What is fuel injector driver circuit Performance Bank 1?

OBD II fault code P062D is a generic code that is defined as “Fuel Injector Driver Circuit Performance – Bank 1”, and is set when the PCM (Powertrain Control Module) detects an inconsistency between the number injection command, and injection confirmation signals for one or more fuel injectors.

Where does Fuel Injectors get power from?

It is supplied with pressurized fuel by the fuel pump in your car, and it is capable of opening and closing many times per second. When the injector is energized, an electromagnet moves a plunger that opens the valve, allowing the pressurized fuel to squirt out through a tiny nozzle.

What is a fuel injector driver?

Engines that need high pressure fuel injection rely on injector driver modules to control the fuel injection system. The main purpose of an injector driver module is to control the amount and timing of fuel injection within the vehicle’s system.

What can cause a P0261 code?

Code P0261 is triggered when the voltage in the #1 Cylinder Injector Circuit is too low. The Powertrain Control Module (PCM) uses special transistors—called “drivers”—to turn the Fuel Injectors on and off in the Fuel Injection System.

Does the ECU control the fuel injectors?

Fundamentally, the engine ECU controls the injection of the fuel and, in petrol engines, the timing of the spark to ignite it. It determines the position of the engine’s internals using a Crankshaft Position Sensor so that the injectors and ignition system are activated at precisely the correct time.

How do I test my fuel injectors?

Unplug the electrical connector from the fuel injector you want to test. Turn the ignition switch to the ON position. Touch the terminals (one at a time) of the harness connector with the test light. One of the terminals should make the test light glow, this is the injector power source coming from the computer.

How do I check my injectors?

Zitat von Youtube: And you have power at your fuel injector. Well you'll need to do is to grab yourself a test light and connect it to ground and with the key in the on position.

What does the fuel injector control module do?

The injector control module, also known as the injector driver module, is a “stepping stone” between the powertrain control module and the fuel injectors. It is used to prevent a large amount of voltage going through the powertrain control module.

How do you check low impedance injectors?

How do I know if my injector is low impedance or high impedance? You can measure the resistance across the two electrical terminals of the injector. If the resistance is between 1.5 and 4.0 Ohm you have low impedance injectors. If the resistance is between 8 and 16 Ohm you have high impedance injectors.
