacoma’s combustion chamber. The other way is if the injectors are leaking.
What causes no power to fuel injector pulse?
Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line Question: What causes no power to fuel injectors?
What are the input signals in a pulse injector?
These are the Ne, G, and IGf signals. Inside the ECU, the Ne Signal is used to produce an injection chive signal. The G signal is used to determine the timing of the injection signals. The IGf signal is monitored for fuel delivery fail-safe. (With Conventional EFI, the IG signal is used to produce the injection drive signal.)
Why does my Toyota Tacoma lose so much power?
Loss of Power – Typically, as the engine RPM increases, you won’t be able to “feel” the engine misfire as much. But, you’ll definitely notice the lack of power. Less Fuel Mileage – Your Tacoma’s engine management computer is constantly adjusting the air/fuel ratio and timing to get optimal combustion.
