Some suggested steps for troubleshooting and fix the error code P062D: Sometimes the cause is a defective module (PCM).Faulty electronic fuel injection (EFI) controller.Bad electrical connection in the circuit connector.Breakage or short circuit of electric wires in the injector driver circuit.Failure of one or more fuel injectors (Bank 1).The error code P062D can mean that one or more of the following problems have occurred: It is recommended to correct it as soon as possible to avoid serious damage to the engine or other components. Possible ignition skips in the engine cylinders.įault P062D is a serious error, as it may cause engine and driving problems.
Floating revolutions, as well as attempts to stall at idle.Check engine control lamp on the control panel will light up (the code will be recorded in the memory as a malfunction).The main signal that an error P062D has occurred is the Malfunction Indicator Lamp (MIL) is also known as the CheckEngine Light. The Malfunction Indicator Light (MIL) will also illuminate.
If the PCM detects a fuel injector confirmation signal that is not as expected, code P062D will be stored. This allows the PCM to detect a problem before it affects drivability. In addition to controlling the fuel injection system, the PCM also monitors the feedback resistance in the fuel injector circuit for signs of failure. Since DC battery voltage is already present in the circuit, this initiates precise atomization of fuel from the pressurized fuel injector. The PCM controls the injector’s throttle timing and pulse width by applying a ground pulse to the circuit at the right moment. The fuel injector driver is part of the PCM or electronic fuel injection (EFI) controller. Fuel injectors were introduced as a replacement for the carburetor because they are more efficient and effective in controlling the fuel supply. Bank 1 indicates the engine side containing cylinder number one.įuel systems use a variety of components to control and monitor volume, timing, pressure, etc. Stored code P062D means that the Powertrain Control Module (PCM) has detected a problem with the operation of the fuel injector driver circuit. Technical description and explained code P062D This fault designation applies to all vehicles equipped with OBD-II. Fault code P062D is called “Fuel Injector Driver Circuit Performance (Bank 1)” but in different programs it may be called differently.
