Fault code P062E is called “Fuel Injector Driver Circuit Performance (Bank 2)” but in different programs it may be called differently. This fault designation applies to all vehicles equipped with OBD-II.
Technical description and explained code P062E
Stored code P062E means that the powertrain control module (PCM) has detected a problem with the operation of the fuel injector driver circuit. Bank 2 indicates the engine side not containing cylinder number one.
Fuel systems use a variety of components to control and monitor volume, timing, pressure, etc. Fuel injectors were introduced as a replacement for the carburetor because they are more efficient and effective in controlling the fuel supply.
The fuel injector driver is part of the PCM or electronic fuel injection (EFI) controller.
The PCM controls the injector’s throttle timing and pulse width by applying a ground pulse to the circuit at the right moment. Since DC battery voltage is already present in the circuit, this initiates precise atomization of fuel from the pressurized fuel injector.
In addition to controlling the fuel injection system, the PCM also monitors the feedback resistance in the fuel injector circuit for signs of failure. This allows the PCM to detect a problem before it affects driveability.
If the PCM detects a fuel injector confirmation signal that is not as expected, code P062E will be stored. The malfunction indicator lamp (MIL) will also illuminate.
Symptoms of vehicle malfunctions
The main signal that an error P062E has occurred is the Malfunction Indicator Lamp (MIL) is also known as the CheckEngine Light.
It can also be warning signs such as:
- Check engine control lamp on the control panel will light up (the code will be recorded in the memory as a malfunction).
- Unstable engine operation.
- Poor acceleration.
- Floating revolutions, as well as attempts to stall at idle.
- Possible ignition skips in the engine cylinders.
- The car engine may run unsteadily.
- Decrease of the engine power.
- Increased fuel consumption.
Fault P062E is a serious error, as it may cause engine and driving problems. It is recommended to correct it as soon as possible to avoid serious damage to the engine or other components.
Factors that can cause this error code
The error code P062E can mean that one or more of the following problems have occurred:
- Failure of one or more fuel injectors (Bank 2).
- Breakage or short circuit of electric wires in the injector driver circuit.
- Bad electrical connection in the circuit connector.
- Faulty electronic fuel injection (EFI) controller.
- Sometimes the cause is a defective module (PCM).
How to fix or reset OBD-2 code P062E
Some suggested steps for troubleshooting and fix the error code P062E:
- Read all stored data and error codes with an OBD-II scan tool.
- Clear the error codes and test drive the vehicle to see if code P062E appears again.
- If the code appears, visually inspect the electrical wires and connectors related to the injector driver circuit.
- Check the operation of the fuel injectors (Bank 2).
- Measure voltage in injectors supply circuit, replace failed injectors if necessary.
- If no problems are found, check and replace the PCM or EFI control module if necessary.
Diagnose and repair of problems
It’s a good idea to first look up the Technical Service Bulletins (TSB) for your specific make of car with the P062E error. If the problem is described, following the instructions can save you time and money in diagnosing and correcting the problem.
Visually inspect all wiring and connectors leading to the fuel injectors (Bank 2). Look carefully for abrasions, bare wires, or breaks. Also look for melted or otherwise damaged areas. Repair if necessary.
Sometimes water or fluids can stagnate in the nozzle seating areas. This increases the chance that the sensor connectors, as well as other electrical connections, will become corroded.
Checking the injectors
If the system wiring and connectors are serviceable, use an oscilloscope to check each individual fuel injector. With the oscilloscope wires connected, note any inconsistencies in the wave pattern. If necessary, replace the defective fuel injectors.
If no fuel injector abnormalities are found, disconnect the circuit from the PCM and the fuel injector. Use a multimeter to determine if the wires are in working order and correct any problems in order to correct error P062E.
If all fuel injectors and system circuits are correct, there is most likely a controller failure or programming error.
On which vehicles does this problem occur most frequently
Fault code P062E can occur on different vehicles but there are statistics on which brands this occurs most often. Here is a list of some of them:
- Ford
- Honda
- Hyundai
- Kia
- Land Rover (Range Rover)
- Mitsubishi
- Ssangyong (Actyon)
